# Add One Project Role to One MongoDB Cloud User

## Parameters

### Path parameters
- **groupId** (string)
  Unique 24-hexadecimal digit string that identifies your project. Use the [/groups](#tag/Projects/operation/listProjects) 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.
- **userId** (string)
  Unique 24-hexadecimal digit string that identifies the pending or active user in the project. If you need to lookup a user's userId or verify a user's status in the organization, use the Return All MongoDB Cloud Users in One Project resource and filter by username.

### 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.
- **pretty** (boolean)
  Flag that indicates whether the response body should be in the prettyprint format.

### Body: application/vnd.atlas.2025-02-19+json (object)
Project-level role to assign to the MongoDB Cloud user.

  Project-level role.
