I’m working on a package manager for a specific program, and I’m utilizing Github as the host for the packages. People can submit their repositories to add them to the database.

I’ve made a Github App that I’m using from the website now, to fetch information about the repository (tags, contents etc.).

This works great, but I need to keep track of changes in repositories that are listed. Main example is a new tag / release - I need to update my local database with the new version / tag of the package.

Now one idea is to poll the repositories every once in a while and scan for differences - but this feels very inefficient, wasting the ratelimit, bandwidth and resources.

Since the app is private, the webhook only gets activated on changes from my organisation. Is there a way to subscribe “create” events on other (public) repositories, without the need of the owner installing the app? This would save a lot of time and resources.

Kind regards,
Rob
