The Scenario

Your checkout works in staging. It breaks in production.

You've connected your fulfillment system to Shopify or WooCommerce. Local testing with curl and Postman looked clean. But once the store goes live, order webhooks arrive in bursts, inventory sync payloads contain stale stock levels, and shipping notification events from your 3PL carry a slightly different schema than the docs promised. Customers see double-charged orders. Your warehouse prints wrong picking lists.

WebhookWatch gives you a dedicated endpoint that mirrors your production URL during development. Every webhook from Shopify's orders/create, WooCommerce's woocommerce.order.created, or your custom inventory microservice lands in the console with full headers, payload diffs, and replay controls. No more guessing why a $2,499.00 order from Amsterdam got stuck in your Stripe reconciliation job.

{
  "id": "ord_7f3a9b2c",
  "total_price": "2499.00",
  "currency": "EUR",
  "line_items": [
    {
      "product_id": "prod_hks-441",
      "variant_id": "var_hks-441-blue-xl",
      "quantity": 1,
      "price": "2499.00"
    }
  ],
  "shipping_address": {
    "first_name": "Lotte",
    "last_name": "Van der Berg",
    "address1": "Prinsengracht 263",
    "city": "Amsterdam",
    "province": "Noord-Holland",
    "zip": "1016 GW",
    "country": "NL"
  },
  "financial_status": "paid",
  "fulfillment_status": null,
  "tags": "wholesale, priority-shipping"
}

With WebhookWatch you see exactly what your endpoint receives — not what the platform documentation says it should receive. Spot missing fields, type mismatches, and encoding issues before they hit your production fulfillment queue.

Why E-commerce Teams Switch

Benefits built for high-stakes integrations

When a webhook payload is off by one decimal place, your inventory system oversells. When a shipping notification arrives late, your customer support inbox floods. WebhookWatch is designed to eliminate those failures before they cost you money.

📦

Payload Diffing

Compare webhook payloads across environments. See exactly which fields changed between your staging Shopify store and the live production payload — down to the nested object level. Catch schema drift from platform updates before your order pipeline crashes.

🔄

Instant Replay

Replay any captured webhook to your local machine or staging endpoint. Test how your inventory sync handles a burst of 50 inventory_levels/update events from a flash sale. No need to recreate complex order scenarios manually.

🔐

Signature Verification

Validate HMAC-SHA256 signatures from Shopify, WooCommerce, and custom platforms in real time. See exactly why a webhook was rejected — wrong secret, tampered body, or clock skew — with one-click fix suggestions.

⏱️

Latency Monitoring

Track end-to-end delivery times for every webhook. If your 3PL's shipping notification takes 47 seconds instead of 3, you'll see it in the timeline. Set alert thresholds so your team gets notified before delays cascade into customer complaints.

📋

Team Shared Console

Share webhook logs with your backend developer, DevOps engineer, and the agency building your Shopify theme. Everyone sees the same event timeline. No more "it works on my machine" when debugging a failed orders/updated callback.

🧪

Mock Webhook Generator

Generate realistic test webhooks for edge cases: partial fulfillments, refunds with tax adjustments, international orders with multiple shipping lines. Feed them into your pipeline without touching a live store.

Integration Examples

Works with your stack out of the box

WebhookWatch integrates with the platforms Dutch e-commerce teams actually use. Point your webhook URL at our endpoint, and everything appears in the console.

🟢

Shopify

Capture orders/create, orders/updated, inventory_levels/update, and fulfillments/create events. Validate Shopify's HMAC signature automatically. Test before you submit your app to the Shopify App Store. Works with both REST Admin API and GraphQL webhooks.

🟤

WooCommerce

Debug woocommerce.order.created, woocommerce.product.updated, and woocommerce.customer.created hooks. WooCommerce webhooks often include unexpected meta fields from plugins like YITH or WooCommerce Subscriptions — see them all in one place.

🔵

Custom Inventory Systems

Got a headless commerce setup with Medusa, Saleor, or a custom Node.js service? Point any webhook source at WebhookWatch. We don't care about the platform — we care about the payload. Validate JSON schema, detect missing required fields, and replay events to your local development server.

🟡

3PL & Shipping Providers

Integrate with TNT Post, PostNL, DHL, or your warehouse's WMS. Capture shipping status webhooks, track label generation events, and verify that your fulfillment callback handles all possible status transitions — from label_created to delivered to returned.

🔴

Payment Gateways

Debug Stripe checkout.session.completed, Mollie payment.paid, and iDEAL callback events. Verify that payment webhooks match the order totals in your store. Catch the edge case where a partial refund creates a mismatched inventory reservation.

Marketplace Connectors

Syncing with Bol.com, Amazon NL, or Marktplaats? Capture their order import webhooks, price change notifications, and stock level sync events. Ensure your marketplace connector doesn't oversell when two channels update inventory simultaneously.
