heartbeat

Sends a pulse to indicate that the current session is still in progress, so as not to automatically end it. Sessions are automatically timed out after 2 hours of inactivity — or 30 minutes if the session was paused first. If the user/device does not exist, the API request is skipped and a warning will be returned. You can modify this behavior with the createDisposition option (see below).

This method requires your production API clientKey.
