Python server instance inside kali-linux for testing web-hooks Setting up a test server to receive webhooks is straightforward. Here’s a step-by-step guide:

Step 1: Choose a Test Server Tool

For simplicity, use Python's built-in HTTP server. It’s lightweight and sufficient for testing webhooks.

Option 1: Python Script for Webhooks

1. Open your Kali Linux terminal.

2. Create a new Python script for your webhook listener:

   nano webhook_server.py

3. Paste the following script:

   from http.server import BaseHTTPRequestHandler, HTTPServer
   import json
   
   class WebhookHandler(BaseHTTPRequestHandler):
       def do_POST(self):
           content_length = int(self.headers['Content-Length'])  # Get the payload size
           post_data = self.rfile.read(content_length)          # Read the payload
           print("Webhook received:")
           print(post_data.decode('utf-8'))                     # Print the payload to the terminal
   
           # Respond to the webhook
           self.send_response(200)
           self.send_header('Content-type', 'text/plain')
           self.end_headers()
           self.wfile.write(b"Webhook received successfully!")
   
   if __name__ == "__main__":
       server_address = ('', 8000)  # Listen on port 8000
       httpd = HTTPServer(server_address, WebhookHandler)
       print("Starting webhook server on port 8000...")
       httpd.serve_forever()
   

4. Save and exit (CTRL + O, Enter, then CTRL + X).

Step 2: Start the Webhook Server

1. Run the server:

   python3 webhook_server.py

2. The server will listen on port 8000 for incoming POST requests.

Step 3: Obtain Your Server's Public URL

If you're testing on a local machine and need to expose it to the internet, you can use a tunneling tool like ngrok:

1. Install ngrok (if not already installed):

   sudo apt install ngrok

2. Start an ngrok tunnel:

   ngrok http 8000

3. Ngrok will provide a public URL (e.g., https://abcd1234.ngrok.io) that forwards to your local server. Use this URL as your webhook target.

Step 4: Test Your Webhook Server

1. Use a tool like curl to send a test POST request:

   curl -X POST -H "Content-Type: application/json" \
   -d '{"url": "http://example.com", "user": "admin"}' \
   http://localhost:8000

2. Check the terminal running the server for the printed payload:

   Webhook received:
   {"url": "http://example.com", "user": "admin"}
