Auth | Welcome to Afterpay Documentation

This operation is idempotent based on the requestId (if provided), which allows for the safe retry of multiple requests, guaranteeing the payment operation is only performed once.

The consumer’s payment plan will begin at the time of auth approval.

Note: Authorization expires after 13 days and then the transaction is automatically voided. Voided transactions are frozen and cannot be reopened or changed in any way. In this case your only option is to use the v2/checkouts endpoint to create a new order.
