Concise Problem Details for Constrained Application Protocol (CoAP) APIs, October 2022
Discuss this RFC: Send questions or comments to email@example.com
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.
For the definition of Status, see RFC 2026.
For the definition of Stream, see RFC 8729.
