Webhook not being triggered on pull requests

[gpadavala]

We have created a github app with specified hook url (http(s):///api/github/hook), and installed it on the repository
The application is hosted on AKS (behind proxy),

When we create a pull request, we don't see any request being received on our proxy end (if we manually add the same as webhook in the repo, then it reaches but throws an error stating invalid headers/payload)

Ignore, seems it was event subscribe issue on the created github app
