Headless 360Beginnerwebhooksevents
What is a webhook in headless integrations?
Real World Scenario
Payment provider notifies your site when charge succeeds. You explain webhooks simply.
Expected Answer
• A webhook is an HTTP callback—external system POSTs to your URL when an event occurs
• Used for payment confirmation, shipment updates, and inventory changes
• Your middleware endpoint validates signature, processes payload, updates Salesforce
• Must handle retries and duplicate deliveries safely
• Expose HTTPS endpoints with authentication—not open anonymous URLs
