Grant Negotiation and Authorization Protocol Resource Server Connections
RFC 9767, “Grant Negotiation and Authorization Protocol Resource Server Connections”, is a Proposed Standard document published in April 2025 by J. Richer, F. Imbault. The canonical text is published by the RFC Editor.
Abstract
The Grant Negotiation and Authorization Protocol (GNAP) defines a mechanism for delegating authorization to a piece of software (the client) and conveying the results and artifacts of that delegation to the software. This extension defines methods for resource servers (RSs) to connect with authorization servers (ASs) in an interoperable fashion.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
