Setting Up Cloudflare Turnstile

Would you like to use Cloudflare Turnstile to help prevent spam submissions in your WordPress forms? Cloudflare Turnstile is a free, CAPTCHA-like alternative that offers a user-friendly experience by confirming visitors are real humans without showing them any puzzles.

This tutorial will show you how to set up and use Cloudflare Turnstile with WPForms.

Cloudflare turnstile overview


Before you get started, ensure WPForms is installed and activated on your WordPress site.

Generating Cloudflare Turnstile API Keys

To start, log in to your WordPress admin area and go to WPForms » Settings. Then click on the CAPTCHA tab.

WPForms CAPTCHA settings

To configure Cloudflare Turnstile, select the Turnstile option.

Select Turnstile option

Once selected, additional settings will appear. You’ll need to generate a set of API keys from your Cloudflare account to connect it with WPForms. Leave this browser tab open and proceed to the next step.

Adding Your Site in Cloudflare

To begin, you’ll need to log in to your Cloudflare account. Once you’ve logged in, select the Turnstile menu and click on Add site.

Click add site button

Next, you’ll see an option to enter your Site name. This name is for internal use only to help you identify widgets on your Cloudflare account.

Enter site name

After that, enter your website address in the Domain field.

Enter website domain

Note: You can add multiple websites in the Domain field. This allows you to use one set of API keys on multiple websites.

Under Widget Type, you’ll need to choose how Cloudflare should process CAPTCHA requests on your forms. Below are the available options:

Select widget type

  • Managed: This option allows Cloudflare to decide whether to show an interactive challenge or automatically verify the user based on their browser data and interaction.
  • Non-interactive: This option will show the CAPTCHA widget on your website’s frontend. However, it doesn’t require user interaction. Cloudflare will automatically run the challenge and verify the user.
  • Invisible: This option runs in the background and requires no interaction from the user.

After choosing your widget type, click the Create button to add your site.

Click the create button

This would generate a unique set of API keys for your website.

Cloudflare site key and secret key

You’ll need to copy the Site Key and Secret Key from Cloudflare. Then head back to your WPForms settings page, and paste each key into its corresponding field.

Once you’ve added both keys, proceed to configure additional settings for the Cloudflare Turnstile CAPTCHA.

Configuring Additional Settings

Below the Secret Key, you’ll find the option to update the Fail Message. This is the message displayed when a user attempts to submit a form without completing the Cloudflare Turnstile verification challenge.

Configure fail message

Next, choose the style you’d like the widget to use from the Type dropdown. Available options are: Auto, Light, and Dark.

Select Captcha type

Note: Using the default Auto mode for your widget will toggle between Light and Dark mode depending on the user’s device settings.

After choosing the CAPTCHA type, you’ll find the No-Conflict Mode settings. If Cloudflare Turnstile is being loaded more than once on your site (for example, by both WPForms and your WordPress theme), this can prevent the Turnstile CAPTCHA from working properly.

Preview and no-conflict mode

No-Conflict Mode will remove any Cloudflare Turnstile code that’s not loaded by WPForms. However, we highly recommend getting in touch with our support team if you’re at all unsure whether to use this option.

Next, you’ll see the Preview section. This shows how the CAPTCHA widget will look on your website’s frontend.

Note: You’ll need to save your settings before you can see a preview of the widget.

When you’re ready, go ahead and click the Save Settings button.

Click save settings button

After saving your settings, you should see a preview of the Cloudflare Turnstile widget.

Adding Cloudflare Turnstile to a Form

Now that you’ve set up your keys, you’ll be able to enable Cloudflare Turnstile on any of your forms.

For this, go ahead and create a new form or edit an existing one to access the form builder. Next, look under Standard Fields and select the Turnstile field.

Adding Turnstile to a form

Alternatively, you can always enable or disable Cloudflare Turnstile for a form by going to Settings » Spam Protection and Security in the form builder.

Spam protection and security settings

Under the Protection section, you can enable the Store spam entries in the database option if you’d like to review spam entries before deleting them from the entries page.

Store spam entries in the database option

Enabling this option allows all submissions, including those flagged as spam by Cloudflare Turnstile.

Note: The Enable minimum time to submit option helps prevent bot submissions by setting a minimum time before submissions are allowed on the form. See our spam prevention guide for more details.

Next, scroll down to the CAPTCHA section and toggle the Enable Cloudflare Turnstile option to the on position.

Enabling Cloudflare Turnstile in the spam protection settings

To confirm that Cloudflare Turnstile is enabled, look for the Turnstile badge in the upper right corner of the form builder.

Note: If no badge appears in your form builder, ensure you’ve correctly set up your Cloudflare Turnstile API keys.

Testing Cloudflare Turnstile

The last step is to run a quick test to ensure that Cloudflare Turnstile looks and works how you expect.

To test it out, you’ll simply need to submit an entry to your form. For more details on how to test out your forms, please check our full form testing checklist.

Viewing Spam Entries

If you enabled the spam entry storage option, you’ll be able to view entries identified as spam from the Entries page.

There is also an option to recover entries that may have been mistakenly flagged as spam by Cloudflare Turnstile.
