In computing, the PATCH method is a request method in HTTP for making partial changes to an existing resource.^[1] 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).^[1] The list of changes are supplied in the form of a PATCH document.^[1] If the requested resource does not exist then the server may create the resource depending on the PATCH document media type and permissions.^[1] The changes described in the PATCH document must be semantically well defined but can have a different media type than the resource being patched.^[2] Languages such as XML or JSON can be used in describing the changes in the PATCH document.
