A field called _id
appears in the table that webhooks are written to. This was not sent as part of the event payload. Where does it come from?

Connector: Webhooks

The _id
field is generated by Google Pub/Sub, which Fivetran uses to manage topic subscriptions.

This is an ID that is guaranteed to be unique within a topic. In the context of Fivetran, a topic will often correlate to the webhook endpoint in your Webhooks connector. The definition of that ID can be found in Google's documentation.
