Webhook Receivers: Catch, Inspect, and Replay Incoming Webhooks

You've set up a Stripe webhook. Or a GitHub webhook. Or a Shopify webhook. You click "Send Test Event" and... nothing happens. Was the payload wrong? Did the URL fail? Did your handler crash silently?

Webhook receivers give you a dedicated URL that captures every incoming request — headers, body, method, timestamp — so you can inspect exactly what arrived and replay it when you're ready.

Why You Need a Webhook Receiver

• See the actual payload — no more guessing what the webhook provider sends. See the raw request body, headers, and query parameters.
• Debug without redeploying — capture the payload, fix your handler, and replay the exact same request to test your fix.
• Test locally without tunnels — no ngrok, no Cloudflare tunnels, no port forwarding. The receiver URL is publicly accessible.
• Build handler logic before connecting — develop your webhook processing code against real captured payloads, then switch to the live endpoint when ready.

How It Works on moqapi.dev

1. Create a receiver — go to Webhooks in your dashboard and create a new webhook receiver with a name and optional description.
2. Copy the URL — each receiver gets a unique public URL like https://moqapi.dev/api/webhooks/receive/abc123.
3. Point your provider at it — paste the URL into Stripe, GitHub, Discord, or any webhook source.
4. Inspect incoming requests — every POST to the URL is captured. View method, headers, body, and timestamp in the dashboard.
5. Replay when ready — click replay to re-send any captured request to your actual handler endpoint.

Real-World Example: Debugging a Stripe Payment Webhook

You're building an order fulfilment flow triggered by Stripe's payment_intent.succeeded event. Here's the typical cycle without a receiver:

1. Set up ngrok tunnel.
2. Register the ngrok URL with Stripe.
3. Make a test payment.
4. Check your local server logs.
5. Find the bug.
6. Fix and restart.
7. Repeat from step 3.

With a webhook receiver:

1. Register the receiver URL with Stripe.
2. Make a test payment.
3. Open the receiver in your dashboard — the full payload is captured.
4. Fix your handler code.
5. Click "Replay" to resend the same payload to your updated handler.

No tunnels, no restarts, no repeating the payment flow.

Use Cases Beyond Debugging

• Integration testing — capture real webhook payloads and use them as test fixtures.
• Documentation — show teammates exactly what a provider sends, with real headers and body.
• Monitoring — track webhook delivery patterns over time — frequency, payload size, error rates.

Getting Started

1. Go to Webhooks in your moqapi.dev dashboard.
2. Switch to the Receivers tab.
3. Click Create Receiver and give it a name.
4. Copy the public URL and paste it into your webhook provider.

Every incoming request is captured instantly — no setup, no infrastructure, no waiting.
