Dear All,
We would like to inform you that we plan to ex-change the current API address and endpoints specification for Aion Bank dedicated interface.
On the 1st of April, 2022 we plan to switch to the new dedicated interface. Detailed specification can be found on our new developer portal: https://devportal.aion.eu/. During this transition period, the current API is fully functional, the new API can be tested on sandbox environment whereas production API on WebtoWeb redirection flow.
Consents that were created before 1st April, 2022 will be still active, to use them you still need to use the old api address. 

If you have questions or need more information, do not hesitate to contact us: psd2@aion.be email.

Yours faithfully,
Aion Bank PSD2 Team
