A Guide to Integrating Google re-Captcha in Power Pages

As we know, Google’s re-CAPTCHA service incorporates various mechanisms, including advanced risk analysis and adaptive challenges, to differentiate between legitimate users and potential bots or malicious actors. By analysing user behaviour and various risk factors, captcha aims to provide a seamless experience for genuine users while effectively blocking automated bots and other abusive activities on websites.

This approach helps protect websites from a wide range of abusive behaviours, including spamming contact forms, creating fake accounts, performing fraudulent transactions, and other malicious activities. It enhances the overall security and integrity of online platforms, allowing legitimate users to interact with websites without unnecessary interruptions while thwarting potential threats posed by automated scripts or bots.

Recently, we had a client requirement where the client had mandated the integration of Google re-CAPTCHA into Power Pages, replacing the Out-of-the-Box (OOB) solution. This shift marks a pivotal moment in ensuring robust protection against malicious activities while streamlining user interactions. This blog outlines the systematic process of integrating Google re-CAPTCHA seamlessly into Power Pages, thereby fortifying the security framework and elevating user engagement.

Step 1:

Firstly, to integrate the Google re-CAPTCHA, we need the site key. So, to get the site key, we have to register our site using this link. Add the domain name in the highlighted part.

Once you add the domain, click on the ‘submit’ button, and you will be redirected to the page where you will be able to see the ‘site key’. Refer to the below screenshot

Step 2:

Now to add the Google re-CAPTCHA to our portal, we have to write some HTML code.

In this, we have taken 2 input fields and one div with id – ‘HTML-element’ in which our Google re-CAPTCHA will be visible.

Step 3:

Add this link to your HTML.

Step 4:

Now add the given onload function to the JavaScript file.

Step 5:

Now, when we click on “I’m not a robot,” we will get to see this type of puzzle.

Step 6:

This code will create the contact when it gets the response from the captcha. If there is no response from the captcha, then it will throw a pop-up message to fill the captcha.

As you can see in the above image, the captcha is not clicked, so it will give an error message in the pop-up.

Note: This validation pop-up is a custom modal created using HTML, CSS, and JS.

Once all the fields are filled out, the contact with the given first and last name will be created.
