We would like to inform you that we are planning to implement a bug-fix on Thursday 21.03.2024, to make the headers of API calls compliant to our specifications. As a result, headers on API response messages will contain only the fields described on our specifications. Additional unspecified header fields from TPP Input message will be excluded. Sandbox will be updated with this change on 23.02.2024 so that TPPs may verify the impact and modify their implementations if required.
