How to integrate CAPTCHA

You can use captcha to avoid spam. The document below will guide you on how to integrate CAPTCHA into your site:

Adding to Contact Form 7

Using reCAPTCHA (recommended)

Update: 

Following this article: https://contactform7.com/recaptcha/

"reCAPTCHA v3 doesn’t need a CAPTCHA widget (the “I’m not a robot” checkbox used in reCAPTCHA v2) to work, so [recaptcha] form-tags are no longer necessary. If [recaptcha] form-tags are found in a form template, Contact Form 7 5.1 or higher ignores them and replaces them with an empty string." 

If you use the version 5.1 and higher, please make sure you use reCAPTCHA V3 also.

Step 1: Get the keys
