Why is there a repo:push event when we merge a pull request?

[LuongNguyen43]

I created a webhook to receive 2 event types:  push and merged but when I merge a PR, there is an additional repo:push event sent to my URL, is that event guaranteed to be sent when we merge a PR?

Hi, @LuongNguyen43!

Indeed, this is the expected behavior. This is happening because the merge event is creating a new commit on the destination branch and that is considered a "push". 

I hope this clarifies the situation, but please let me know if you have any questions. 

Kind regards,
Caroline

@Caroline R So how can I know that this push event is due to a pull request being merged? is there any difference between the Pull request's push event and the normal push event?
