Remove a User from a Batch of Groups

Removes a user from a batch of groups listed in an ANSI or UTF-8 encoded CSV file maintained in Access Control. You can use the Upload REST API to upload the file to the environment. The file format is as follows:

Group Name
GroupA
GroupB

A user is removed from groups only if these conditions are met:

• The user must exist in the identity domain that services the environment
• The user must be assigned to a pre-defined role in the identity domain
• The groups provided must exist in Access Control and must not be pre-defined groups

Additionally, the user running this API must be authorized to perform this action. This API should be run only by a service administrator in the environment where a user is to be removed from the groups. With this API, you can see which records failed and the reason why they failed in addition to how many records passed and failed.

The presence of status -1 in the response indicates that the removal in progress. Use the job status URI to determine whether the removal is complete. Any non-zero status except -1 indicates failure.

This API is version v1.

Required Roles

Service Administrator or Access Control Manager

This REST API is version v1.
