Spree Events & Webhooks

Before writing code

Fetch live docs:

1. Fetch https://spreecommerce.org/docs/developer/core-concepts/events for the event bus.
2. Fetch https://spreecommerce.org/docs/developer/core-concepts/webhooks for Webhooks 2.0 (HMAC, retries).
3. Inspect the live lib/spree/event.rb / lib/spree/subscriber.rb and app/subscribers/ in the spree gem for the canonical event names per release.
4. Check the v5.4 announcement for any Webhooks 2.0 changes.
5. For verifying signatures, also check the @spree/sdk if you're consuming webhooks in TypeScript.
