# Developers

You can integrate Snaptcha validation into your code and add-ons easily. Use the template tag above or the following code to create a Snaptcha field:

```php
require_once PATH_THIRD.'snaptcha/ext.snaptcha'.EXT;
$Snaptcha = new Snaptcha_ext();
$field = $Snaptcha->snaptcha_field();
```

You can optionally set the security level to be used:

```php
$security_level = 1;   // 1=low, 2=medium, 3=high
$field = $Snaptcha->snaptcha_field($security_level);
```

Then use the following code to validate a form submission:

```php
require_once PATH_THIRD.'snaptcha/ext.snaptcha'.EXT;
$Snaptcha = new Snaptcha_ext();
$validated = $Snaptcha->snaptcha_validate();   // returns a boolean (true or false)
```

If you explicitly set the security level in the Snaptcha field then you should set it to the same value in the validate function:

```php
$security_level = 1;	// 1=low, 2=medium, 3=high
$validated = $Snaptcha->snaptcha_validate($security_level);
```

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.boldminded.com/snaptcha/docs/developers.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.
