export class Subscriptions extends APIResource {
  /**
   * A subscription represents the purchase of a plan by a customer. The customer is
   * identified by either the `customer_id` or the `external_customer_id`, and
   * exactly one of these fields must be provided.
   *
   * By default, subscriptions begin on the day that they're created and renew
   * automatically for each billing cycle at the cadence that's configured in the
   * plan definition.
   *
   * The default configuration for subscriptions in Orb is **In-advance billing** and
   * **Beginning of month alignment** (see
   * [Subscription](/core-concepts##subscription) for more details).
   *
   * In order to change the alignment behavior, Orb also supports billing
   * subscriptions on the day of the month they are created. If
   * `align_billing_with_subscription_start_date = true` is specified, subscriptions
   * have billing cycles that are aligned with their `start_date`. For example, a
   * subscription that begins on January 15th will have a billing cycle from January
   * 15th to February 15th. Every subsequent billing cycle will continue to start and
   * invoice on the 15th.
   *
   * If the "day" value is greater than the number of days in the month, the next
   * billing cycle will start at the end of the month. For example, if the start_date
   * is January 31st, the next billing cycle will start on February 28th.
   *
   * If a customer was created with a currency, Orb only allows subscribing the
   * customer to a plan with a matching `invoicing_currency`. If the customer does
   * not have a currency set, on subscription creation, we set the customer's
   * currency to be the `invoicing_currency` of the plan.
   *
   * ## Customize your customer's subscriptions
   *
   * Prices and adjustments in a plan can be added, removed, or replaced for the
   * subscription being created. This is useful when a customer has prices that
   * differ from the default prices for a specific plan.
   *
   * <Note>
   * This feature is only available for accounts that have migrated to Subscription Overrides Version 2. You can find your
   * Subscription Overrides Version at the bottom of your [Plans page](https://app.withorb.com/plans)
   * </Note>
   *
   * ### Adding Prices
   *
   * To add prices, provide a list of objects with the key `add_prices`. An object in
   * the list must specify an existing add-on price with a `price_id` or
   * `external_price_id` field, or create a new add-on price by including an object
   * with the key `price`, identical to what would be used in the request body for
   * the [create price endpoint](/api-reference/price/create-price). See the
   * [Price resource](/product-catalog/price-configuration) for the specification of
   * different price model configurations possible in this object.
   *
   * If the plan has phases, each object in the list must include a number with
   * `plan_phase_order` key to indicate which phase the price should be added to.
   *
   * An object in the list can specify an optional `start_date` and optional
   * `end_date`. This is equivalent to creating a price interval with the
   * [add/edit price intervals endpoint](/api-reference/price-interval/add-or-edit-price-intervals).
   * If unspecified, the start or end date of the phase or subscription will be used.
   *
   * An object in the list can specify an optional `minimum_amount`,
   * `maximum_amount`, or `discounts`. This will create adjustments which apply only
   * to this price.
   *
   * Additionally, an object in the list can specify an optional `reference_id`. This
   * ID can be used to reference this price when
   * [adding an adjustment](#adding-adjustments) in the same API call. However the ID
   * is _transient_ and cannot be used to refer to the price in future API calls.
   *
   * ### Removing Prices
   *
   * To remove prices, provide a list of objects with the key `remove_prices`. An
   * object in the list must specify a plan price with either a `price_id` or
   * `external_price_id` field.
   *
   * ### Replacing Prices
   *
   * To replace prices, provide a list of objects with the key `replace_prices`. An
   * object in the list must specify a plan price to replace with the
   * `replaces_price_id` key, and it must specify a price to replace it with by
   * either referencing an existing add-on price with a `price_id` or
   * `external_price_id` field, or by creating a new add-on price by including an
   * object with the key `price`, identical to what would be used in the request body
   * for the [create price endpoint](/api-reference/price/create-price). See the
   * [Price resource](/product-catalog/price-configuration) for the specification of
   * different price model configurations possible in this object.
   *
   * For fixed fees, an object in the list can supply a `fixed_price_quantity`
   * instead of a `price`, `price_id`, or `external_price_id` field. This will update
   * only the quantity for the price, similar to the
   * [Update price quantity](/api-reference/subscription/update-price-quantity)
   * endpoint.
   *
   * The replacement price will have the same phase, if applicable, and the same
   * start and end dates as the price it replaces.
   *
   * An object in the list can specify an optional `minimum_amount`,
   * `maximum_amount`, or `discounts`. This will create adjustments which apply only
   * to this price.
   *
   * Additionally, an object in the list can specify an optional `reference_id`. This
   * ID can be used to reference the replacement price when
   * [adding an adjustment](#adding-adjustments) in the same API call. However the ID
   * is _transient_ and cannot be used to refer to the price in future API calls.
   *
   * ### Adding adjustments
   *
   * To add adjustments, provide a list of objects with the key `add_adjustments`. An
   * object in the list must include an object with the key `adjustment`, identical
   * to the adjustment object in the
   * [add/edit price intervals endpoint](/api-reference/price-interval/add-or-edit-price-intervals).
   *
   * If the plan has phases, each object in the list must include a number with
   * `plan_phase_order` key to indicate which phase the adjustment should be added
   * to.
   *
   * An object in the list can specify an optional `start_date` and optional
   * `end_date`. If unspecified, the start or end date of the phase or subscription
   * will be used.
   *
   * ### Removing adjustments
   *
   * To remove adjustments, provide a list of objects with the key
   * `remove_adjustments`. An object in the list must include a key, `adjustment_id`,
   * with the ID of the adjustment to be removed.
   *
   * ### Replacing adjustments
   *
   * To replace adjustments, provide a list of objects with the key
   * `replace_adjustments`. An object in the list must specify a plan adjustment to
   * replace with the `replaces_adjustment_id` key, and it must specify an adjustment
   * to replace it with by including an object with the key `adjustment`, identical
   * to the adjustment object in the
   * [add/edit price intervals endpoint](/api-reference/price-interval/add-or-edit-price-intervals).
   *
   * The replacement adjustment will have the same phase, if applicable, and the same
   * start and end dates as the adjustment it replaces.
   *
   * ## Price overrides (DEPRECATED)
   *
   * <Note>
   * Price overrides are being phased out in favor adding/removing/replacing prices. (See
   * [Customize your customer's subscriptions](/api-reference/subscription/create-subscription))
   * </Note>
   *
   * Price overrides are used to update some or all prices in a plan for the specific
   * subscription being created. This is useful when a new customer has negotiated a
   * rate that is unique to the customer.
   *
   * To override prices, provide a list of objects with the key `price_overrides`.
   * The price object in the list of overrides is expected to contain the existing
   * price id, the `model_type` and configuration. (See the
   * [Price resource](/product-catalog/price-configuration) for the specification of
   * different price model configurations.) The numerical values can be updated, but
   * the billable metric, cadence, type, and name of a price can not be overridden.
   *
   * ### Maximums and Minimums
   *
   * Minimums and maximums, much like price overrides, can be useful when a new
   * customer has negotiated a new or different minimum or maximum spend cap than the
   * default for a given price. If one exists for a price and null is provided for
   * the minimum/maximum override on creation, then there will be no minimum/maximum
   * on the new subscription. If no value is provided, then the default price maximum
   * or minimum is used.
   *
   * To add a minimum for a specific price, add `minimum_amount` to the specific
   * price in the `price_overrides` object.
   *
   * To add a maximum for a specific price, add `maximum_amount` to the specific
   * price in the `price_overrides` object.
   *
   * ### Minimum override example
   *
   * Price minimum override example:
   *
   * ```json
   * {
   *   ...
   *   "id": "price_id",
   *   "model_type": "unit",
   *   "unit_config": {
   *     "unit_amount": "0.50"
   *   },
   *   "minimum_amount": "100.00"
   *   ...
   * }
   * ```
   *
   * Removing an existing minimum example
   *
   * ```json
   * {
   *   ...
   *   "id": "price_id",
   *   "model_type": "unit",
   *   "unit_config": {
   *     "unit_amount": "0.50"
   *   },
   *   "minimum_amount": null
   *   ...
   * }
   * ```
   *
   * ### Discounts
   *
   * Discounts, like price overrides, can be useful when a new customer has
   * negotiated a new or different discount than the default for a price. If a
   * discount exists for a price and a null discount is provided on creation, then
   * there will be no discount on the new subscription.
   *
   * To add a discount for a specific price, add `discount` to the price in the
   * `price_overrides` object. Discount should be a dictionary of the format:
   *
   * ```ts
   * {
   *   "discount_type": "amount" | "percentage" | "usage",
   *   "amount_discount": string,
   *   "percentage_discount": string,
   *   "usage_discount": string
   * }
   * ```
   *
   * where either `amount_discount`, `percentage_discount`, or `usage_discount` is
   * provided.
   *
   * Price discount example
   *
   * ```json
   * {
   *   ...
   *   "id": "price_id",
   *   "model_type": "unit",
   *   "unit_config": {
   *     "unit_amount": "0.50"
   *   },
   *   "discount": {"discount_type": "amount", "amount_discount": "175"},
   * }
   * ```
   *
   * Removing an existing discount example
   *
   * ```json
   * {
   *   "customer_id": "customer_id",
   *   "plan_id": "plan_id",
   *   "discount": null,
   *   "price_overrides": [ ... ]
   *   ...
   * }
   * ```
   *
   * ## Threshold Billing
   *
   * Orb supports invoicing for a subscription when a preconfigured usage threshold
   * is hit. To enable threshold billing, pass in an `invoicing_threshold`, which is
   * specified in the subscription's invoicing currency, when creating a
   * subscription. E.g. pass in `10.00` to issue an invoice when usage amounts hit
   * \$10.00 for a subscription that invoices in USD.
   *
   * ## Limits
   *
   * By default, Orb limits the number of subscriptions per customer to 100.
   *
   * @example
   * ```ts
   * const mutatedSubscription =
   *   await client.subscriptions.create();
   * ```
   */
  create(
    body: SubscriptionCreateParams,
    options?: Core.RequestOptions,
  ): Core.APIPromise<SubscriptionChangesAPI.MutatedSubscription> {
    return this._client.post('/subscriptions', { body, ...options });
  }

  /**
   * This endpoint can be used to update the `metadata`, `net terms`,
   * `auto_collection`, `invoicing_threshold`, and `default_invoice_memo` properties
   * on a subscription.
   *
   * @example
   * ```ts
   * const subscription = await client.subscriptions.update(
   *   'subscription_id',
   * );
   * ```
   */
  update(
    subscriptionId: string,
    body: SubscriptionUpdateParams,
    options?: Core.RequestOptions,
  ): Core.APIPromise<Subscription> {
    return this._client.put(`/subscriptions/${subscriptionId}`, { body, ...options });
  }

   *
   * Subscriptions can be filtered for a specific customer by using either the
   * customer_id or external_customer_id query parameters. To filter subscriptions
   * for multiple customers, use the customer_id[] or external_customer_id[] query
   * parameters.
   *
   * @example
   * ```ts
   * // Automatically fetches more pages as needed.
   * for await (const subscription of client.subscriptions.list()) {
   *   // ...
   * }
   * ```
   */
  list(
    query?: SubscriptionListParams,
    options?: Core.RequestOptions,
  ): Core.PagePromise<SubscriptionsPage, Subscription>;
  list(options?: Core.RequestOptions): Core.PagePromise<SubscriptionsPage, Subscription>;
  list(
    query: SubscriptionListParams | Core.RequestOptions = {},
    options?: Core.RequestOptions,
  ): Core.PagePromise<SubscriptionsPage, Subscription> {
    if (isRequestOptions(query)) {
      return this.list({}, query);
    }
    return this._client.getAPIList('/subscriptions', SubscriptionsPage, { query, ...options });
  }

  /**
   * This endpoint can be used to cancel an existing subscription. It returns the
   * serialized subscription object with an `end_date` parameter that signifies when
   * the subscription will transition to an ended state.
   *
   * The body parameter `cancel_option` determines the cancellation behavior. Orb
   * supports three cancellation options:
   *
   * - `end_of_subscription_term`: stops the subscription from auto-renewing.
   *   Subscriptions that have been cancelled with this option can still incur
   *   charges for the remainder of their term:
   *
   *   - Issuing this cancellation request for a monthly subscription will keep the
   *     subscription active until the start of the subsequent month, and potentially
   *     issue an invoice for any usage charges incurred in the intervening period.
   *   - Issuing this cancellation request for a quarterly subscription will keep the
   *     subscription active until the end of the quarter and potentially issue an
   *     invoice for any usage charges incurred in the intervening period.
   *   - Issuing this cancellation request for a yearly subscription will keep the
   *     subscription active for the full year. For example, a yearly subscription
   *     starting on 2021-11-01 and cancelled on 2021-12-08 will remain active until
   *     2022-11-01 and potentially issue charges in the intervening months for any
   *     recurring monthly usage charges in its plan.
   *   - **Note**: If a subscription's plan contains prices with difference cadences,
   *     the end of term date will be determined by the largest cadence value. For
   *     example, cancelling end of term for a subscription with a quarterly fixed
   *     fee with a monthly usage fee will result in the subscription ending at the
   *     end of the quarter.
   *
   * - `immediate`: ends the subscription immediately, setting the `end_date` to the
   *   current time:
   *
   *   - Subscriptions that have been cancelled with this option will be invoiced
   *     immediately. This invoice will include any usage fees incurred in the
   *     billing period up to the cancellation, along with any prorated recurring
   *     fees for the billing period, if applicable.
   *   - **Note**: If the subscription has a recurring fee that was paid in-advance,
   *     the prorated amount for the remaining time period will be added to the
   *     [customer's balance](list-balance-transactions) upon immediate cancellation.
   *     However, if the customer is ineligible to use the customer balance, the
   *     subscription cannot be cancelled immediately.
   *
   * - `requested_date`: ends the subscription on a specified date, which requires a
   *   `cancellation_date` to be passed in. If no timezone is provided, the
   *   customer's timezone is used. For example, a subscription starting on January
   *   1st with a monthly price can be set to be cancelled on the first of any month
   *   after January 1st (e.g. March 1st, April 1st, May 1st). A subscription with
   *   multiple prices with different cadences defines the "term" to be the highest
   *   cadence of the prices.
   *
   * Upcoming subscriptions are only eligible for immediate cancellation, which will
   * set the `end_date` equal to the `start_date` upon cancellation.
   *
   * ## Backdated cancellations
   *
   * Orb allows you to cancel a subscription in the past as long as there are no paid
   * invoices between the `requested_date` and the current time. If the cancellation
   * is after the latest issued invoice, Orb will generate a balance refund for the
   * current period. If the cancellation is before the most recently issued invoice,
   * Orb will void the intervening invoice and generate a new one based on the new
   * dates for the subscription. See the section on
   * [cancellation behaviors](/product-catalog/creating-subscriptions#cancellation-behaviors).
   *
   * @example
   * ```ts
   * const mutatedSubscription =
   *   await client.subscriptions.cancel('subscription_id', {
   *     cancel_option: 'end_of_subscription_term',
   *   });
   * ```

  /**
   * This endpoint is used to fetch a subscription's usage in Orb. Especially when
   * combined with optional query parameters, this endpoint is a powerful way to
   * build visualizations on top of Orb's event data and metrics.
   *
   * With no query parameters specified, this endpoint returns usage for the
   * subscription's _current billing period_ across each billable metric that
   * participates in the subscription. Usage quantities returned are the result of
   * evaluating the metric definition for the entirety of the customer's billing
   * period.
   *
   * ### Default response shape
   *
   * Orb returns a `data` array with an object corresponding to each billable metric.
   * Nested within this object is a `usage` array which has a `quantity` value and a
   * corresponding `timeframe_start` and `timeframe_end`. The `quantity` value
   * represents the calculated usage value for the billable metric over the specified
   * timeframe (inclusive of the `timeframe_start` timestamp and exclusive of the
   * `timeframe_end` timestamp).
   *
   * Orb will include _every_ window in the response starting from the beginning of
   * the billing period, even when there were no events (and therefore no usage) in
   * the window. This increases the size of the response but prevents the caller from
   * filling in gaps and handling cumbersome time-based logic.
   *
   * The query parameters in this endpoint serve to override this behavior and
   * provide some key functionality, as listed below. Note that this functionality
   * can also be used _in conjunction_ with each other, e.g. to display grouped usage
   * on a custom timeframe.
   *
   * ## Custom timeframe
   *
   * In order to view usage for a custom timeframe rather than the current billing
   * period, specify a `timeframe_start` and `timeframe_end`. This will calculate
   * quantities for usage incurred between timeframe_start (inclusive) and
   * timeframe_end (exclusive), i.e. `[timeframe_start, timeframe_end)`.
   *
   * Note:
   *
   * - These timestamps must be specified in ISO 8601 format and UTC timezone, e.g.
   *   `2022-02-01T05:00:00Z`.
   * - Both parameters must be specified if either is specified.
   *
   * ## Grouping by custom attributes
   *
   * In order to view a single metric grouped by a specific _attribute_ that each
   * event is tagged with (e.g. `cluster`), you must additionally specify a
   * `billable_metric_id` and a `group_by` key. The `group_by` key denotes the event
   * property on which to group.
   *
   * When returning grouped usage, only usage for `billable_metric_id` is returned,
   * and a separate object in the `data` array is returned for each value of the
   * `group_by` key present in your events. The `quantity` value is the result of
   * evaluating the billable metric for events filtered to a single value of the
   * `group_by` key.
   *
   * Orb expects that events that match the billable metric will contain values in
   * the `properties` dictionary that correspond to the `group_by` key specified. By
   * default, Orb will not return a `null` group (i.e. events that match the metric
   * but do not have the key set). Currently, it is only possible to view usage
   * grouped by a single attribute at a time.
   *
   * When viewing grouped usage, Orb uses pagination to limit the response size to
   * 1000 groups by default. If there are more groups for a given subscription,
   * pagination metadata in the response can be used to fetch all of the data.
   *
   * The following example shows usage for an "API Requests" billable metric grouped
   * by `region`. Note the extra `metric_group` dictionary in the response, which
   * provides metadata about the group:
   *
   * ```json
   * {
   *     "data": [
   *         {
   *             "usage": [
   *                 {

   *
   * ## Windowed usage
   *
   * The `granularity` parameter can be used to _window_ the usage `quantity` value
   * into periods. When not specified, usage is returned for the entirety of the time
   * range.
   *
   * When `granularity = day` is specified with a timeframe longer than a day, Orb
   * will return a `quantity` value for each full day between `timeframe_start` and
   * `timeframe_end`. Note that the days are demarcated by the _customer's local
   * midnight_.
   *
   * For example, with `timeframe_start = 2022-02-01T05:00:00Z`,
   * `timeframe_end = 2022-02-04T01:00:00Z` and `granularity=day`, the following
   * windows will be returned for a customer in the `America/Los_Angeles` timezone
   * since local midnight is `08:00` UTC:
   *
   * - `[2022-02-01T05:00:00Z, 2022-02-01T08:00:00Z)`
   * - `[2022-02-01T08:00:00, 2022-02-02T08:00:00Z)`
   * - `[2022-02-02T08:00:00, 2022-02-03T08:00:00Z)`
   * - `[2022-02-03T08:00:00, 2022-02-04T01:00:00Z)`
   *

   *             ],
   *             "view_mode": "periodic"
   *         },
   *         ...
   *     ]
   * }
   * ```
   *
   * ## Decomposable vs. non-decomposable metrics
   *
   * Billable metrics fall into one of two categories: decomposable and
   * non-decomposable. A decomposable billable metric, such as a sum or a count, can
   * be displayed and aggregated across arbitrary timescales. On the other hand, a
   * non-decomposable metric is not meaningful when only a slice of the billing
   * window is considered.
   *
   * As an example, if we have a billable metric that's defined to count unique
   * users, displaying a graph of unique users for each day is not representative of
   * the billable metric value over the month (days could have an overlapping set of
   * 'unique' users). Instead, what's useful for any given day is the number of
   * unique users in the billing period so far, which are the _cumulative_ unique
   * users.
   *
   * Accordingly, this endpoint returns treats these two types of metrics differently
   * when `group_by` is specified:
   *
   * - Decomposable metrics can be grouped by any event property.
   * - Non-decomposable metrics can only be grouped by the corresponding price's
   *   invoice grouping key. If no invoice grouping key is present, the metric does
   *   not support `group_by`.
   *
   * ## Matrix prices
   *
   * When a billable metric is attached to a price that uses matrix pricing, it's
   * important to view usage grouped by those matrix dimensions. In this case, use
   * the query parameters `first_dimension_key`, `first_dimension_value` and
   * `second_dimension_key`, `second_dimension_value` while filtering to a specific
   * `billable_metric_id`.
   *
   * For example, if your compute metric has a separate unit price (i.e. a matrix
   * pricing model) per `region` and `provider`, your request might provide the
   * following parameters:
   *
   * - `first_dimension_key`: `region`
   * - `first_dimension_value`: `us-east-1`
   * - `second_dimension_key`: `provider`
   * - `second_dimension_value`: `aws`
   *
   * @example
   * ```ts
   * const subscriptionUsage =
   *   await client.subscriptions.fetchUsage('subscription_id');
   * ```
   */
  fetchUsage(
    subscriptionId: string,
    query?: SubscriptionFetchUsageParams,
    options?: Core.RequestOptions,
  ): Core.APIPromise<SubscriptionUsage>;
  fetchUsage(subscriptionId: string, options?: Core.RequestOptions): Core.APIPromise<SubscriptionUsage>;
  fetchUsage(
    subscriptionId: string,
    query: SubscriptionFetchUsageParams | Core.RequestOptions = {},
    options?: Core.RequestOptions,
  ): Core.APIPromise<SubscriptionUsage> {
    if (isRequestOptions(query)) {
      return this.fetchUsage(subscriptionId, {}, query);
    }
    return this._client.get(`/subscriptions/${subscriptionId}/usage`, { query, ...options });
  }

  /**
   * This endpoint is used to add and edit subscription
   * [price intervals](/api-reference/price-interval/add-or-edit-price-intervals). By
   * making modifications to a subscription’s price intervals, you can
   * [flexibly and atomically control the billing behavior of a subscription](/product-catalog/modifying-subscriptions).
   *
   * ## Adding price intervals
   *
   * Prices can be added as price intervals to a subscription by specifying them in
   * the `add` array. A `price_id` or `external_price_id` from an add-on price or
   * previously removed plan price can be specified to reuse an existing price
   * definition (however, please note that prices from other plans cannot be added to
   * the subscription). Additionally, a new price can be specified using the `price`
   * field — this price will be created automatically.
   *
   * A `start_date` must be specified for the price interval. This is the date when
   * the price will start billing on the subscription, so this will notably result in
   * an immediate charge at this time for any billed in advance fixed fees. The
   * `end_date` will default to null, resulting in a price interval that will bill on
   * a continually recurring basis. Both of these dates can be set in the past or the
   * future and Orb will generate or modify invoices to ensure the subscription’s
   * invoicing behavior is correct.
   *
   * Additionally, a discount, minimum, or maximum can be specified on the price
   * interval. This will only apply to this price interval, not any other price
   * intervals on the subscription.
   *
   * ## Adjustment intervals
   *
   * An adjustment interval represents the time period that a particular adjustment
   * (a discount, minimum, or maximum) applies to the prices on a subscription.
   * Adjustment intervals can be added to a subscription by specifying them in the
   * `add_adjustments` array, or modified via the `edit_adjustments` array. When
   * creating an adjustment interval, you'll need to provide the definition of the
   * new adjustment (the type of adjustment, and which prices it applies to), as well
   * as the start and end dates for the adjustment interval. The start and end dates
   * of an existing adjustment interval can be edited via the `edit_adjustments`
   * field (just like price intervals). (To "change" the amount of a discount,
   * minimum, or maximum, then, you'll need to end the existing interval, and create
   * a new adjustment interval with the new amount and a start date that matches the
   * end date of the previous interval.)
   *
   * ## Editing price intervals
   *
   * Price intervals can be adjusted by specifying edits to make in the `edit` array.
   * A `price_interval_id` to edit must be specified — this can be retrieved from the
   * `price_intervals` field on the subscription.
   *
   * A new `start_date` or `end_date` can be specified to change the range of the
   * price interval, which will modify past or future invoices to ensure correctness.
   * If either of these dates are unspecified, they will default to the existing date
   * on the price interval. To remove a price interval entirely from a subscription,
   * set the `end_date` to be equivalent to the `start_date`.
   *
   * ## Fixed fee quantity transitions
   *
   * The fixed fee quantity transitions for a fixed fee price interval can also be
   * specified when adding or editing by passing an array for
   * `fixed_fee_quantity_transitions`. A fixed fee quantity transition must have a
   * `quantity` and an `effective_date`, which is the date after which the new
   * quantity will be used for billing. If a fixed fee quantity transition is
   * scheduled at a billing period boundary, the full quantity will be billed on an
   * invoice with the other prices on the subscription. If the fixed fee quantity
   * transition is scheduled mid-billing period, the difference between the existing
   * quantity and quantity specified in the transition will be prorated for the rest
   * of the billing period and billed immediately, which will generate a new invoice.
   *
   * Notably, the list of fixed fee quantity transitions passed will overwrite the
   * existing fixed fee quantity transitions on the price interval, so the entire
   * list of transitions must be specified to add additional transitions. The
   * existing list of transitions can be retrieved using the
   * `fixed_fee_quantity_transitions` property on a subscription’s serialized price
   * intervals.
   *
   * @example
   * ```ts
   * const mutatedSubscription =
   *   await client.subscriptions.priceIntervals(
   *     'subscription_id',
   *   );
   * ```
   */
  priceIntervals(
    subscriptionId: string,
    body: SubscriptionPriceIntervalsParams,
    options?: Core.RequestOptions,
  ): Core.APIPromise<SubscriptionChangesAPI.MutatedSubscription> {
    return this._client.post(`/subscriptions/${subscriptionId}/price_intervals`, { body, ...options });
  }

  /**

   * ```
   */
  redeemCoupon(
    subscriptionId: string,
    body: SubscriptionRedeemCouponParams,

  }

  /**
   * This endpoint can be used to change an existing subscription's plan. It returns
   * the serialized updated subscription object.
   *
   * The body parameter `change_option` determines when the plan change occurs. Orb
   * supports three options:
   *
   * - `end_of_subscription_term`: changes the plan at the end of the existing plan's
   *   term.
   *   - Issuing this plan change request for a monthly subscription will keep the
   *     existing plan active until the start of the subsequent month. Issuing this
   *     plan change request for a yearly subscription will keep the existing plan
   *     active for the full year. Charges incurred in the remaining period will be
   *     invoiced as normal.
   *   - Example: The plan is billed monthly on the 1st of the month, the request is
   *     made on January 15th, so the plan will be changed on February 1st, and
   *     invoice will be issued on February 1st for the last month of the original
   *     plan.
   * - `immediate`: changes the plan immediately.
   *   - Subscriptions that have their plan changed with this option will move to the
   *     new plan immediately, and be invoiced immediately.
   *   - This invoice will include any usage fees incurred in the billing period up
   *     to the change, along with any prorated recurring fees for the billing
   *     period, if applicable.
   *   - Example: The plan is billed monthly on the 1st of the month, the request is
   *     made on January 15th, so the plan will be changed on January 15th, and an
   *     invoice will be issued for the partial month, from January 1 to January 15,
   *     on the original plan.
   * - `requested_date`: changes the plan on the requested date (`change_date`).
   *   - If no timezone is provided, the customer's timezone is used. The
   *     `change_date` body parameter is required if this option is chosen.
   *   - Example: The plan is billed monthly on the 1st of the month, the request is
   *     made on January 15th, with a requested `change_date` of February 15th, so
   *     the plan will be changed on February 15th, and invoices will be issued on
   *     February 1st and February 15th.
   *
   * Note that one of `plan_id` or `external_plan_id` is required in the request body
   * for this operation.
   *
   * ## Customize your customer's subscriptions
   *
   * Prices and adjustments in a plan can be added, removed, or replaced on the
   * subscription when you schedule the plan change. This is useful when a customer
   * has prices that differ from the default prices for a specific plan.
   *
   * <Note>
   * This feature is only available for accounts that have migrated to Subscription Overrides Version 2. You can find your
   * Subscription Overrides Version at the bottom of your [Plans page](https://app.withorb.com/plans)
   * </Note>
   *
   * ### Adding Prices
   *
   * To add prices, provide a list of objects with the key `add_prices`. An object in
   * the list must specify an existing add-on price with a `price_id` or
   * `external_price_id` field, or create a new add-on price by including an object
   * with the key `price`, identical to what would be used in the request body for
   * the [create price endpoint](/api-reference/price/create-price). See the
   * [Price resource](/product-catalog/price-configuration) for the specification of
   * different price model configurations possible in this object.
   *
   * If the plan has phases, each object in the list must include a number with
   * `plan_phase_order` key to indicate which phase the price should be added to.
   *
   * An object in the list can specify an optional `start_date` and optional
   * `end_date`. If `start_date` is unspecified, the start of the phase / plan change
   * time will be used. If `end_date` is unspecified, it will finish at the end of
   * the phase / have no end time.
   *
   * An object in the list can specify an optional `minimum_amount`,
   * `maximum_amount`, or `discounts`. This will create adjustments which apply only
   * to this price.
   *
   * Additionally, an object in the list can specify an optional `reference_id`. This
   * ID can be used to reference this price when
   * [adding an adjustment](#adding-adjustments) in the same API call. However the ID
   * is _transient_ and cannot be used to refer to the price in future API calls.
   *
   * ### Removing Prices
   *
   * To remove prices, provide a list of objects with the key `remove_prices`. An
   * object in the list must specify a plan price with either a `price_id` or
   * `external_price_id` field.
   *
   * ### Replacing Prices
   *
   * To replace prices, provide a list of objects with the key `replace_prices`. An
   * object in the list must specify a plan price to replace with the
   * `replaces_price_id` key, and it must specify a price to replace it with by
   * either referencing an existing add-on price with a `price_id` or
   * `external_price_id` field, or by creating a new add-on price by including an
   * object with the key `price`, identical to what would be used in the request body
   * for the [create price endpoint](/api-reference/price/create-price). See the
   * [Price resource](/product-catalog/price-configuration) for the specification of
   * different price model configurations possible in this object.
   *
   * For fixed fees, an object in the list can supply a `fixed_price_quantity`
   * instead of a `price`, `price_id`, or `external_price_id` field. This will update
   * only the quantity for the price, similar to the
   * [Update price quantity](/api-reference/subscription/update-price-quantity)
   * endpoint.
   *
   * The replacement price will have the same phase, if applicable, and the same
   * start and end dates as the price it replaces.
   *
   * An object in the list can specify an optional `minimum_amount`,
   * `maximum_amount`, or `discounts`. This will create adjustments which apply only
   * to this price.
   *
   * Additionally, an object in the list can specify an optional `reference_id`. This
   * ID can be used to reference the replacement price when
   * [adding an adjustment](#adding-adjustments) in the same API call. However the ID
   * is _transient_ and cannot be used to refer to the price in future API calls.
   *
   * ### Adding adjustments
   *
   * To add adjustments, provide a list of objects with the key `add_adjustments`. An
   * object in the list must include an object with the key `adjustment`, identical
   * to the adjustment object in the
   * [add/edit price intervals endpoint](/api-reference/price-interval/add-or-edit-price-intervals).
   *
   * If the plan has phases, each object in the list must include a number with
   * `plan_phase_order` key to indicate which phase the adjustment should be added
   * to.
   *
   * An object in the list can specify an optional `start_date` and optional
   * `end_date`. If `start_date` is unspecified, the start of the phase / plan change
   * time will be used. If `end_date` is unspecified, it will finish at the end of
   * the phase / have no end time.
   *
   * ### Removing adjustments
   *
   * To remove adjustments, provide a list of objects with the key
   * `remove_adjustments`. An object in the list must include a key, `adjustment_id`,
   * with the ID of the adjustment to be removed.
   *
   * ### Replacing adjustments
   *
   * To replace adjustments, provide a list of objects with the key
   * `replace_adjustments`. An object in the list must specify a plan adjustment to
   * replace with the `replaces_adjustment_id` key, and it must specify an adjustment
   * to replace it with by including an object with the key `adjustment`, identical
   * to the adjustment object in the
   * [add/edit price intervals endpoint](/api-reference/price-interval/add-or-edit-price-intervals).
   *
   * The replacement adjustment will have the same phase, if applicable, and the same
   * start and end dates as the adjustment it replaces.
   *
   * ## Price overrides (DEPRECATED)
   *
   * <Note>
   * Price overrides are being phased out in favor adding/removing/replacing prices. (See
   * [Customize your customer's subscriptions](/api-reference/subscription/schedule-plan-change))
   * </Note>
   *
   * Price overrides are used to update some or all prices in a plan for the specific
   * subscription being created. This is useful when a new customer has negotiated a
   * rate that is unique to the customer.
   *
   * To override prices, provide a list of objects with the key `price_overrides`.
   * The price object in the list of overrides is expected to contain the existing
   * price id, the `model_type` and configuration. (See the
   * [Price resource](/product-catalog/price-configuration) for the specification of
   * different price model configurations.) The numerical values can be updated, but
   * the billable metric, cadence, type, and name of a price can not be overridden.
   *
   * ### Maximums, and minimums
   *
   * Price overrides are used to update some or all prices in the target plan.
   * Minimums and maximums, much like price overrides, can be useful when a new
   * customer has negotiated a new or different minimum or maximum spend cap than the
   * default for the plan. The request format for maximums and minimums is the same
   * as those in [subscription creation](create-subscription).
   *
   * ## Scheduling multiple plan changes
   *
   * When scheduling multiple plan changes with the same date, the latest plan change
   * on that day takes effect.
   *
   * ## Prorations for in-advance fees
   *
   * By default, Orb calculates the prorated difference in any fixed fees when making
   * a plan change, adjusting the customer balance as needed. For details on this
   * behavior, see
   * [Modifying subscriptions](/product-catalog/modifying-subscriptions#prorations-for-in-advance-fees).
   *
   * @example
   * ```ts
   * const mutatedSubscription =
   *   await client.subscriptions.schedulePlanChange(
   *     'subscription_id',
   *     { change_option: 'requested_date' },
   *   );
   * ```
