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.

The Atlas Administration API uses HTTP Digest Authentication. Provide your Atlas username as the username and Atlas Administration API key as the password as part of the HTTP request.

This endpoint requires that the Atlas user has the Owner role. To view the available Atlas users, click on Users & Teams in the left-hand navigation.

For complete documentation on configuring API access for an Atlas project, see Get Started with the Atlas Administration API.

Atlas supports a maximum of 100 database users per Atlas project. If you require more than 100 database users on a project, contact Atlas support.

The parameters that this resource requires depend upon the authentication mechanism the database uses. Select from one of the following authentication mechanisms:

Resource

Base URL: https://cloud.mongodb.com/api/atlas/v1.0

POST /groups/{GROUP-ID}/databaseUsers

Request Path Parameters

Path Parameter	Type	Necessity	Description
GROUP-ID	string	Required	Unique 24-hexadecimal string that identifies the project.

Request Query Parameters

This endpoint might use any of the HTTP request query parameters available to all Atlas Administration API resources. All of these are optional.

Name

Type

Necessity

Description

Default

pretty

boolean

Optional

Flag indicating whether the response body should be in a prettyprint format.

false

envelope

boolean

Optional

Flag indicating if Atlas should wrap the response in a JSON envelope.

This option may be needed for some API clients. These clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query.

For endpoints that return one result, the response body includes:


status	HTTP response code
envelope	Expected response body

false

Request Body Parameters

Body Parameter

Type

Necessity

Description

databaseName

string

Required

Database against which the database user authenticates. Database users must provide both a username and authentication database to log into MongoDB.

You may set this parameter value as:

If you don't set an authentication mechanism, Atlas defaults to SCRAM-SHA.

deleteAfterDate

string

Optional

Timestamp in ISO 8601 date and time format in UTC after which Atlas deletes the database user. The specified date must be in the future and within one week of the time you make the API request.

Note

You may include an ISO 8601 time zone designator to ensure that the expiration date occurs with respect to the local time in the specified time zone.

labels

array

Optional

List that contains key-value pairs that tag and categorize the database user.

Each key and value has a maximum length of 255 characters.

"labels": [
   {
     "key": "example key",
     "value": "example value"
   }
 ]

Note

The labels you define are not visible in the Atlas console. They are returned in the response body when you use the Atlas Administration API to get one, get all, or update one database user.

groupId

string

Required

Unique 24-hexadecimal string that identifies the project to which the database user belongs.

roles

array

Required

Array of this user's roles and the databases / collections on which the roles apply. A role allows the user to perform particular actions on the specified database. A role on the admin database can include privileges that apply to the other databases as well.

Note

The available privilege actions for custom roles support a subset of MongoDB commands. See Unsupported Commands in M10+ Clusters for more information.

roles.collectionName

string

Optional

Collection on which the database user has the specified role.

You can specify a collection for the read and readWrite roles. If you do not specify a collection for read and readWrite, the role applies to all collections in the database (excluding some collections in the system. database).

Note

The following table describes the Atlas specific privileges, the database it applies to, and the privilege actions they represent.

Atlas Specific Privilege	Database	Privilege Actions

roles.databaseName

string

Optional

Database on which the database user has the specified role. A role on the admin database can include privileges that apply to the other databases.

roles.roleName

string

Required

Label given to a group of privileges assigned to a database user. This value can either be a built-in role or a custom role.

The admin database accepts these values for the role parameter:

Atlas limits this role to MongoDB databases that it manages. The role allows the user to enable sharding on a database and to shard a collection.

Specific databases accept these values for the role parameter:

dbAdmin
read
readWrite

Specific collections accept these values for the role parameter:

read
readWrite

If you don't specify a collection for the read and readWrite roles, Atlas applies the roles to all collections (excluding some system. collections) in the database.

Note

You can only set a custom role when you set "roles.databaseName" : "admin".

scopes

array

Optional

List of clusters and Atlas Data Lakes that this user can access. Returns an empty array if the database user has access to all the clusters and Atlas Data Lakes in the project. Atlas grants database users access to all resources by default.

"scopes": [
  {
    "name": <resource-name>,
    "type": "CLUSTER"|"DATA_LAKE"
  }
]

scopes.name

string

Required

Name of the cluster or Atlas Data Lake that the database user can access.

scopes.type

string

Required

Type of resource that the database user can access. This parameter returns one of the following values:

CLUSTER
DATA_LAKE

username

string

Required

Username needed to authenticate to the MongoDB database or collection.
