Overview

Use Checkout to collect a payment through a hosted page. Your account must have the Collections service enabled. For a full walkthrough, see the Checkout guide. Flow
  1. Use consumer_key and consumer_secret to generate a token in Get Authentication Token.
  2. Cache the token and refresh only on expiry.
  3. Call Create Checkout Request with customer details, amount, and redirect URLs.
  4. Redirect the user to the returned checkout_url (or render it in an iframe).
  5. Receive the final result on your callback_url (see Webhooks).
