Why can’t I change the transaction/consent status using a specific PSU?

If the transaction/consent status is “received”, it can be possible that the PSU-ID does not match IBAN in the payment initiation or consent creation request. The mapping between PSU-ID and IBAN(s) is documented in the developer portal. If the status doesn’t change even though SCA was performed and the IBAN matches the PSU-ID, check the PSU-ID for typos and case sensitivity.
