Create One Stream Instance

POST /api/atlas/v2/groups/{groupId}/streams

Creates one stream instance in the specified project. To use this resource, the requesting Service Account or API Key must have the Project Data Access Admin role, Project Owner role or Project Stream Processing Owner 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.

    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.
