Access Control
Download API definition:
GET https://api.bentley.com/accesscontrol/itwins/{id}/members/users/{memberId}

Retrieves a specific user member for a specified iTwin.

Missing Users

When users are removed from the Bentley Identity Management System, they are not automatically removed from the iTwin. Therefore, it is possible to have a situation where the user is no longer valid, yet they are still a user member of the iTwin. When this happens, the user member will be returned from this API endpoint with the follow values:

{
    "id": <memberId>,
    "email": null,
    "givenName": null,
    "surname": null,
    "organization": null,
    ...
}

You should account for this in your software if you do not want to show these users.

Cleanup

The Access Control API will perform a once-a-week cleanup to remove these "Missing Users". You can rely on this automated clean-up if this timeline is sufficient.

If not, you can use the Remove iTwin User Member API (use the memberId) to remove the user member from the iTwin.

Authentication

Requires Authorization header with valid Bearer token for scope itwin-platform.

For more documentation on authorization and how to get access token visit OAUTH2 Authorization page.

Authorization

The calling user must be a member of the iTwin. Organization Administrator can also retrieve an iTwin user member for any iTwin in their Organization.

An Organization Administrator must have at least one of the following roles assigned in User Management: Account Administrator, Co-Administrator, or CONNECT Services Administrator. For more information about User Management please visit our Bentley Communities Licensing, Cloud, and Web Services wiki page.
