PayPal only delivers webhook events whose types are explicitly subscribed on that webhook ID

A webhook registered in the developer dashboard or through the API carries an explicit event_types array. PayPal delivers nothing for types outside that list, and there is no implicit wildcard unless the wildcard type is chosen deliberately. Webhooks are also scoped to a single application's credentials and a single environment, so a sandbox webhook never fires for live traffic.
Adding a new branch to your handler without adding the type to the subscription produces code that is never called and no error anywhere, which reads as a silent gateway outage. Confirm by fetching the webhook and diffing its event types against the branches in your code. Use the dashboard's webhook simulator to fire a specific type at your endpoint before depending on it in production.
