GitHub WebHook call Action on another GitHub repository

Question

Want to trigger a GitHub Action (Repository B) from another GitHub Repository (A) via WebHook. So I try to configuring the WebHook on repository A but I can not specify the Authorization Header that is needed by GitHub Repository B.

Is this possible at all via WebHooks?

Both Repositories belong to the same Organization.

Answer 1

via WebHook

That means repo A WebHook URL is called, and your local endpoint (which listen to the wayhook payload) would need to receive a parameter representing the URL/name of repoB, which it then could curl -X POST in order to trigger its workflow (assuming you have the right token allowed to run API on repoB, in Authorization: bearer <token>).

Considering a webhook JSON payload for a push event include commit(s) message, I would push on repoA a commit with, in its message, the name or URL of repoB.
Your local webhook listener can then extract repoB, and tribber its workflow.
