7.9.4 CancelDeliverRequest Method

The CancelDeliverRequest Method requests to cancel a deliver request. The payment service checks if the deliver request can still be cancelled, and if yes, cancels the request, otherwise returns a corresponding Status argument.

If the execution of the Method cannot be done due to some application logic, the Method should return an Uncertain StatusCode and provide details of the failure in the Status output Argument. When the Method returns an Uncertain StatusCode, the Method is considered to be failed, and the TransactionId was not cancelled.

The signature of this Method is specified below. Table 28 and Table 29 specify the Arguments and AddressSpace representation, respectively.

Note: If a TransactionId is used inside a basket (see 7.10), it cannot be cancelled individually. A call of the Method with such a TransactionId should return a -2 Status.

Note: Once a TransactionId has been forwarded to the MachineEngine it is expected that it cannot be cancelled anymore and should return a -2 Status.
