Dear developers, We want to inform you that a new release of the XS2A APIs will be available on November 24th 2021 on our production environment. This version brings a breaking change for TPP's in the creation of an account information consent or a payment submission. This breaking change is introduced in order to fully implement the oAuth 2.0 standard using a well-known URL to retrieve the authorize URL. To better understand this breaking change we invite you to read the new HowTo :     To support you in a smooth migration, you can start test this new workflow of the sandbox as of October 6th.   Best regards, vdk bank
