Custom hCaptcha Page Guide

The following document outlines how to create a custom CAPTCHA page for use with Netacea’s hCAPTCHA solution.

Prerequisites

Please ensure that Netacea has configured and enabled CAPTCHA for your account. Also, ensure that the standard CAPTCHA page has been tested and can be served before implementing a custom CAPTCHA page.

Provided that the above prerequisites have been completed, a custom CAPTCHA page can be created by doing the following:

HTML Page

To create an HTML page that will be used for serving CAPTCHA it may be beneficial to start with the Netacea Template HTML before adding the custom HTML code. The templated page can be seen at the bottom of this document. Your custom HTML page can be designed per your specific requirements and/or company branding, however, the page must include the following code. The following scripts should be within the document head element (<head>...</head>):

<link rel="stylesheet" href="https://assets.ntcacdn.net/Mitigations/captcha-1.0.0.css"/>
<script src="https://js.hcaptcha.com/1/api.js" async defer></script>

In addition, include the following code somewhere within the body (<body>...</body>):

<form id="frmCaptcha" action="" method="POST">
    <div
        class="h-captcha"
        data-sitekey="{{CAPTCHA_SITE_KEY}}"
        data-callback="showButton"
    ></div>
    <br />
    <br /><input type="submit" value="Submit" class="btn btnHidden" /><input
        type="hidden"
        maxlength="40"
        id="hitid"
        name="hitid"
        value="{{TRACKING_ID}}"
    />
</form>

The below scripts must also be added at the end of, but still within the body (<body>...</body>):

<script src="https://assets.ntcacdn.net/Mitigations/fetch-polyfill-3.6.2.js"></script>
<script src="https://assets.ntcacdn.net/Mitigations/submit-hcaptcha-2.0.2.js"></script>

Please note that certain links within the CAPTCHA page may not work if they are hosted behind the site that is being protected by Netacea.
