Reference
Callbacks
V1 documents existing callback-style delivery. Productized webhook subscriptions are not available yet.
Product status
Productized webhooks remain a deferred product item. Do not promise dashboard webhook subscriptions, event catalogs, retries, or signing secrets as shipped v1 behavior.
Callback-style delivery
Use callback-style patterns only for advanced integrations that already opted into them. Treat them as integration callbacks, not a public webhook product.
Future webhook docs
When productized webhooks ship, this page should add subscription setup, event schemas, signing verification, retry policy, and sandbox testing.
Need rollout review?
Start in the dashboard, choose Script Tag or Server API, and use contact only when you need rollout review, enterprise coordination, or non-standard integration help. Billing beacon rules live in the API concepts guide.
