Shared architecture

All Yuno mobile SDKs follow the same integration pattern:

1. Create a checkout session server-side via the Checkout Sessions API
2. Initialize the SDK with your public API key
3. Start the checkout by passing the session token to the SDK
4. Handle callbacks for payment success, error, and processing states
5. Verify payment status server-side via webhooks or the GET Payment API

Never use your private secret key in mobile apps. Only the public API key should be embedded in client-side code. All payment creation and verification must happen server-side.

Checkout types

Each mobile SDK supports two checkout modes:

Full Checkout

Pre-built UI that renders all enabled payment methods. Fastest integration path with minimal code.

Seamless Checkout

You control payment method selection. Yuno handles the payment form and tokenization in a single flow.
