Webhook Relay

Create temporary webhook endpoints in seconds. Capture, inspect, replay, and forward — all via API.

The Problem

Testing webhooks is painful — spinning up ngrok tunnels, doing curl gymnastics, losing payloads, refreshing request bin tabs. You just want a URL that captures everything and lets you replay it.

⚡

Instant Endpoints

One POST request creates a capture URL. No signup, no tunnels, no config files. Get a webhook URL in under a second.

🔍

Payload Inspection

Every incoming request is stored with full headers, body, query params, IP, and timestamp. Inspect payloads at your own pace.

▶

Replay Requests

Replay any captured request to a target URL with one API call. Debug webhooks by sending the exact same payload again.

➔

Auto-Forwarding

Set a forward URL and every captured request is automatically relayed to your server. Capture and forward simultaneously.

# 1. Create an endpoint
curl -X POST https://api.lazy-mac.com/webhook-relay/api/v1/endpoints
# {"ok":true,"endpoint":{"id":"abc123","capture_url":"https://..."},"api_key":"whk_..."}

# 2. Send a webhook to the capture URL
curl -X POST https://api.lazy-mac.com/webhook-relay/hook/abc123 \
  -H "Content-Type: application/json" \
  -d '{"event":"order.completed","amount":49.99}'

# 3. Inspect what was captured
curl -H "Authorization: Bearer whk_..." \
  https://api.lazy-mac.com/webhook-relay/api/v1/endpoints/abc123/requests

# 4. Replay it to your dev server
curl -X POST -H "Authorization: Bearer whk_..." \
  -H "Content-Type: application/json" \
  -d '{"target_url":"http://localhost:3000/webhooks"}' \
