In the EPC VoP scheme
According to the EPC Document 218-23, "Verification Of Payee Scheme Rulebook" first version for public consultation :
The Requesting PSP is the Participant with whom or through whom the Requester intends to make its Account-based Payment. The Requesting PSP receives a Payment Account Number, a Name of the Payment Counterparty and potentially in addition an unambiguous identification code about a Payment Counterparty from the Requester.
The Requesting PSP may also be the Requester.
Upon explicit request by the Requester or due to the laws applicable to the Requesting PSP, this Participant must initiate the request to verify these details about the Payment Counterparty as provided by the Requester.
The Requesting PSP Instantly sends a VOP Request to the PSP managing the Payment Account of the indicated Payment Counterparty.
Worldline provides API based services for scheme participants who need to fulfil this role and intend to comply with all the scheme rules.
The following processing diagram represents the interactions of the Requesting PSP with the Requester and the WL VoP Services :
