Accept-Patch

The HTTP Accept-Patch response header advertises which media types the server is able to understand in a PATCH request. For example, a server receiving a PATCH request with an unsupported media type could reply with 415 Unsupported Media Type and an Accept-Patch header referencing one or more supported media types.

The header should appear in OPTIONS requests to a resource that supports the PATCH method. An Accept-Patch header in a response to any request method implicitly means that a PATCH is allowed on the target resource in the request.

Note: IANA maintains a list of official content encodings. The bzip and bzip2 encodings are non-standard but may be used in some cases, particularly for legacy support.

Browser compatibility

Browser compatibility is not relevant for this header. The server sends the header, and the specification doesn't define client behavior.
