MoonPay's API-driven swap flow allows you to provide your own swaps UI while still leveraging MoonPay's full swap functionality.

Your UI can allow your customers to select the currencies to exchange and respective amounts, and see the resulting quotes which they can then accept to place a swap with MoonPay.

You can use our API endpoints to drive your UI. For example, you can list the available swap pairs, get quotes for a selected pair and execute quotes.

Swaps are executed by you, on behalf of a MoonPay customer. So, before a quote can be executed, the customer needs to authenticate and KYC with MoonPay. For this you need to embed our widget that initiates an authentication and KYC journey. The widget will provide you with a customer token to use when retrieving and executing the quote.
