API Documentation

This section provides documentation to implement the SETU standards for Purchase to Pay, Planning & Scheduling and 'Inquiry Pay Equity'.

SETU provides Open API Specifications (OAS) for the message sets, which can be implemented by software systems for standardized message exchange.

In the case of Purchase to Pay, it is also possible to use the international Peppol network infrastructure to transport SETU messages. The Peppol-based exchange of SETU messages is described in the Setu & Peppol documentation.
