  An Atlas [Project/Group
  ID](https://docs.atlas.mongodb.com/tutorial/manage-projects/).

  The ObjectID of your application.

Success.

#### Body: application/json (object)
- **data** (object)

- **resource_id** (object)

- **completed_at** (object)
  The last time a batch was processed from the event stream.

  The value of `completed_at` should be relatively
  close to the current time. If `completed_at` is
  not updating over time, it might mean that the
  event processor (e.g. Device Sync) is down or
  stuck.
- **cluster_time** (object)
  The time of the latest event in the most recently processed batch.

  If the value of `cluster_time` is significantly
  earlier than the `completed_at` time, the event
  processor (e.g. Device Sync) is lagging behind the event.
