Ottu Checkout

The Ottu Checkout iOS SDK makes it quick and easy to build an excellent payment experience in your iOS app. We provide powerful and customizable UI screens and elements that can be used out-of-the-box to collect your user's payment details. We also expose the low-level APIs that power those UIs so that you can build fully custom experiences.

Features

Simplified security: We make it simple for you to collect sensitive data such as credit card numbers and remain PCI compliant. This means the sensitive data is sent directly to Ottu instead of passing through your server.

Apple Pay: We provide a seamless integration with Apple Pay.

Localized: We support the following localizations: English, Arabic.

Recommended usage

If you're selling digital products or services that will be consumed within your app, (e.g. subscriptions, in-game currencies, game levels, access to premium content, or unlocking a full version), you must use Apple's in-app purchase APIs. See the App Store review guidelines for more information.

Privacy

The Ottu SDK collects data to help us improve our products and prevent fraud. This data is never used for advertising and is not rented, sold, or given to advertisers.

Requirements

The Ottu requires Xcode 15.0 or later and is compatible with apps targeting iOS 14 or above.
