Sorry, I’m not sure if I understand you. If you look at the “Trigger webhook” section of the API doc, you will see an example of a webhook response when the model you are watching has changed:
As you can see, the webhook gives you the action that triggered it, which includes the action’s id. I’m not sure what you mean by
can we get the corresponding event so we can link it to the webhook event?
The action that is sent by the webhook IS the corresponding event that triggered the webhook. Please let me know if I am misunderstanding your question.
As for your other question, I don’t believe there is a way to see the source of the event.
