When testing rest webhook subscriptions I can successfully trigger my Zap by delivering a payload to the target_url I get back when setting up the subscription.
I get the following response
```
{"attempt":"0195506a-b87e-2e0e-8c6a-30248bc10a3f","id":"0195506a-b87e-2e0f-8c6a-30248bc10c3f","request_id":"0195506a-b87e-2e0e-8c6a-30248bc11c3f","status":"success"}
```
But I cannot find the documentation of the response. Things like, in case of an error what would the response be? what does attempt, id and request_id mean and would they alway be included in the response etc
