Provider playbooks
Stripe and GitHub webhook paths.
Provider pages focus on the details that usually cause production surprises: signatures, payload shape, event type filtering, retries, and replay-safe receivers.
Receive billing events, verify signatures, and keep checkout, invoice, and subscription handlers replay-safe.
Use a concrete Stripe-style payload and endpoint example when documenting or testing a billing integration.
Route repository, pull request, issue, workflow, and deployment events without brittle direct delivery.
Compare GitHub push and pull request payloads, headers, delivery IDs, and fields worth logging.
Use ref, before, after, commits, and head_commit.message safely in branch automation.
Route PR actions, base branches, head SHAs, and preview workflows without mixing them into push handling.
Understand event, delivery, hook, content type, and signature headers before debugging GitHub deliveries.
Validate X-Hub-Signature-256 with the raw request body, HMAC-SHA256, and timing-safe comparison.
Handle Shopify topics, HMAC signatures, duplicate delivery IDs, fast 2xx responses, and retries.
Validate X-Twilio-Signature and route status callbacks with payload history and replay controls.
