What are webhooks and how do I subscribe?

For REST API integrations, webhooks allow us to make a callback to your server for specific triggered events based on your business needs for transaction status, and order fulfillment, among others. 

Perform these steps to subscribe to webhooks: 

1. Create a REST API application in PayPal Developer. 
2. Click "Add Webhooks". 
3. Enter your Webhook URL for us to send event notifications. 
4. Select the event notification types necessary for your application.
5. Click "Save". 
6. Perform a test transaction in Sandbox. 
7. Move your application to live. 

Note: It may not be necessary to manually subscribe to webhooks if you are integrated using one of our preferred partners. The partner will request that PayPal automatically subscribe you to necessary webhook events during the onboarding process.
