Method: cancelFundsReservation

  • Initiates the cancellation of reserved funds from a previous reserveFunds call, freeing the funds without any money movement.

  • Uses reserveFundsRequestId to identify the specific reservation to cancel and relies on a subsequent cancelFundsReservationResultNotification for the final outcome.

  • The combination of requestId and paymentIntegratorAccountId serves as a unique idempotency key for the transaction.

  • An ErrorResponse is returned for processing errors, and an ACKNOWLEDGED response is expected for expired or automatically canceled reservations.

  • The API endpoint for this request is POST https://payment-integrator-e-wallets-api.google.com/integrator-base-path/korea-e-wallets-v1/cancelFundsReservation.

Initiates canceling the funds that were reserved by a reserveFunds call.

This cancels the pending transaction by freeing the reserved funds. The reserveFundsRequestId identifies which funds reservation is being canceled. When this is used, there is no money movement from a customer's account for this transaction. The final result of the cancel is supplied by a call to cancelFundsReservationResultNotification. The requestId within the header is the idempotency key and uniquely identifies this transaction.

If the reservation of funds has expired or the payment integrator has automatically canceled the reservation, consider it a successful cancel rather than an error. Therefore, return an ACKNOWLEDGED response code and call cancelFundsReservationResultNotification.

If the endpoint encounters an error while processing the request, the response body from this endpoint should be of type ErrorResponse.
