UK Finance, FDATA and the Open Banking Implementation Entity (OBIE) are taking steps to improve the flow of information in the market between ASPSPs, AISPs and PISPs on approaches to secure communication under the PSD2 RTS – regardless of the API standard or approach to secure communication being used.

Completing the form will help demonstrate and enable engagement with newly regulated providers. It will also help smooth the transition for customers of third party providers who were in the market prior to 13th January 2018.This Transparency Calendar has been set up to facilitate this voluntary flow of information.It is for each institution to determine whether they answer each question or provide the information in this way – although we would encourage them to do so.The Regulatory Technical Standards under PSD2 set out how the secure communication between newly regulated providers, including AISPs and PISPs, will take place with payment account providers.
