`Click to Pay Drop-In UI` Flow

To integrate the Click to Pay Drop-In UI into your platform, you must follow several integration steps. This section gives a high-level overview of how to integrate and launch Click to Pay Drop-In UI on your webpage and process a transaction. You can find the detailed specifications of the APIs later in this document.

You send a server-to-server API request for a capture context. This request is fully authenticated and returns a JSON Web Token (JWT) that is necessary to invoke the frontend JavaScript library. For information on setting up the server side, see Server-Side Set Up.

You invoke the Unified Checkout JavaScript library using the JWT response from the capture context request. For information on setting up the client side, see Client-Side Set Up.

You use the response from

the Click to Pay Drop-In UI

to retrieve payment credentials for payment processing or other steps.

This figure illustrates the system's payment flow.
