GitHub Webhook Matrix

CI bots, merge queues, and deployment triggers all pivot on the pull_request event — specifically on action, merged, and the head/base refs. These templates replay the two payloads that matter most: a fresh "opened" PR your automation should pick up, and a "closed" event where merged: true separates a real merge from a discarded branch.

Everything above is encoded into the #data= fragment of the exported URL — deflated and base64url-packed by your browser. Fragments are never sent to any server, so this mock is shareable and private. Paste the URL anywhere: a teammate's browser decodes it identically.
