Return All Serverless Instances from One Project

GET /api/atlas/v2/groups/{groupId}/serverless

Returns details for all serverless instances in the specified project. To use this resource, the requesting API Key must have the Project Read Only role.

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.

    Minimum length is 24, maximum length is 24. 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.

  • includeCount boolean

    Flag that indicates whether the response returns the total number of items (totalCount) in the response.

    Default value is true.

  • itemsPerPage integer

    Number of items that the response returns per page.

    Minimum value is 1, maximum value is 500. Default value is 100.
