mason/captcha
=============

[](#masoncaptcha)

Unified captcha verification for Laravel. One Manager-based API in front of Google reCAPTCHA v2 (checkbox and invisible), reCAPTCHA v3, hCaptcha, and Cloudflare Turnstile — switch providers by changing config, not code.

> **Status**: reCAPTCHA v2 is fully supported (backend verification, validation rule, middleware, and the `` widget). Backend verification for reCAPTCHA v3, hCaptcha, and Turnstile is implemented; their frontend widgets are coming in a later release.

Requirements
------------

[](#requirements)

- PHP 8.2+ (Laravel 13 requires PHP 8.3+)
- Laravel 12 / 13

Installation
------------

[](#installation)

```
composer require zhang-mason/laravel-captcha-kit
```

Publish the config file if you need to customise it:

```
php artisan vendor:publish --tag=captcha-config
```

Set your keys in `.env`:

```
CAPTCHA_DRIVER=recaptcha_v2
RECAPTCHA_V2_SITE_KEY=your-site-key
RECAPTCHA_V2_SECRET_KEY=your-secret-key
RECAPTCHA_V2_MODE=checkbox # or: invisible
```

Usage
-----

[](#usage)

### Frontend

[](#frontend)

Render the widget inside your form. The script tag is included automatically and deduplicated across multiple widgets.

```

    @csrf

    Send

```

In `invisible` mode the widget binds to its surrounding form (or pass `form="form-id"`) and submits automatically once the challenge completes.

### Validation rule

[](#validation-rule)

```
use Mason\Captcha\Rules\CaptchaRule;

public function rules(): array
{
    return [
        'g-recaptcha-response' => ['required', new CaptchaRule],
        // Target a specific driver:
        'cf-turnstile-response' => ['required', CaptchaRule::driver('turnstile')],
        // reCAPTCHA v3 with an expected action:
        'g-recaptcha-response' => ['required', CaptchaRule::driver('recaptcha_v3')->action('login')],
    ];
}
```

### Middleware

[](#middleware)

```
Route::post('/contact', ContactController::class)->middleware('captcha');
Route::post('/login', LoginController::class)->middleware('captcha:recaptcha_v3,login');
```

Failed verifications throw a `ValidationException` (HTTP 422 for JSON requests, redirect back with errors otherwise).

### Facade

[](#facade)

```
use Mason\Captcha\Facades\Captcha;

$result = Captcha::verify($request->input('g-recaptcha-response'), $request->ip());

if ($result->failed()) {
    abort(422);
}

// A specific driver:
$result = Captcha::driver('turnstile')->verify($token, $ip);

// reCAPTCHA v3 exposes the score:
$result = Captcha::driver('recaptcha_v3')->verify($token, $ip);
$result->score;    // e.g. 0.9
$result->passed(); // success AND score >= configured threshold
```

`verify()` returns a `VerificationResult` with `success`, `score`, `action`, `hostname`, `challengedAt`, `errorCodes`, and the `raw` provider response. Use `passed()` / `failed()` — they also apply the v3 score threshold.

### Custom drivers

[](#custom-drivers)

```
use Mason\Captcha\Facades\Captcha;

Captcha::extend('my_provider', fn ($app) => new MyProviderDriver(/* ... */));
```

### Testing

[](#testing)

```
use Mason\Captcha\Facades\Captcha;

public function test_contact_form(): void
{
    Captcha::fake(); // every verification passes, no HTTP

    $this->post('/contact', [/* ... */])->assertOk();

    Captcha::fake()->assertVerified();
}

Captcha::fake()->failing();     // every verification fails
Captcha::fake()->scoring(0.3);  // simulate a v3 score
```

You can also skip verification entirely per environment via `captcha.skip_environments` (defaults to `['testing']`).

Configuration notes
-------------------

[](#configuration-notes)

- **Fail-closed by default**: if the provider's siteverify endpoint is unreachable, verification fails. Set `CAPTCHA_ON_FAILURE=pass` to fail open instead.
- reCAPTCHA v2 checkbox vs. invisible is a frontend-only difference — both use the same driver; switch with `RECAPTCHA_V2_MODE`.

Development
-----------

[](#development)

```
composer install
composer test  # pest
composer lint  # pint
```
