How to Test Webflow Webhooks

Webflow webhooks send notifications for CMS collection item changes, form submissions, ecommerce orders, and site publishing events.

Webflow Official Webhook Docs

1. Webflow Webhook Events

Webflow can send the following webhook events to your endpoint:

form_submission
collection_item_created
collection_item_changed
collection_item_deleted
ecomm_new_order
ecomm_order_changed
site_publish

2. Set Up a Test Endpoint with HookRay

Follow these steps to start receiving Webflow webhooks for testing:

  1. Go to HookRay and click "Start Testing — Free" to get your unique webhook URL.
  2. Copy the URL (e.g., https://h.hookray.com/abc123).
  3. In your Webflow dashboard, navigate to the webhook settings and paste the HookRay URL as your endpoint.
  4. Select the events you want to receive (see list above).
  5. Trigger a test event — HookRay will show the incoming webhook in real-time.

3. Sample Webflow Webhook Payload

Here's an example of what a Webflow webhook payload looks like:

payload.json
{
  "triggerType": "form_submission",
  "site": {
    "id": "580e63e98c9a982ac9b8b778"
  },
  "data": {
    "name": "Contact Form",
    "fields": {
      "name": "Alex Kim",
      "email": "alex@example.com",
      "message": "Interested in webhook testing tools"
    },
    "submittedAt": "2026-03-20T16:15:00.000Z"
  }
}

4. Common Issues & Troubleshooting

Webhook not arriving?

Check that your endpoint URL is correct and publicly accessible. Webflow cannot reach localhost URLs — use HookRay's cloud URL instead.

Getting 400 or 500 errors?

HookRay accepts any payload and returns 200 OK by default, so the issue is likely on Webflow's side. Check your webhook configuration and event selection.

Need to verify webhook signatures?

Webflow signs webhook requests for security. Use HookRay to capture the raw headers and body, then implement signature verification in your application code.

5. Next Steps

  • Use HookRay's webhook replay feature to re-send captured webhooks while building your handler
  • Enable smart parsing (Pro plan) to see Webflow-specific fields highlighted automatically
  • Check the Webflow webhook documentation for the complete event reference
