To securely identify users, you must sign their email address using your private workspace secret key. This ensures that only users you authorize can access your Messenger widget with their information.

PHP Example

Here’s how to generate the HMAC signature in PHP:

{{ hash_hmac("sha256", auth()->user()->email, "YOUR_SECRET_KEY_HERE") }}

Add your generated Hash to Messenger SDK

<script>
  window.$pipeback = {
    user: {
      id: "userId",
      name: "userName",
      email: "userEmail",
      signature: "generatedHash"
    }
  };
</script>
