It is important that the interplay between the TPP and the ASPSP is seamless, providing customer control in a secure environment. In particular customers should be clear about the permissions they are providing, and the service they will receive.
These guidelines address the customer journey: the screens through which the customer progresses from a TPP app, to authentication in the ASPSP domain, and completion back in the TPP domain.
These guidelines are intended for Open Banking Participants (ASPSPs, AISPs, PISPs and CBPIIs) and competent authorities with regulatory oversight of any Participant that adopts the Open Banking Standard. They should also be of use for Participants who build their own dedicated interfaces or adopt other market initiative standard.
