NOTICE: This plugin will no longer be supported nor updated. Infusionsoft has now added Google’s reCaptcha into their forms natively, so this plugin is no longer needed.
Infusionsoft® has a native captcha you can insert into web forms, but it’s not user-friendly, blocks submissions, and is ugly. With the new reCAPTCHA API, Google has released a captcha that the bulk of your users will only have to check a box to pass, optimizing opt-ins while protecting you from inserting spam into your Infusionsoft automation.
As a bonus, activating this plugin in an Infusionsoft web form will also set up basic HTML5 form validation for it.
Requires PHP 5.2+ for json support
