As the example shows, the users to be added to the Information Barrier group (specified as a list of user IDs) must be included in the data parameter.

> #### 🚧 Roles and Privileges

> Calling this endpoint requires the ACCESS\_USER\_PROVISIONING\_API privilege.\

Note: The underlying call to add the user ID is synchronous, adding a large number of ID to an Information Barrier group may result in a long wait for this call to return.\
The maximum number of user IDs that can be passed in one call is conditioned by the size of that parameter: Maximum 2Mb.
