Create One Cluster in One Project

POST /api/atlas/v2/groups/{groupId}/clusters
Service accounts Digest auth

Creates one cluster in the specified project. Clusters contain a group of hosts that maintain the same data set. This resource can create clusters with asymmetrically-sized shards. Each project supports up to 25 database deployments. To use this resource, the requesting Service Account or API Key must have the Project Owner role. This feature is not available for serverless clusters.

Please note that using an instanceSize of M2 or M5 will create a Flex cluster instead. Support for the instanceSize of M2 or M5 will be discontinued in January 2026. We recommend using the createFlexCluster API for such configurations moving forward. Deprecated versions: v2-{2024-08-05}, v2-{2023-02-01}, v2-{2023-01-01}

Path parameters

  • groupId string Required

    Unique 24-hexadecimal digit string that identifies your project. Use the /groups 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.

    Format should match the following pattern: ^([a-f0-9]{24})$.

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.

    Default value is false.

  • pretty boolean

    Flag that indicates whether the response body should be in the prettyprint format.

    Default value is false.

      Available MongoDB Versions in Atlas
    • mongoDBVersion string

      Version of MongoDB that the cluster runs.

      Format should match the following pattern: ([\d]+\.[\d]+\.[\d]+).

    • name string

      Human-readable label that identifies the cluster.

      Format should match the following pattern: ^[a-zA-Z0-9][a-zA-Z0-9-]*$.

    • paused boolean

      Flag that indicates whether the cluster is paused.

    • pitEnabled boolean

      Flag that indicates whether the cluster uses continuous cloud backups.

      Continuous Cloud Backups
    • redactClientLogData boolean

      Enable or disable log redaction.

      This setting configures the mongod or mongos to redact any document field contents from a message accompanying a given log event before logging. This prevents the program from writing potentially sensitive data stored on the database to the diagnostic log. Metadata such as error or operation codes, line numbers, and source file names are still visible in the logs.

      Use redactClientLogData in conjunction with Encryption at Rest and TLS/SSL (Transport Encryption) to assist compliance with regulatory requirements.

      Note: changing this setting on a cluster will trigger a rolling restart as soon as the cluster is updated.

      Log Redaction
    • replicaSetScalingStrategy string

      Set this field to configure the replica set scaling mode for your cluster.

      By default, Atlas scales under WORKLOAD_TYPE. This mode allows Atlas to scale your analytics nodes in parallel to your operational nodes.

      When configured as SEQUENTIAL, Atlas scales all nodes sequentially. This mode is intended for steady-state workloads and applications performing latency-sensitive secondary reads.

      When configured as NODE_TYPE, Atlas scales your electable nodes in parallel with your read-only and analytics nodes. This mode is intended for large, dynamic workloads requiring frequent and timely cluster tier scaling. This is the fastest scaling strategy, but it might impact latency of workloads when performing extensive secondary reads.

      Values are SEQUENTIAL, WORKLOAD_TYPE, or NODE_TYPE. Default value is WORKLOAD_TYPE.

      Modify the Replica Set Scaling Mode
    • replicationSpecs array[object]

      List of settings that configure your cluster regions. This array has one object per shard representing node configurations in each shard. For replica sets there is only one object representing node configurations.

      Details that explain how MongoDB Cloud replicates data on the specified MongoDB database.

      Hide replicationSpecs attributes Show replicationSpecs attributes object
      • id string

        Unique 24-hexadecimal digit string that identifies the replication object for a shard in a Cluster. If you include existing shard replication configurations in the request, you must specify this parameter. If you add a new shard to an existing Cluster, you may specify this parameter. The request deletes any existing shards in the Cluster that you exclude from the request. This corresponds to Shard ID displayed in the UI.

        Format should match the following pattern: ^([a-f0-9]{24})$.

      • regionConfigs array[object]

        Hardware specifications for nodes set for a given region. Each regionConfigs object must be unique by region and cloud provider within the replicationSpec. Each regionConfigs object describes the region's priority in elections and the number and type of MongoDB nodes that MongoDB Cloud deploys to the region. Each regionConfigs object must have either an analyticsSpecs object, electableSpecs object, or readOnlySpecs object. Tenant clusters only require electableSpecs. Dedicated clusters can specify any of these specifications, but must have at least one electableSpecs object within a replicationSpec.

        Example:

        If you set "replicationSpecs[n].regionConfigs[m].analyticsSpecs.instanceSize" : "M30", set "replicationSpecs[n].regionConfigs[m].electableSpecs.instanceSize" :"M30"if you have electable nodes and"replicationSpecs[n].regionConfigs[m].readOnlySpecs.instanceSize" : "M30" if you have read-only nodes.

        One of:
        AWS object AZURE object GCP object TENANT object
      • zoneId string

        Unique 24-hexadecimal digit string that identifies the zone in a Global Cluster. This value can be used to configure Global Cluster backup policies.

        Format should match the following pattern: ^([a-f0-9]{24})$.

      • zoneName string

        Human-readable label that describes the zone this shard belongs to in a Global Cluster. Provide this value only if "clusterType" : "GEOSHARDED" but not "selfManagedSharding" : true.

    • rootCertType string

      Root Certificate Authority that MongoDB Atlas cluster uses. MongoDB Cloud supports Internet Security Research Group.

      Value is ISRGROOTX1. Default value is ISRGROOTX1.

    • stateName string

      Human-readable label that indicates any current activity being taken on this cluster by the Atlas control plane. With the exception of CREATING and DELETING states, clusters should always be available and have a Primary node even when in states indicating ongoing activity.

      • IDLE: Atlas is making no changes to this cluster and all changes requested via the UI or API can be assumed to have been applied.
      • CREATING: A cluster being provisioned for the very first time returns state CREATING until it is ready for connections. Ensure IP Access List and DB Users are configured before attempting to connect.
      • UPDATING: A change requested via the UI, API, AutoScaling, or other scheduled activity is taking place.
      • DELETING: The cluster is in the process of deletion and will soon be deleted.
      • REPAIRING: One or more nodes in the cluster are being returned to service by the Atlas control plane. Other nodes should continue to provide service as normal.

      Values are IDLE, CREATING, UPDATING, DELETING, or REPAIRING.

    • tags array[object]

      List that contains key-value pairs between 1 to 255 characters in length for tagging and categorizing the cluster.

      Key-value pair that tags and categorizes a MongoDB Cloud organization, project, or cluster. For example, environment : production.

      Resource Tags
      Hide tags attributes Show tags attributes object
      • key string Required

        Constant that defines the set of the tag. For example, environment in the environment : production tag.

        Minimum length is 1, maximum length is 255.

      • value string Required

        Variable that belongs to the set of the tag. For example, production in the environment : production tag.

        Minimum length is 1, maximum length is 255.

    • terminationProtectionEnabled boolean

      Flag that indicates whether termination protection is enabled on the cluster. If set to true, MongoDB Cloud won't delete the cluster. If set to false, MongoDB Cloud will delete the cluster.

      Default value is false.

    • versionReleaseSystem string

      Method by which the cluster maintains the MongoDB versions. If value is CONTINUOUS, you must not specify mongoDBMajorVersion.

      Values are LTS or CONTINUOUS. Default value is LTS.
