The AI answer we saw
To embed installment payment options into your app, start by selecting a BNPL provider with a developer-friendly API such as Affirm, Klarna, or Afterpay. General steps include: (1) Register for a merchant/developer account and obtain API keys. (2) Use the provider's REST API or SDK to initiate a checkout session, passing order details like amount, currency, and customer info. (3) Redirect or embed the BNPL payment UI using a hosted flow or native SDK component. (4) Handle webhooks for payment confirmation, cancellation, and refund events. (5) Test end-to-end flows in the sandbox environment before going live. Most providers offer detailed API documentation, Postman collections, and sample code on their developer portals.
