We want to again highlight an important change to the UCBA API planned with a release on 17.03.2023.

As communicated on 24.01.2023 (“UniCredit Bank Austria AG: new Sandbox App2App redirect”), the App2App Redirect service for the UniCredit Bank Austria Mobile Banking Apps will be deployed on 17.03.2023, this development is using the SCA Decoupled flow available for the Bank Austria Mobile Banking App and BusinessNet App.

We kindly ask to check and update your internal system configuration in order to guarantee correct SCA redirect and decoupled processes as of 17.03.2023:

  • TPP-Redirect-Preferred => set to “true” will use the REDIRECT SCA method to Internetbanking of supported PSU-ID-Types
  • TPP-Redirect-Preferred => set to “false” will use the DECOUPLED SCA method for App2App Redirect of supported PSU-ID-Types (24YOU = MobileBanking App and BUSINESSNET = BusinessNet App).
  • TPP-Redirect-Preferred missing: The default value when the header is not present is "false".

Please be aware that an incorrect TPP backend setting can lead to rejected payments/consents.
