Concise Problem Details for Constrained Application Protocol APIs
RFC 9290, “Concise Problem Details for Constrained Application Protocol APIs”, is a Proposed Standard document published in October 2022 by T. Fossati, C. Bormann. The canonical text is published by the RFC Editor.
Abstract
This document defines a concise "problem detail" as a way to carry machine-readable details of errors in a Representational State Transfer (REST) response to avoid the need to define new error response formats for REST APIs for constrained environments. The format is inspired by, but intended to be more concise than, the problem details for HTTP APIs defined in RFC 7807.
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.
