How to detect if a device was turned on by automation using Webhook?

Hi,

I’m using Blynk Webhook to log device events to my FastAPI backend.
When a device (e.g. a relay on V1) is turned on or off, my webhook receives the datastream update payload (device ID, pin, value, timestamp, etc.).

However, I need to know whether the change came from an Automation or from a manual user action (tapping a button in the app or via API).

From the Webhook placeholders documentation I can’t see any field like automation_id or source in the payload.

Is there any way to distinguish automation-triggered updates from manual or API actions in the webhook payload?
If not, is there a recommended workaround (e.g. setting a marker datastream via automation, or using logs/timeline API to correlate events)?

Thanks in advance for your help!
