README

A comprehensive Laravel package for interacting with the Gumroad API. This package provides full support for all Gumroad API endpoints with constructor-based Laravel Data DTOs, QueryBuilders, and Laravel integration.

Built with Spatie Laravel Data featuring constructor-based instantiation for improved type safety and immutability.

Features

• ✅ Full API coverage for all Gumroad endpoints
• ✅ Constructor-based Laravel Data DTOs with type safety and immutability
• ✅ Fluent QueryBuilder classes for complex queries
• ✅ Laravel Service Provider and Facade integration
• ✅ Proper exception handling
• ✅ PSR-4 autoloading
• ✅ Comprehensive documentation
• ✅ Automatic array-to-DTO conversion utilities
• ✅ Backward compatibility with factory methods

Installation

composer require serenity_technologies/gumroad

Configuration

Publish the configuration file:

php artisan vendor:publish --provider="Gumroad\GumroadServiceProvider" --tag=config

Add your Gumroad access token to your .env file:

GUMROAD_ACCESS_TOKEN=your_gumroad_access_token_here

Usage

Using the Facade

use Gumroad\Facades\Gumroad;

// Get all products
$products = Gumroad::getAllProducts();

// Get a specific product
$product = Gumroad::getProduct('product-id-here');

// Create a new offer code using constructor
$offerCodeData = new CreateOfferCodeDTO(
    name: 'SPRING20',
    amount_off: null,
    percent_off: 20,
    offer_type: 'percent',
    max_purchase_count: null,
    universal: null
);

$offerCode = Gumroad::createOfferCode('product-id', $offerCodeData);

Using Dependency Injection

use Gumroad\Clients\GumroadClient;

class ProductService 
{
    public function __construct(private GumroadClient $gumroad) {}
    
    public function getAllProducts()
    {
        return $this->gumroad->getAllProducts();
    }
}

Query Builders

Sales Query Builder

use Gumroad\QueryBuilders\SalesQueryBuilder;

$query = (new SalesQueryBuilder())
    ->after('2023-01-01')
    ->before('2023-12-31')
    ->productId('product-id')
    ->email('[e-mail]')
    ->build();

$sales = Gumroad::getSales($query);

Subscribers Query Builder

use Gumroad\QueryBuilders\SubscribersQueryBuilder;

$query = (new SubscribersQueryBuilder())
    ->email('[e-mail]')
    ->paginated(true)
    ->pageKey('next-page-key')
    ->build();

$subscribers = Gumroad::getActiveSubscribers('product-id', $query);

DTO Usage

Constructor-Based Approach (Recommended)

use Gumroad\DTOs\CreateOfferCodeDTO;
use Gumroad\DTOs\VerifyLicenseDTO;

// Create offer code with named parameters
$offerCode = new CreateOfferCodeDTO(
    name: 'WELCOME10',
    amount_off: null,
    percent_off: 10,
    offer_type: 'percent',
    max_purchase_count: 100,
    universal: null
);

// Verify license
$license = new VerifyLicenseDTO(
    product_id: 'product-123',
    license_key: 'ABC123-DEF456',
    increment_uses_count: true
);

Factory Method Approach (Backward Compatible)

use Gumroad\DTOs\CreateOfferCodeDTO;

// Create from array data
$offerCode = CreateOfferCodeDTO::fromArray([
    'name' => 'BACKWARD20',
    'amount_off' => null,
    'percent_off' => 20,
    'offer_type' => 'percent',
    'max_purchase_count' => 50,
    'universal' => null
]);

DTO to Array Conversion

use Gumroad\DTOs\ProductDTO;

// Convert DTO to array
$productDto = new ProductDTO(/* ... */);
$arrayData = $productDto->toArray();

Error Handling

All API errors are wrapped in GumroadException:

use Gumroad\Exceptions\GumroadException;

try {
    $product = Gumroad::getProduct('invalid-id');
} catch (GumroadException $e) {
    echo "API Error: " . $e->getMessage();
}

Testing

composer test

# Full-featured converter with logging
php convert_dtos_to_constructors.php
