To implement reCAPTCHA v3 on your Webflow site, you'll need to follow these steps:
Step 1: Generate reCAPTCHA v3 API Keys
Visit the reCAPTCHA admin website (https://www.google.com/recaptcha/admin) and sign in with your Google account. If you don't have an account, you'll need to create one.
Once signed in, click on the "+ button" to add a new site. Enter your site name, select reCAPTCHA v3, and enter the domain(s) where you'll be implementing reCAPTCHA on your Webflow site. Click on the "Submit" button to generate your API keys.
Take note of the "Site key" and "Secret key" as you'll need them in the next steps.
Step 2: Add reCAPTCHA Script to Webflow Project
In your Webflow project, go to Project Settings > Custom Code.
In the "Head Code" section, paste the following code snippet:
```
```
Replace "YOUR_SITE_KEY" with the reCAPTCHA site key you obtained in Step 1.
Step 3: Add Custom Code to Webflow Pages
Next, you'll need to add the custom code that will trigger the reCAPTCHA verification on your Webflow pages.
Navigate to the page where you want to implement reCAPTCHA and go to Page Settings > Custom Code. In the "Before
" section, paste the following code:
```
```
Replace "YOUR_SITE_KEY" with your reCAPTCHA site key obtained in Step 1. You can also customize the `action` parameter to suit your needs. Remember to implement your server-side verification logic within the `.then()` callback.
Step 4: Build Server-Side Verification Logic
On the server-side, you'll need to verify the reCAPTCHA token received from the client to ensure the requests are not generated by bots.
How you implement this verification depends on your server technology stack. Google provides official libraries and documentation for various programming languages, including PHP, Node.js, Python, Java, etc.
Choose your preferred programming language and follow the reCAPTCHA documentation to validate the token by sending a request to the reCAPTCHA server.
Once verified, you can proceed with your desired logic, such as submitting a form or allowing access to certain protected content.
That's it! You've successfully implemented reCAPTCHA v3 on your Webflow site. Remember to thoroughly test your implementation to ensure it's working as expected and effectively preventing unwanted bot activity.
