How to test Shopify webhooks locally

Inspect Shopify order, product, and app webhooks during development, then replay them to your local app to iterate quickly.

1. 1
   Create a free RelayFox URL on the homepage (no signup needed).
2. 2
   Paste it as your webhook endpoint: Shopify admin → Settings → Notifications → Webhooks (or via your app config).
3. 3
   Trigger an event (e.g. orders/create) and watch it arrive live in RelayFox.
4. 4
   Run the CLI to forward captured events to your local server:

   npx relayfox forward <endpoint-id> --to http://localhost:3000 --token rfx_...

5. 5
   Inspect headers, body and replay any event as many times as you need.

RelayFox preserves the X-Shopify-Hmac-Sha256 header when forwarding, so Shopify's signature verification works against your local server unchanged.
