Shopify App Development Tutorial with Laravel

Introduction In the realm of e-commerce, Shopify has become a dominant player due to its user-friendly platform and robust functionality. For developers looking to extend Shopify's capabilities, creating custom apps is a valuable skill. Laravel, a popular PHP framework, is a great choice for building these applications due to its elegant syntax and powerful features. This tutorial will guide you through the process of developing a Shopify app using Laravel, covering everything from setting up your development environment to deploying your app.

Prerequisites Before diving into the development process, ensure you have the following prerequisites:

  1. Basic understanding of PHP and Laravel.
  2. Familiarity with Shopify’s API and app development concepts.
  3. A Shopify Partner account to create and manage apps.
  4. Laravel installed on your local development environment.

Setting Up Your Development Environment

  1. Install Laravel: Begin by installing Laravel using Composer. Run the following command in your terminal:

    bash
    composer global require laravel/installer

    Create a new Laravel project:

    bash
    laravel new shopify-app

  2. Set Up Shopify App Credentials: Log in to your Shopify Partner account and create a new app. Obtain the API key and secret key which will be used for authenticating API requests.

  3. Install Necessary Packages: To interact with Shopify’s API, you’ll need to install a package like ohmybrew/Basic-Shopify-API:

    bash
    composer require ohmybrew/basic-shopify-api

  4. Configure Environment Variables: Add your Shopify credentials to the .env file in your Laravel project:

    env
    SHOPIFY_API_KEY=your_api_key
SHOPIFY_API_SECRET=your_secret_key
SHOPIFY_APP_SCOPES=read_products,write_orders
SHOPIFY_APP_REDIRECT_URI=https://yourapp.com/auth/callback

Creating a Shopify App

  1. Set Up Routes and Controllers: Create routes for authentication and callbacks in routes/web.php:

    php
    Route::get('/auth', 'ShopifyController@auth');
Route::get('/auth/callback', 'ShopifyController@callback');

    Create a controller using Artisan:

    bash
    php artisan make:controller ShopifyController

  2. Implement Authentication Logic: In ShopifyController, add methods to handle authentication and the callback:

    php
    use Illuminate\Http\Request;
use OhMyBrew\BasicShopifyAPI;

class ShopifyController extends Controller
{
    public function auth()
    {
        $api = new BasicShopifyAPI();
        $api->setApiKey(env('SHOPIFY_API_KEY'));
        $api->setApiSecret(env('SHOPIFY_API_SECRET'));
        $scopes = env('SHOPIFY_APP_SCOPES');
        $redirectUri = env('SHOPIFY_APP_REDIRECT_URI');
        $url = $api->getAuthUrl($scopes, $redirectUri);
        return redirect($url);
    }

    public function callback(Request $request)
    {
        $api = new BasicShopifyAPI();
        $api->setApiKey(env('SHOPIFY_API_KEY'));
        $api->setApiSecret(env('SHOPIFY_API_SECRET'));
        $code = $request->get('code');
        $token = $api->requestAccessToken($code);
        session(['shopify_token' => $token]);
        return redirect('/home');
    }
}

  3. Handle Shopify API Requests: With authentication set up, you can now make API requests. For example, to fetch products:

    php
    public function fetchProducts()
{
    $api = new BasicShopifyAPI();
    $api->setAccessToken(session('shopify_token'));
    $response = $api->get('/admin/api/2024-01/products.json');
    $products = $response->body->products;
    return view('products.index', ['products' => $products]);
}

Developing Your Shopify App

  1. Create Views: Set up views in resources/views to display data from Shopify. For example, resources/views/products/index.blade.php:

    blade
    


    Products


    
    Products
    
    
      
        @foreach ($products as $product)
            
    • {{ $product->title }}
      • 
        @endforeach
    
    



  2. Add Additional Features: Based on your app’s requirements, you might add more features such as order management, customer interactions, or inventory tracking. Utilize Shopify's API documentation to explore available endpoints and functionalities.
    3. Testing Your Shopify App
    1. Use Shopify’s Development Store: Test your app in a Shopify development store to ensure it functions correctly. Install the app from your Partner dashboard and verify that it integrates with Shopify as expected.
    2. Debugging: Use Laravel’s built-in debugging tools and log messages to troubleshoot any issues. Check the Shopify API response for errors and adjust your code accordingly.
    Deploying Your Shopify App
    1. Prepare for Deployment: Ensure your app is production-ready by testing all features thoroughly and handling any edge cases. Configure environment variables and deploy your app to a live server.
    2. Submit Your App: Once your app is ready, submit it for review in the Shopify Partner dashboard. Follow Shopify’s app submission guidelines to ensure a smooth approval process.
    Conclusion
Developing a Shopify app using Laravel can greatly enhance your e-commerce capabilities and provide valuable solutions to merchants. By following this tutorial, you’ve learned how to set up your development environment, create authentication flows, interact with Shopify’s API, and deploy your app. As you continue to develop your app, keep in mind the importance of testing and adhering to best practices for a seamless user experience.
