Is it possible to create a webhook watching a repo through GraphQL API v4 or REST API v3 ?

I have a oauth token obtained through the oauth procedure : https://developer.github.com/apps/building-integrations/setting-up-and-registering-oauth-apps/.

I am unclear if it is possible to create webhooks watching repos of the user associated to the oauth token with the github APIs.

As I understand things, this is rather done with a github app that specifies a webhook url.

But I would rather do this with the GraphQL API v4 or REST API v3 with tokens obtained through oauth. 

Is it possible to do this ?

Hi @davidgeismar You might have better luck with getting help on this particular topic in our Platform-specific forum. I would recommend trying to open up a Topic there, as that community is specifically tuned into the API and you might get an answer faster.
