How to Create a Webhook for Lead Form Extensions in Google Ads

Setting up a webhook for lead form extensions in Google Ads needs to be on your to-do list because it will notify you when you have a new lead. As you already know, it’s important to follow up on leads quickly because the longer you wait to contact a lead, the lower your chances are of converting them to a customer.

With the recent changes to Google Ads, users do not receive automatic notifications when they receive an ad unless they set up a webhook using the lead form generation extension. By following these step-by-step instructions, you will receive notifications every time you receive a new lead, and have the chance to follow up quickly to secure them as a customer. So, are you ready to get started?

How to Set up a Webhook for Google’s Lead Form Extension (and Increase Your Chances of Converting Leads)

Google-ads-Webhook-php

There are many ways of creating a webhook. However, our development team at Zigma Internet Marketing recommends creating a PHP webhook to be compatible with most websites  (i.e developed on WordPress on Apache or Nginx servers).

To add a webhook PHP file to your WordPress server:

  1. Go to your files manager or FTP and a create a file. Name it webhook.php, and save it on the root of your domain folder.
  2. Add the following PHP Webhook commands to webhook.php file to connect your WordPress server to Google Ads:

<?php

$Google_data = file_get_contents(“php://input”);

$decoded_data= json_decode($Google_data, true);

$pass=”Key Used in Form Extensions“;

if ( $pass == $decoded_data[“google_key”]){

$lead_id = $decoded_data[“lead_id”];

$campaign_id = $decoded_data[“campaign_id”];

$bodyemail .= “Name: ” . $decoded_data[“user_column_data”][0][“string_value”];

$bodyemail .= “<br>Phone: ”  . $decoded_data[“user_column_data”][1][“string_value”];

$bodyemail .= “<br>Email: ” . $decoded_data[“user_column_data”][2][“string_value”];

}

$bodyemail .= “<br>Campagin ID: “. $campaign_id;

$bodyemail .= “<br>lead ID: “. $lead_id;

//Change with your emails

$emailfrom = “your WordPress Email Address as sender“;

$emailto = “Your Email Address“;

$subject = “Google Ads | Lead form extension”;

$headers = “From: ” . $emailfrom . “\r\n”;

$headers .= “Reply-To: “. $emailfrom . “\r\n”; //Optional

$headers .= “MIME-Version: 1.0\r\n”;

$headers .= “Content-Type: text/html; charset=utf-8\r\n”;

@mail($emailto, $subject, $bodyemail, $headers);

}

?>

      4.  If it’s a service you are offering, choose “Get Quote” or choose other CTA that fits your business.
      5. Add a text for the extension. The copy will show on the ad, so create a short and engaging message encouraging users to opt in.
      6. Go to the form section, and add a headline to your form. This headline should encourage users to complete the form like, “Get 20% off on HVAC Repairs .” The title should be less than 30 characters long.
      7. Add your business name.
      8. Describe your service or product (and your differentiators) in 200 characters or less.
      9. Add your privacy policy URL from your website.
      10. Add a  submission message(describe what happens now, and what should the user expect).
      11. Choose an appropriate call-to-action (such as a download if you have a file ready for the user to download) or send them to your thank you page on the website by choosing “Visit Website.”
      12. Click on the  “Lead Delivery Option.”
      13. Enter the webhook.php URL (yourdomain.com/webhook.php).
      14. Enter the key you have in your webhook.php ($pass=”Key Used in Form Extensions”;).

 

How to Test and Troubleshoot the Lead Form Extension Webhook

If you have uploaded the webhook to your server and created a Lead Form Extension, click on “SEND TEST DATA” below the “Manage your leads with a webhook (optional)” section. Shortly after, you should receive a test email from Google Ads if the webhook was set up correctly. If you do not receive an email, check your junk and spam folders.

 

We recommend using a PHPMailer to ensure your emails are not flagged as spam.
