JSON:API — a structured JSON convention for REST APIs.

What is application/vnd.api+json?

application/vnd.api+json is the media type for the JSON:API specification — a widely adopted convention for structuring REST resources, relationships, and pagination in JSON.

Typical usage

APIs that follow the JSON:API spec (Ember Data servers, many enterprise APIs).

Common gotchas

Requests without matching Accept and Content-Type headers may be rejected. JSON:API is strict about media type negotiation.
