Docs - Create Recurring Invoices API Feature page

[MantisClone]

Problem

The Recurring Invoices feature is referenced on the Invoicing use case page but has no dedicated documentation page. Users clicking the link hit a dead end.

Proposed Solution

Create /api-features/recurring-invoices page covering:

• How recurring invoices differ from recurring payments/subscriptions
• API endpoints for creating recurring invoice schedules
• Use cases: monthly retainers, ongoing service contracts
• Managing, pausing, and canceling recurring schedules
• Webhook notifications for recurring invoice events

Considerations

• Place in "Requests" group in sidebar, alongside "Create Requests"
• Follow same structure as existing API feature pages (/api-features/create-requests)
• Include working code examples
• Update placeholder # link on /use-cases/invoicing

Note

Batch Payments and Payment Detection pages already exist - only Recurring Invoices is missing.
