Get Automation Stats by ID

**This endpoint allows you to retrieve stats for a single Automation using its ID.** Multiple Automation IDs can be retrieved using the "Get All Automation Stats" endpoint. Once you have an ID, this endpoint will return detailed stats for the single automation specified. You may constrain the stats returned using the `start_date` and `end_date` query string parameters. You can also use the `group_by` and `aggregated_by` query string parameters to further refine the stats returned.
