Adding CAPTCHA for public (published) forms is crucial as it protects the form from unwanted or automatic submissions using bots or spam services. It acts as an additional layer of security ensuring only real users submit the form.
Steps to configure CAPTCHA in published forms
In the Customize form slider, tick the checkbox beside Enable CAPTCHA under Form Properties. The Enable CAPTCHA pop-up will appear.
Choose the type of CAPTCHA you want to use:
Zoho Creator CAPTCHA - An alpha-numeric captcha provided by Zoho Creator that the user must enter for verification. For example, WAG63P.
I'm not a robot checkbox (v2 Google reCAPTCHA) - Prompts users to confirm the I'm not a robot checkbox. This is provided by Google reCAPTCHA.
Invisible reCAPTCHA badge - Prompts users to check the I'm not a robot checkbox only if suspicious activity is detected. This is provided by Google reCAPTCHA.
If option a is chosen, you can skip to step 5. If option b and c, you need to configure two keys (site key and secret key) by signing in to Google. The site key is used to trigger the reCAPTCHA service and secret key authorizes the connection and verifies the responses.
To get the keys for reCAPTCHA:
Sign in to your Google account.
Register Creator domain in Google reCaptcha by following the below steps.
Enter a label for reference.
Click the captcha type Challenge (v2) and select the type under it.
Enter the domain name under Domains according to your Creator DC(refer to image below) and click Submit.
Copy the secret and site keys from your Google account and paste them into your Creator's Enable CAPTCHA pop-up.
Choose the Language from the list. Select Theme for the CAPTCHA, which will be applied only to the CAPTCHA in the form.
Click Save. This adds the selected Captcha to the published form.
Note:
If the form already has a CAPTCHA field, the published form's CAPTCHA will override it.
CAPTCHA is not supported if the form is embedded using the downloaded HTML/CSS.
Keys will not be retained when options are changed. You need to get the keys from Google and add them again. If you've deleted the keys from Google, you will need to generate them again.
Refer to the below table if you see an error in the published form.
