IETF HTTPAPI Working Group Drafts and RFCs
The IETF httpapi Working Group is producing the cross-vendor vocabulary that style guides increasingly cite normatively. Includes RFC 9457 Problem Details for HTTP APIs, RFC 9652 Link-Template, RFC 9745 Deprecation header, RFC 9727 api-catalog, plus active drafts on privacy and digest problem types and recently-expired drafts on Idempotency-Key and RateLimit header fields.
