How to Test Gumroad Webhooks

Gumroad pings your webhook URL when sales, refunds, disputes, and subscription events occur on your digital products.

1. Gumroad Webhook Events

Gumroad can send the following webhook events to your endpoint:

sale
refund
dispute
dispute_won
cancellation
subscription_restarted
subscription_ended
subscription_updated

2. Set Up a Test Endpoint with HookRay

Follow these steps to start receiving Gumroad 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 Gumroad 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 Gumroad Webhook Payload

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

payload.json
{
  "seller_id": "abc123xyz",
  "product_id": "prod_456",
  "product_name": "Webhook Testing eBook",
  "email": "buyer@example.com",
  "price": 1999,
  "currency": "usd",
  "quantity": 1,
  "is_recurring_charge": false,
  "resource_name": "sale"
}

4. Common Issues & Troubleshooting

Webhook not arriving?

Check that your endpoint URL is correct and publicly accessible. Gumroad 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 Gumroad's side. Check your webhook configuration and event selection.

Need to verify webhook signatures?

Gumroad 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 Gumroad-specific fields highlighted automatically
  • Check the Gumroad webhook documentation for the complete event reference
