Everything about PATCH (HTTP)

Request method in the HTTP protocol

In computing, the PATCH method is a request method in HTTP for making partial changes to an existing resource. The PATCH method provides an entity containing a list of changes to be applied to the resource requested using the HTTP Uniform Resource Identifier (URI). The list of changes are supplied in the form of a PATCH document. If the requested resource does not exist then the server may create the resource depending on the PATCH document media type and permissions. The changes described in the PATCH document must be semantically well defined but can have a different media type than the resource being patched. Languages such as XML or JSON can be used in describing the changes in the PATCH document. Wikipedia →
