Cancels an outbound payment order awaiting approval. Transitions status from AWAITING_APPROVAL to CANCELED without submitting it to the provider — no money moves.

​
Preconditions

ConditionFailure
Order must be direction: OUT.PAYMENT_ORDER_INVALID_STATE (HTTP 422).
Order must be in AWAITING_APPROVAL.PAYMENT_ORDER_INVALID_STATE (HTTP 422).
Cancel is only valid before approval. Once an order moves to PENDING (after approve), it cannot be canceled — it will run to completion on the provider’s timeline. To reverse a successful payment, you need a separate refund flow, not a cancel.

​
Effect

  • status → CANCELED (terminal)
  • locked on the wallet is unchanged (the order never reserved funds — reservation happens at approve)
  • The order is never submitted to the provider
The CANCELED state is terminal. Once an order is canceled, it cannot be revived; if you need to re-attempt the operation, create a new order with a different idempotencyKey.
