Update One Serverless Instance in One Project

PATCH /api/atlas/v1.0/groups/{groupId}/serverless/{name}

Updates one serverless instance in the specified project. To use this resource, the requesting Service Account or API Key must have the Project Owner role.

This API can also be used on Flex clusters that were created with the createServerlessInstance endpoint or Flex clusters that were migrated from Serverless instances. This endpoint will be sunset in January 2026. Continuous backups are not supported and serverlessContinuousBackupEnabled will not take effect on these clusters. Please use the updateFlexCluster endpoint instead.

updateFlexCluster

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})$.

  • name string Required

    Human-readable label that identifies the serverless instance.

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

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.
