PayPal - Notifications Webhooks v1
PayPal Webhooks API to subscribe to events and receive real‑time callbacks for payments, refunds, and more.
Description
The PayPal REST APIs use webhooks for event notification. Webhooks are HTTP callbacks that receive notification messages for events. After you configure a webhook listener for your app, you can create a webhook, which subscribes the webhook listener for your app to events. The notifications namespace contains resource collections for webhooks.
