Following a public consultation on the urgent change requests to the Verification Of Payee (VOP) scheme rulebook and related documents identified by the Verification Of Payee Working Group (VOP WG), the EPC is launching the version 1.1.1 of the VOP Application Programming Interface (API) specifications which sets out the rules for implementing VOP-related APIs based on version 1.1 of the VOP scheme rulebook.
After the launch of the VOP scheme, the VOP WG identified some urgent change requests needed either to solve issues that arose from the deployment of the VOP service, or to clarify some parts of the VOP scheme rulebook, the API specifications and the API Security Framework (ASF).
This version 1.1.1 of the VOP API specifications includes:
- One change in relation with the empty API fields which are no more allowed to be consistent with the standards.
- Clarifications about the character set to be used in the VOP APIs.
- Clarifications about the Timestamp.
- Clarifications about the HTTP Headers, including content-type handling.
The version 1.1.1 of the VOP API specifications will become effective on 20 September 2026.
These specifications cover VOP related messages (i.e., the VOP Requests and the VOP Responses) in the inter-Payment Service Provider (PSP) space only.
Any comments in relation with these EPC VOP Inter-PSP API Specifications can be shared by email to [email protected].
