Quick Start
Quick Start
This guide walks you from zero to a live webhook endpoint in under two minutes. No credit card, no CLI, no infrastructure.
1
Create a free account
Head to app.mocklab.dev/signup and sign up with your email. No credit card required — the Free plan is permanent.
After signup you land directly on the Webhook Inspector dashboard.
2
Copy your endpoint URL
Your unique webhook endpoint is shown at the top of the Webhook Inspector page. It looks like this:
https://wh.mocklab.dev/your-unique-id
Click the copy icon next to the URL to copy it to your clipboard.
3
Send your first request
Use any HTTP client — curl, Postman, fetch, or your real webhook source (Stripe, GitHub, etc.). MockLab accepts any HTTP method and any content type.
curl
curl -X POST https://wh.mocklab.dev/your-unique-id \
-H "Content-Type: application/json" \
-d '{
"event": "user.created",
"data": {
"id": "usr_123",
"email": "[email protected]"
}
}' JavaScript (fetch)
await fetch('https://wh.mocklab.dev/your-unique-id', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
event: 'user.created',
data: { id: 'usr_123', email: '[email protected]' }
})
}); 4
Inspect the request
Switch back to the MockLab dashboard. The request appears instantly in the Webhook Inspector feed. Click on it to see:
- Full request headers (Content-Type, User-Agent, custom headers)
- Raw request body (JSON, form data, XML — any format)
- Query parameters
- Source IP address and timestamp
- Request duration
