This allows you to add a ReCaptcha to your form to further protect your site from spam and abuse. A captcha will be automatically applied to the form if several declined payments are processed on your form within a certain time frame, but the ReCaptcha allows you to verify that a human is processing on your form every time the form is submitted.
To add the ReCaptcha to your form, follow the simple steps below.
First, locate the submit button code (shown below).
<div id="submitButton"> <button class="btn btn-primary center-block" type="submit">Submit</button> </div>
Delete that code and replace it with the code below:
<div class="block-center margintop_25"> <form method="post" action=""> <div> [addReCaptcha] </div> <input type="submit" value="Submit" class="btn btn-primary"> </form> </div>
This will show the ReCaptcha and require the user to verify themselves before processing the form.
