Create a Database User¶

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.

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

The Atlas API uses HTTP Digest Authentication. Provide your Atlas username as the username and Atlas 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 Configure Atlas API Access.

Atlas supports a maximum of 100 database users per Atlas project.

Note

If you require more than 100 database users on a project, please contact Atlas support.

Syntax¶

POST /groups/{GROUP-ID}/databaseUsers

Request Path Parameters¶

Path Parameter	Type	Necessity	Description
`GROUP-ID`	string	Required	Unique identifier for the project.

Request Query Parameters¶

This endpoint might use any of the HTTP request query parameters available to all Atlas 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 Atlas authenticates the user. A user must provide both a username and authentication database to log into MongoDB.

Accepted values include:

admin if ldapAuthType, x509Type and awsIAMType are omitted or NONE.
$external if:
- ldapAuthType is USER or GROUP, or
- x509Type is MANAGED or CUSTOMER.
- awsIAMType is USER or ROLE.

deleteAfterDate

string

Optional

Timestamp in ISO 8601 date and time format in UTC after which Atlas deletes the 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 of documents

Optional

Array containing 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 UI. They are returned in the response body when you use the Atlas API to get one, get all, or update a database user.

ldapAuthType

string

Optional

Method by which the provided username is authenticated. If no value is given, Atlas uses the default value of NONE.

Accepted values include:


`NONE`	Atlas authenticates this user through SCRAM-SHA, not LDAP.
`USER`	LDAP server authenticates this user through the user's LDAP user. `username` must also be a fully qualified distinguished name, as defined in RFC-2253.
`GROUP`	LDAP server authenticates this user using their LDAP user and authorizes this user using their LDAP group. To learn more about LDAP security, see Set up User Authentication and Authorization with LDAP. `username` must also be a fully qualified distinguished name, as defined in RFC-2253.

x509Type

string

Optional

X.509 method by which the provided username is authenticated. If no value is given, Atlas uses the default value of NONE.

The accepted types are:


`NONE`	User doesn't use X.509 authentication.
`MANAGED`	User to be used with Atlas-managed X.509. Externally authenticated users must be created on the `$external` database.
`CUSTOMER`	User is being created for use with Self-Managed X.509. Users created with this `x509Type` require a Common Name (CN) in the `username` field. For more information, see RFC-2253. Externally authenticated users must be created on the `$external` database.

awsIAMType

string

Optional

If this value is set, the new database user authenticates with AWS IAM credentials. If no value is given, Atlas uses the default value of NONE.

The accepted types are:


`NONE`	The user does not use AWS IAM credentials.
`USER`	New database user has AWS IAM user credentials.
`ROLE`	New database user has credentials associated with an AWS IAM role.

groupId

string

Required

Unique identifier of the Atlas project to which the user belongs.

roles

array of documents

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.

Important

If a user is assigned a custom role, they cannot be assigned any other roles.

roles

.collectionName

string

Required

Collection for which the role applies.

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

When applied to a collection, the read and readWrite roles in Atlas differ slightly from the built-in MongoDB read and readWrite roles.

In Atlas, read provides the following collection-level actions:

In Atlas, readWrite provides the same actions as read, as well as the following additional collection-level actions:

roles

.databaseName

string

Required

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

roles

.roleName

string

Required

Name of the role. This value can either be a built-in role or a custom role.

The following accepted values of role are restricted to the admin database:

atlasAdmin
readWriteAnyDatabase
readAnyDatabase
clusterMonitor
backup
dbAdminAnyDatabase
enableSharding
This role is specific to MongoDB databases that Atlas managed. The role allows the user to enable sharding on a database and to shard a collection.

The following accepted values of role can be applied to a specific database:

dbAdmin
read
readWrite

The following accepted values of role can be applied to a specific collection:

read
readWrite

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

Note

If you specify a custom role name in this field, the roles.databaseName field must be admin.

scopes

array of documents

Optional

Array of clusters and Atlas Data Lakes that this user has access to. If omitted, Atlas grants the user access to all the clusters and Atlas Data Lakes in the project by default.

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

scopes.name

string

Required

Name of the cluster or Atlas Data Lake that the user has access to.

scopes.type

string

Required

Type of resource that the user has access to. Valid values are:

CLUSTER
DATA_LAKE

password

string

Conditional

User's password. Required if:

x509Type, ldapAuthType, and awsIAMType are NONE, meaning that the database user authenticates with SCRAM-SHA.

This field is not included in the server response.

username

string

Required

Username for authenticating to MongoDB.

Must be a fully qualified distinguished name, as defined in RFC-2253, if:

ldapAuthType is USER or GROUP, or
x509Type is CUSTOMER.
