fields Clause: Selecting Fields to Return

Description

Specifies the fields to be returned in the response to a GET operation on a collection.

Applies To

GET method on collections and instances.

Remarks

If the fields clause is sent, the response contains the data for the specified fields and for some fields that are returned unconditionally. Which fields are returned unconditionally varies depending on the resource.

If the fields clause is not sent, all fields are returned.

Limiting the returned data to those fields required by your application and the unconditionally returned fields may significantly improve performance.

A fields clause has the following syntax: fields=<field name>[[,<field name>]]. Field names are separated by a comma (,).

To specify a field, use the "name" value returned in the fields metadata. See Fields.

Limitations

See Limitations section of Defects
