Pattern: ^[-a-zA-Z0-9._]*$

Required: No

description

An optional description of the feature.

Type: String

entityOverrides

Specified users that should always be served a specific variation of a feature. Each user is specified by a key-value pair . For each key, specify a user by entering their user ID, account ID, or some other identifier. For the value, specify the name of the variation that they are to be served.

This parameter is limited to 2500 overrides or a total of 40KB. The 40KB limit includes an overhead of 6 bytes per override.

Type: String

Valid Values: ALL_RULES | DEFAULT_VARIATION

Required: No
