Method: reserveFunds

Reserve funds on a token.

This call synchronously attempts to reserve funds from a previously tokenized account. The response to this message will return the result of that attempt. No money is directly moved as the result of this call. The requested amount of funds should be reserved until a captureFundsReservation, a cancelFundsReservation, or until the reservation has reached the reservationExpirationTimestamp specified in the ReserveFundsResponse. The combination of requestId within the header and paymentIntegratorAccountId is the idempotency key and uniquely identifies this transaction. All mutations on this transaction (cancelFundsReservation, captureFundsReservation) populate the requestId value in their reserveFundsRequestId field.

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

An example request looks like:

In that case, the scope would be "visa" and the rawCode would be whatever the VISA network returned.

This value is required if the result is not SUCCESS.

REQUIRED: The expiration timestamp for this funds reservation represented as milliseconds since epoch.
installmentPlan
