Google reCAPTCHA V2 helps determine whether a CRM form is being filled out by a real customer or an automated bot. In Bitrix24, you can enable invisible reCAPTCHA V2, which analyzes customer behavior on the site, such as mouse movements, page scrolling speed, time spent, and other parameters. If suspicious activity is detected, the customer will be prompted for additional verification, like selecting all images with specific objects.

Create and configure CRM form

In this article:

Connect the reCAPTCHA V2 module

1. Go to the CRM section > Add-ons > CRM forms and open the desired form.
2. Click Expert mode to view all CRM form settings.
3. Go to the Spam protection section.
4. Select Invisible and click Save.
5. Ensure the form displays the "reCAPTCHA spam protection" icon.

Add reCAPTCHA V2 keys

Obtain keys. Open the Google reCAPTCHA admin page and sign in with your Google account. Fill out the form to get the keys for free.

• Label. Enter your site or project name. This helps find the right keys if you connect the module to multiple sites.


• reCAPTCHA type. Select Invisible reCAPTCHA badge (V2).


• Domains. Enter two domain names: your site and CRM form. Copy them from the address bar and paste them into the fields without https.

Once you complete the form, click Submit. You'll then be directed to a page with a pair of keys. Copy them.

Add keys to the CRM form. Return to the form settings in Bitrix24 and click Edit keys. Fill in the fields:

• Key — site key
• Secret — secret key

Save the changes. The keys will be valid for all CRM forms.

Check reCAPTCHA functionality. Fill out and submit the CRM form. View the results on the Google reCAPTCHA admin page. If the report doesn't appear, wait a few hours.

If the module blocks form submissions from customers, adjust the reCAPTCHA sensitivity.

1. Open Settings (⚙️).
2. Move the slider in the "Security settings" section to the beginning or middle of the range.
