# Add One MongoDB Cloud User to One Project

**POST /api/atlas/v2/groups/{groupId}/access**

Adds one MongoDB Cloud user to the specified project. If the MongoDB Cloud user is not a member of the project's organization, then the user must accept their invitation to the organization to access information within the specified project. If the MongoDB Cloud User is already a member of the project's organization, then they will be added to the project immediately and an invitation will not be returned by this resource. To use this resource, the requesting Service Account or API Key must have the Group User Admin role.


## Servers

## Authentication methods
- Service accounts

## 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.

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