Webhook URL Builder

Construct webhook payloads visually. Set the URL, HTTP method, custom headers, and JSON body. Preview what would be sent and copy as a cURL command or JavaScript fetch() call.

Headers
Request Body (JSON)
curl -X POST \
  'https://api.example.com/webhook' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer YOUR_TOKEN' \
  -d '{ "event": "user.created", "data": { "id": 123, "email": "user@example.com", "name": "John Doe" }}'

Build and preview webhook requests. Nothing is sent — use the generated code in your terminal or app.

How to Build Webhook Requests

Compose HTTP requests and export them as cURL or fetch() code with The IT Hustle's free Webhook Builder.

  1. 1
    Set the method and URLChoose GET, POST, PUT, PATCH, or DELETE and enter the endpoint URL you're targeting.
  2. 2
    Add your headersEdit the key-value header table — Content-Type and Authorization are scaffolded for you, and you can add as many as you need.
  3. 3
    Write the bodyFor POST, PUT, and PATCH requests, compose the JSON payload in the body editor.
  4. 4
    Pick an output formatSwitch between a ready-to-run cURL command, a JavaScript fetch() snippet with error handling, or a raw HTTP preview.
  5. 5
    Copy and use itClick Copy and paste the command into your terminal or the snippet into your codebase.

Frequently Asked Questions

No — it generates the code for you to run yourself. Nothing is transmitted to your endpoint (or anywhere else), which means you can safely draft requests containing real API keys.

A webhook is an HTTP request one service sends to another when an event happens — a push notification between servers. When you're building or testing a webhook receiver, this tool composes the exact requests it should expect.

cURL for testing from the terminal or sharing a reproducible request in a bug report; fetch() when you're implementing the call in a JavaScript app. Both are generated from the same request definition, so they're interchangeable.

Add it as a header — most APIs use Authorization: Bearer YOUR_TOKEN, which is why the Authorization header is pre-scaffolded. API-key services may use a custom header like X-API-Key instead; add whatever your API's docs specify.
