IETF HTTPAPI Working Group Drafts and RFCs is one of 11 APIs that [API Style Guides](https://apis.io/providers/style-guides/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include IETF, HTTP, REST, Problem Details, and Rate-Limit.

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.
