Confirm a payment request initiation
This method allows the PISP :
- Either to confirm a payment initiation request previously sent to the ASPSP for a given PSU through a POST / paymentRequests request ;
- Or to confirm the cancellation of a payment initiation request sent to the ASPSP for a given PSU through a POST / paymentRequests request, when the payment has not been executed yet ;
This feature will be implemented with STET standard v188.8.131.52. For the moment, a V1.4.0 call using this request will return a HTTP 405 error code.
