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.

Base URL: 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

copy

POST /api/atlas/v1.0/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 may use any of the HTTP request query parameters available to all Atlas API resources. These are all optional.

Name	Type	Description	Default
pageNum	integer	Page number (1-based).	1
itemsPerPage	integer	Maximum number of items to return, up to a maximum of 100.	100
pretty	boolean	Indicates whether the response body should be in a prettyprint format.	false
envelope	boolean	Indicates whether or not to wrap the response in an envelope. Some API 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, response body includes: status HTTP response code envelope The expected response body For endpoints that return a list of results, the results object is an envelope. Atlas adds the status field to the response body.

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" } ]
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	string 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. 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: collStats dbHash find listIndexes In Atlas, readWrite provides the same actions as read, as well as the following additional collection-level actions: convertToCapped createCollection createIndex dropCollection dropIndex insert remove update
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.
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. Must be an Amazon Resource Name (ARN) if: awsIAMType is USER or ROLE.

Response Elements

If you set the query element envelope to true, the response is wrapped by the content object.
