Commet PHP SDK
==============

[](#commet-php-sdk)

Billing and usage tracking for SaaS applications.

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

[](#installation)

```
composer require commet/commet-php
```

Quick start
-----------

[](#quick-start)

```
use Commet\Commet;

$commet = new Commet(apiKey: 'ck_xxx', environment: 'production');

// Create a customer
$commet->customers->create(email: 'user@example.com', externalId: 'user_123');

// Create a subscription
$commet->subscriptions->create(externalId: 'user_123', planCode: 'pro');

// Track usage
$commet->usage->track(feature: 'api_calls', externalId: 'user_123');

// Track AI token usage
$commet->usage->track(
    feature: 'ai_generation',
    externalId: 'user_123',
    model: 'claude-sonnet-4-20250514',
    inputTokens: 1000,
    outputTokens: 500,
);
```

Customer context
----------------

[](#customer-context)

Scope all operations to a customer to avoid repeating `externalId`:

```
$customer = $commet->customer('user_123');

$customer->usage->track('api_calls');
$customer->features->check('custom_branding');
$customer->seats->add('editor', count: 3);
$customer->portal->getUrl();
```

Webhook verification
--------------------

[](#webhook-verification)

```
use Commet\Webhooks;

$webhooks = new Webhooks();

$payload = $webhooks->verifyAndParse(
    rawBody: $requestBody,
    signature: $_SERVER['HTTP_X_COMMET_SIGNATURE'] ?? null,
    secret: 'whsec_xxx',
);

if ($payload === null) {
    throw new \RuntimeException('Invalid webhook signature');
}

if ($payload['event'] === 'subscription.activated') {
    // handle activation
}
```

Environments
------------

[](#environments)

The SDK defaults to `sandbox`. Set `environment: 'production'` for live operations:

```
$commet = new Commet(apiKey: 'ck_xxx', environment: 'production');
```
