Actions are a means of extending Common REST APIs and are defined by the resource provider, so the actions you can use depend on the implementation.

The standard action indicated by _action=create is described in Create.


You can use the following parameters. Other parameters might depend on the specific action implementation:


Format the body of the response.


Return only the specified fields in the body of the response.

The field values are JSON pointers. For example if the resource is {"parent":{"child":"value"}}, parent/child refers to the "child":"value".

If the field is left blank, the server returns all default values.
