Affirm checkout flow



This schema is relevant for any client-side integration via web or mobile.

## 1. Online checkout

  • The customer and merchant submit the order information

  • The client communicates that information to Affirm

  • Affirm renders the checkout experience and on loan confirmation by the customer and returns a `checkout_token`.

## 2. Create an order

Your front-end sends the `checkout_token` to your server (via POST, GET or a [Webhook](🔗)).

## 3. Manage order

Your server code receives the `checkout_token` and then uses it to [initiate a charge](🔗).

Affirm's checkout

Affirm will host the [full checkout experience](🔗) based on the request details. For web, use `Affirm.js`. For mobile, use **iOS** and/or **Android** SDKs.
