### Products and Prices

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

Demonstrates how to list, create, update, and archive products, and create prices using the Paddle facade.

```APIDOC
## Products and Prices

### Description
Use the Paddle facade to manage products and prices. Each method returns a dedicated resource class.

### Methods
- `Paddle::products()->list(array $filters)` - List products with optional filters.
- `Paddle::products()->create(array $attributes)` - Create a new product.
- `Paddle::products()->update(string $productId, array $attributes)` - Update an existing product.
- `Paddle::products()->archive(string $productId)` - Archive a product.
- `Paddle::prices()->create(string $productId, int $amount, string $currencyCode, string $description, array $attributes)` - Create a price for a product.

### Parameters
- `list()` accepts Paddle's filters: `status`, `after`, `per_page`, `order_by`, `id`, etc. Default `per_page` is `default_per_page`.
- `create()` for products requires `name` and `tax_category`.
- `amount` is in the lowest denomination (e.g., 1990 = US$ 19.90).

### Example
```php
use JeffersonGoncalves\Paddle\Facades\Paddle;

$products = Paddle::products()->list(['status' => 'active']);

$product = Paddle::products()->create([
    'name' => 'Pro Plan',
    'tax_category' => 'saas',
    'description' => 'Everything in one plan',
]);

Paddle::products()->update($product['data']['id'], ['name' => 'Pro Plan (annual)']);
Paddle::products()->archive($product['data']['id']);

$price = Paddle::prices()->create(
    productId: $product['data']['id'],
    amount: 1990,

### Manage transactions, discounts, and adjustments with Paddle facade

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

Create transactions, invoice them, create discounts, and create adjustments (refunds). The `transactions()->create()` method uses named arguments for items and attributes. The `discounts()->create()` method takes amount, type, description, and optional attributes. The `adjustments()->create()` method requires a transaction ID, action, reason, and items.

```php
$transaction = Paddle::transactions()->create(
    items: [['price_id' => 'pri_123', 'quantity' => 1]],
    attributes: ['customer_id' => 'ctm_123', 'collection_mode' => 'manual'],
);

Paddle::transactions()->invoice($transaction['data']['id']);

Paddle::discounts()->create(25, 'percentage', 'Launch', ['code' => 'LAUNCH25']);

// Refund a transaction item
Paddle::adjustments()->create(
    transactionId: $transaction['data']['id'],
    action: 'refund',
    reason: 'Customer request',
    items: [['item_id' => 'txnitm_123', 'type' => 'full']],
);
```

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

### Manage customers with Paddle facade

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

Create, update, retrieve credit balances, and archive a customer. The `create()` method takes an email and an optional attributes array. The `creditBalances()` method retrieves the customer's credit balances.

```php
$customer = Paddle::customers()->create('jane@example.com', ['name' => 'Jane Doe']);

Paddle::customers()->update($customer['data']['id'], ['name' => 'Janet Doe']);
Paddle::customers()->creditBalances($customer['data']['id']);

### Manage products and prices with Paddle facade

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

Manage products and prices via the Paddle facade. The `list()` method accepts Paddle filters like `status` and defaults `per_page` to `default_per_page`. The `create()` method for products requires `name` and `tax_category`; missing fields throw `InvalidArgumentException` before any HTTP call. The `prices()->create()` method uses named arguments and expects the amount in the lowest denomination (e.g., 1990 for US$ 19.90).

```php
use JeffersonGoncalves\Paddle\Facades\Paddle;

$products = Paddle::products()->list(['status' => 'active']);

$product = Paddle::products()->create([
    'name' => 'Pro Plan',
    'tax_category' => 'saas',
    'description' => 'Everything in one plan',
]);

Paddle::products()->update($product['data']['id'], ['name' => 'Pro Plan (annual)']);
Paddle::products()->archive($product['data']['id']);

$price = Paddle::prices()->create(
    productId: $product['data']['id'],
    amount: 1990,            // lowest denomination — 1990 = US$ 19.90
    currencyCode: 'USD',
    description: 'Monthly',
    attributes: ['billing_cycle' => ['interval' => 'month', 'frequency' => 1]],
);
```

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

### Set Paddle environment variables

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

Shows the environment variables for Paddle credentials. CREATE the API key under Developer Tools > Authentication. Note that sandbox and live keys are separate, and a sandbox key only works when PADDLE_SANDBOX is true.

```bash
PADDLE_API_KEY=your-api-key
PADDLE_SANDBOX=false
PADDLE_WEBHOOK_SECRET=your-notification-secret
```

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

### Webhooks

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

Demonstrates how to verify webhook signatures and handle incoming webhook requests.

```APIDOC
## Webhooks

### Description
Verify the `Paddle-Signature` header against the raw request body before trusting a webhook.

### Methods
- `Paddle::webhooks()->verifyRequest(Request $request)` - Verify the webhook request signature.
- `Paddle::webhooks()->verify(string $payload, string $signature, int $maxAge = 5)` - Verify a raw payload and signature. Signatures older than `$maxAge` seconds are rejected (pass `0` to disable).

### Parameters
- `$payload` must be the raw body; a re-encoded array will not match.

### Example
```php
use Illuminate\Http\Request;
use JeffersonGoncalves\Paddle\Facades\Paddle;

Route::post('/paddle/webhook', function (Request $request) {
    abort_unless(Paddle::webhooks()->verifyRequest($request), 403);

    $event = $request->json()->all();

    // handle $event['event_type'] ...

    return response()->noContent();
})->withoutMiddleware([VerifyCsrfToken::class]);
```
```

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

### Publish the Paddle config file

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

Runs the Artisan vendor:publish command to publish the package's configuration file. This is required to configure the package credentials.

```text
php artisan vendor:publish --tag=paddle-config
```

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

### Paddle configuration file

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

This is the config/paddle.php configuration file. It reads the API key, sandbox flag, webhook secret, and default per-page limit from environment variables. The base URL defaults to the sandbox or live API depending on the PADDLE_SANDBOX variable, and can be overridden with PADDLE_BASE_URL.

```php
// config/paddle.php
return [
    'api_key' => env('PADDLE_API_KEY'),
    'sandbox' => (bool) env('PADDLE_SANDBOX', false),
    'base_url' => env('PADDLE_BASE_URL', env('PADDLE_SANDBOX', false)
        ? 'https://sandbox-api.paddle.com'
        : 'https://api.paddle.com'),
    'webhook_secret' => env('PADDLE_WEBHOOK_SECRET'),
    'default_per_page' => env('PADDLE_DEFAULT_PER_PAGE', 50),
];
```

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

### Manage subscriptions with Paddle facade

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

List, update, cancel, pause, resume, activate, charge, and update payment method for subscriptions. The `cancel()` method without a second argument cancels at period end; passing `'immediately'` cancels immediately. The `pause()` method accepts an optional timestamp; omitting it pauses indefinitely. The `activate()` method moves a subscription from trialing to active.

```php
$subscriptions = Paddle::subscriptions()->list(['customer_id' => 'ctm_123']);

Paddle::subscriptions()->update('sub_123', [
    'proration_billing_mode' => 'prorated_immediately',
    'items' => [['price_id' => 'pri_123', 'quantity' => 3]],
]);

Paddle::subscriptions()->cancel('sub_123');                         // at period end
Paddle::subscriptions()->cancel('sub_123', 'immediately');
Paddle::subscriptions()->pause('sub_123', '2026-12-01T00:00:00Z');  // omit to pause indefinitely
Paddle::subscriptions()->resume('sub_123');
Paddle::subscriptions()->activate('sub_123');                       // trialing -> active

// One-off charge on top of the subscription
Paddle::subscriptions()->charge('sub_123', [['price_id' => 'pri_123', 'quantity' => 1]], 'immediately');

// Transaction that lets the customer update their card
Paddle::subscriptions()->updatePaymentMethodTransaction('sub_123');
```

### Error Handling

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

Demonstrates how to catch and handle PaddleException and InvalidArgumentException.

```APIDOC
## Error Handling

### Description
Any non-2xx API response throws `JeffersonGoncalves\Paddle\Exceptions\PaddleException`, which exposes the decoded error body and Paddle's machine-readable code. Missing required fields throw `InvalidArgumentException` before any HTTP call.

### Methods
- `PaddleException::errorCode()` - Get the machine-readable error code.
- `PaddleException::errorBody()` - Get the decoded error body.

### Example
```php
use JeffersonGoncalves\Paddle\Exceptions\PaddleException;

try {
    Paddle::subscriptions()->get('sub_missing');
} catch (PaddleException $e) {
    if ($e->errorCode() === 'entity_not_found') {
        // ...
    }

    logger()->error($e->getMessage(), $e->errorBody());
}
```
```

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

### Verify Paddle webhook signature with verifyRequest

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

Handle a Paddle webhook by verifying the `Paddle-Signature` header against the raw request body. The `verifyRequest()` method returns a boolean; if false, the request is aborted with a 403. The route must exclude the CSRF middleware. The `verify()` method is also available for raw payloads, with a `$maxAge` parameter (default 5 seconds) to reject old signatures.

```php
use Illuminate\Http\Request;
use JeffersonGoncalves\Paddle\Facades\Paddle;

Route::post('/paddle/webhook', function (Request $request) {
    abort_unless(Paddle::webhooks()->verifyRequest($request), 403);

    $event = $request->json()->all();

    // handle $event['event_type'] ...

    return response()->noContent();
})->withoutMiddleware([VerifyCsrfToken::class]);
```

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

### Handle Paddle API errors with PaddleException

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

Catch `PaddleException` for non-2xx API responses. The exception exposes the decoded error body via `errorBody()` and Paddle's machine-readable code via `errorCode()`. Missing required fields (e.g., `name`/`tax_category` on `products()->create()`) throw `InvalidArgumentException` before any HTTP call.

```php
use JeffersonGoncalves\Paddle\Exceptions\PaddleException;

try {
    Paddle::subscriptions()->get('sub_missing');
} catch (PaddleException $e) {
    if ($e->errorCode() === 'entity_not_found') {
        // ...
    }

    logger()->error($e->getMessage(), $e->errorBody());
}
```

=== COMPLETE CONTENT === This response contains all available snippets from this library. No additional content exists. Do not make further requests.
