Return All MongoDB Cloud Users in One Project

GET /api/atlas/v2/groups/{groupId}/users

Returns details about the pending and active MongoDB Cloud users associated with the specified project. To use this resource, the requesting Service Account or API Key must have the Project Read Only role.

Note: This resource cannot be used to view details about users invited via the deprecated Invite One MongoDB Cloud User to Join One Project endpoint.

Note: To return both pending and active users, use v2-{2025-02-19} or later. If using a deprecated version, only active users will be returned. Deprecated versions: v2-{2023-01-01}

Deprecated: Invite One MongoDB Cloud User to Join One Project

Path parameters

  • groupId string Required

    Unique 24-hexadecimal digit string that identifies your project. Use the /groups endpoint to retrieve all projects to which the authenticated user has access.

    NOTE: Groups and projects are synonymous terms. Your group id is the same as your project id. For existing groups, your group/project id remains the same. The resource and corresponding endpoints use the term groups.

    Format should match the following pattern: ^([a-f0-9]{24})$.

Query parameters

  • envelope boolean

    Flag that indicates whether Application wraps the response in an envelope JSON object. Some API clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query. Endpoints that return a list of results use the results object as an envelope. Application adds the status parameter to the response body.

    Default value is false.

  • includeCount boolean

    Flag that indicates whether the response returns the total number of items (totalCount) in the response.

    Default value is true.

  • itemsPerPage integer

  • flattenTeams boolean

    Flag that indicates whether the returned list should include users who belong to a team with a role in this project. You might not have assigned the individual users a role in this project. If "flattenTeams" : false, this resource returns only users with a role in the project. If "flattenTeams" : true, this resource returns both users with roles in the project and users who belong to teams with roles in the project.

    Default value is false.

  • includeOrgUsers boolean

    Flag that indicates whether the returned list should include users with implicit access to the project, the Organization Owner or Organization Read Only role. You might not have assigned the individual users a role in this project. If "includeOrgUsers": false, this resource returns only users with a role in the project. If "includeOrgUsers": true, this resource returns both users with roles in the project and users who have implicit access to the project through their organization role.

    Default value is false.
