];
```

--------------------------------

### Publish posthog-config

Source: https://github.com/jeffersongoncalves/laravel-posthog/blob/main/README.md

### Fetch insights and session recordings

Source: https://github.com/jeffersongoncalves/laravel-posthog/blob/main/README.md

Fetch insights and session recordings. insights returns all insights, while sessionRecordings accepts an optional array of parameters such as 'limit'.

```php
$insights = PostHog::insights();

$recordings = PostHog::sessionRecordings(['limit' => 20]);
```

--------------------------------

### Capture an event with PostHog facade

Source: https://github.com/jeffersongoncalves/laravel-posthog/blob/main/README.md

Use the PostHog facade to capture a custom event with a distinct user ID and optional properties. The event name and properties are passed as arguments.

```php
use JeffersonGoncalves\PostHog\Facades\PostHog;

PostHog::capture('signup_completed', 'user_123', [
    'plan' => 'pro',
    '$current_url' => 'https://example.com/signup',
]);
```

--------------------------------

### Run tests with composer test

Source: https://github.com/jeffersongoncalves/laravel-posthog/blob/main/README.md

Runs the test suite for the package using Composer's test script.

```bash
composer test
```

--------------------------------

### Configure PostHog credentials in .env

Source: https://github.com/jeffersongoncalves/laravel-posthog/blob/main/README.md

Set your PostHog credentials in your .env file. POSTHOG_PROJECT_API_KEY is the public write-only key needed for capture, batch, and feature flags. POSTHOG_PERSONAL_API_KEY and POSTHOG_PROJECT_ID are only required for read endpoints (persons, HogQL, insights, session recordings).

```env
POSTHOG_HOST=https://us.i.posthog.com
POSTHOG_PROJECT_API_KEY=phc_your_project_api_key
POSTHOG_PERSONAL_API_KEY=phx_your_personal_api_key
POSTHOG_PROJECT_ID=12345
```

--------------------------------

### Run HogQL query

Source: https://github.com/jeffersongoncalves/laravel-posthog/blob/main/README.md

Run a HogQL query against PostHog events. The query string is passed directly to the query method.

```php
$result = PostHog::query(
    'SELECT event, count() FROM events WHERE timestamp > now() - interval 7 day GROUP BY event ORDER BY count() DESC LIMIT 10'
);
```

--------------------------------

### Batch multiple events with PostHog

Source: https://github.com/jeffersongoncalves/laravel-posthog/blob/main/README.md

Batch multiple events in a single call to reduce API requests. Each event is an associative array with 'event' and 'distinct_id' keys.

```php
PostHog::batch([
    ['event' => 'pageview', 'distinct_id' => 'user_1'],
    ['event' => 'signup', 'distinct_id' => 'user_2'],
]);
```

--------------------------------

### Identify a user and alias anonymous session

Source: https://github.com/jeffersongoncalves/laravel-posthog/blob/main/README.md

Identify a user with properties and merge an anonymous session into the identified person using the alias method. The alias call links the anonymous ID to the identified user.

```php
PostHog::identify('user_123', [
    'email' => 'user@example.com',
    'plan' => 'pro',
]);

// Merge an anonymous session into an identified person
PostHog::alias('user_123', 'anon_abc');
```

--------------------------------

### Evaluate feature flags with PostHog

Source: https://github.com/jeffersongoncalves/laravel-posthog/blob/main/README.md

Evaluate feature flags for a user. featureFlags returns all flags, featureFlag returns a single flag's value (false, true, or variant key), and isFeatureEnabled returns a boolean where a variant counts as enabled.

```php
// Every flag evaluated for this person
$flags = PostHog::featureFlags('user_123');

// A single flag: false when off, true when on, the variant key when multivariate
$variant = PostHog::featureFlag('new-pricing', 'user_123');

// Simple boolean check (a variant counts as enabled)
if (PostHog::isFeatureEnabled('new-pricing', 'user_123')) {
    // Show new pricing
}
```

--------------------------------

### Fetch persons data

Source: https://github.com/jeffersongoncalves/laravel-posthog/blob/main/README.md

Retrieve person data for a given distinct ID using the persons method.

```php
$persons = PostHog::persons('user_123');
```

--------------------------------

### Handle PostHog API exceptions

Source: https://github.com/jeffersongoncalves/laravel-posthog/blob/main/README.md

Handle API errors by catching PostHogException. Any non-2xx response throws this exception, which exposes the decoded error body via errorBody().

```php
use JeffersonGoncalves\PostHog\Exceptions\PostHogException;

try {
    PostHog::persons('user_123');
} catch (PostHogException $e) {
    logger()->error($e->getMessage(), $e->errorBody());
}
```

--------------------------------

### Check group-based feature flag

Source: https://github.com/jeffersongoncalves/laravel-posthog/blob/main/README.md

Check a feature flag with group-based targeting by passing a groups map as the third argument. The groups map associates group type keys with group IDs.

```php
PostHog::isFeatureEnabled('beta-dashboard', 'user_123', ['company' => 'acme-inc']);
```
