# Set up Google reCaptcha

Google reCAPTCHA protects your Registration Form from spam and bot sign-ups. Your **Site key** and **Secret key** are entered once in **Settings > General > Google reCaptcha**, then enabled per form.

{% hint style="info" %}

* To generate your keys, see [Set up Google reCaptcha v2/v3 Site Key and Secret Key](/samita-wholesale-b2b/registration-form/set-up-google-recaptcha-v2-v3-site-key-and-secret-key.md).
* To turn reCAPTCHA on for a specific Registration Form, see [Add reCaptcha to the form](/samita-wholesale-b2b/registration-form/add-recaptcha-to-the-form.md).
  {% endhint %}

## What's the difference between reCAPTCHA v2 and v3?

{% columns %}
{% column %}
**reCAPTCHA v2**

Asks the customer to click the "I'm not a robot" checkbox, and may show an image-recognition challenge.
{% endcolumn %}

{% column %}
**reCAPTCHA v3**

Runs silently in the background and scores the customer's behavior — the higher the score, the more likely they're human. Customers never see a challenge.
{% endcolumn %}
{% endcolumns %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.samita.io/samita-wholesale-b2b/setting/set-up-google-recaptcha.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
