The only webhook this platform's roadmap currently names is a Stripe webhook for payment and subscription events, as part of the Purchase → License → Provisioning → Deployment → Activation pipeline documented in docs/COMMERCE_ROADMAP.md. No Stripe key exists in this deployment and no webhook endpoint is registered.

The platform's core invariant applies here too: a successful payment must never, by itself, cause a product to become reachable. A webhook, when it exists, may create or update a License — it will never advance a Deployment past its initial requested state.
