You can take a few extra steps to prevent malicious developers accessing your requests.

• Use HTTPS
• Set Up Your Firewall
• Use a Token or Secure Key
• Enable HTTP Body Encryption
• Use Random Initialization Vector

Use HTTPS

Use (https://) instead of (http://) in your URL to ensure a more secure communication channel.

Set Up Your Firewall

Use the required firewall settings. See Firewall Settings.

Use a Token or Secure Key

In the URL, add a secret key to all requests received via a Webhook, for example: https://your-url/resource?secret-key=xxxxxxxxxxxxxx.
When your server receives a request, but the authorization fails, send a response back with the HTTP response code ‘401 Unauthorized’.

Enable HTTP Body Encryption

You can enable encryption in the HTTP body. Many cipher methods are available.

For decryption, you need:

• The HTTP body (base64 encoded if encryption is enabled)
• The selected cipher method
• The secret key
• The iv (if you enabled random initialization vector)

Tip: For an example decryption code, see Processing Webhook Requests.

Note: If you enable encryption, you must set up a secret key for encryption and decryption.

Use Random Initialization Vector

Random initialization vector is a commonly used technique. To use this technique, use the “iv” URL parameter. See To Use Dynamic URLs section.

Example URL: https://your-url/resource?iv=${iv}

Note: If you disable it, an empty initialization vector is used instead.
