Laravel Shopify API Wrapper

Build Status Latest Stable Version

This Package provides a easy way for you to building Shopify Apps with Laravel 5. The OAuth authentication is extended upon Laravel's Socialite.

This package supports both public and private apps, including billing.

Installation

You can install this package via composer with:

composer require bnmetrics/laravel-shopify-api

Or add to your Laravel project composer.json file:

"require": {

    "bnmetrics/laravel-shopify-api" : "~1.0",
}

To publish the shopify.php configuration file to app/config run:

php artisan vendor:publish --provider='BNMetrics\Shopify\ShopifyServiceProvider'

Configuration

Set shopify environment variables your .env file:

SHOPIFY_KEY=YOUR_API_KEY_HERE
SHOPIFY_SECRET=YOUR_API_SECRET_HERE
SHOPIFY_REDIRECT=https://app.example.com/oauth/authorize

Register the service provider in your app/config/app.php:

"providers" => [
   // other providers...
   BNMetrics\Shopify\ShopifyServiceProvider::class,
]

Also add the Shopify facade in your aliases array in app/config/app.php:

"aliases" => [
   // other facades...
   'Shopify' => BNMetrics\Shopify\Facade\ShopifyFacade::class,
] 

Basic Usage

Now, you are ready to make a shopify app! here is an example of how it might be used in a controller to retrieve information from a shop via GET request to the API endpoint:

<?php

namespace App\Http\Controllers;

use Shopify;

Class myShopify extends Controller
{
  protected $shop = "example.myshopify.com";
  protected $foo;
  protected $scopes = ['read_products','read_themes'];
  
  public function getPermission()
  {
    $this->foo = Shopify::make($this->shop, $this->scopes);
    return $this->foo->redirect();
  }
  
  public function getResponse(Request $request)
  {
    $this->getPermission();
    
    // Get user data, you can store it in the data base
    $user = $this->foo->auth()->getUser();
    
    //GET request to products.json
    return $this->foo->auth()->get('products', ['fields'=>'id,images,title']);
  }
}

Alternatively, if you already have a token to a specific shopify domain. You can retrieve the API response by using the retrieve() method like so:

$this->foo = Shopify::retrieve($this->shop, $access_token);

//Get the user information
$user = $this->foo->getUser();

Next you will need to make two routes:

Route::get('/oauth/authorize', 'myshopify@getResponse');
Route::get('/shopify', 'myShopify@getPermission');

CRUD requests to the API endpoints

As of version 1.0.3, GET, PUT, POST, DELETE requests are supported for this package. To make requests, simply call the respective methods following the URL structure of of each endpoints, adding suffix such as "All", "Count", "ById".

API endpoints are referred to as "tiers", for example,

  • products endpoints('admin/products.json', 'admin/products/{id}.json') are tier 1;

  • productsImages endpoints('admin/products/{product_id}/images.json', 'admin/products/{product_id}/images/{image_id}.json') are tier 2;

  • Currently, only ordersFulfillmentsEvents have tier 3 ('admin/orders/{order_id}/fulfilments/{fulfillment_id}/events.json', 'admin/orders/{order_id}/fulfilments/{fulfillment_id}/events/{event_id}.json');

Below is an example of how to make requests to endpoints:

//assuming $shop is already oAuth verified Shopify.php object

//GET request
$shop->getProductsAll();
$shop->getProductsById(2324564);


//POST Request
//Options to be passed as request body are manditory for some API endpoints
$options = [
'product' => [
    'title' => 'my cool products',
    'body_html' => '<p> my cool product! </p>',
    'vendor' => 'My Shopify Shop',
    'images' => [
         'src' => 'https://example.com/my_product.jpg'
    ],
  ]
];
$shop->createProducts($options);

//PUT (upload/update an image source)
$modifyOptions = [
   'asset' => [
       'key' => 'assets/example.jpg',
       'src' => 'https://www.example.com/example.jpg'
   
   ]
];
$shop->modifyThemesAssets($modifyOptions);



//DELETE
$productID = 121421;
$imageID = 323546;
$shop->deleteProductsImages($productID, $imageID);

Config file

More endpoints can also be added to shopify.php config file $endpoints array following the same pattern.

  • First Tier names should be the array key of the first dimension, and the array values are tier 2;
  • if the endpoint has a tier 3 endpoint, add a key 'tier 3';
  • if the tier 2 endpoint node does not need a tier 1 ID to be accessed, the endpoint can be indicated in the 'tierTwoWithoutId' array.

Billing

As of version 1.0.2, billing support has been added to this package. It supports all three of the billing options shopify provides: RecurringCharge, ApplicationCharge and UsageCharge.

If you are to use Billing for your Shopify app, Add the following onto your config/app.php file:

Register the service provider in your app/config/app.php:

"providers" => [
   // other providers...
   BNMetrics\Shopify\BillingServiceProvider::class,
]

Also add the ShopifyBilling facade in your aliases array in app/config/app.php:

"aliases" => [
   // other facades...
   'ShopifyBilling' => BNMetrics\Shopify\Facade\BillingFacade::class,
] 

Billing Usage

As all shopify charges will need to be activated after creation, we will add a route called activate:

Route::get('activate', 'myShopify@activate');

For our previous example controller, you can change the getResponse method like so:

  public function getResponse(Request $request)
  {
    $this->getPermission();
    
    // Get user data, you can store it in the data base
    $user = $this->foo->auth()->getUser();
    
    $return_url = url('activate');
    $options = ['name'=>'my awesome App', 'price' => '10',
                'return_url' => $return_url,
                ];
    
    // Redirect the user to the myshopify page to approve the charge
    //Saving user into the session for the activate method
    return \ShopifyBilling::driver('RecurringBilling')
                            ->create($this->user, $options)->redirect()->with('user', $this->user);      
  }

create() method accepts an validated Shopify object or a User Object, and the options for the charge. Refer to the Property section for different options you can pass in:

RecurringBilling, ApplicationCharge, UsageCharge,

Then we would need to add the activate method():

public function activated(Request $request)
{
    $user = $request->session()->get('user');
    $activated = \ShopifyBilling::driver('RecurringBilling')
            ->activate($user->name, $user->token, $request->get('charge_id'));
    
    return redirect('/myapp-homepage');
}

activate method handles all "status", not only 'accepted', but also when user declines the charge;

Usage Charge

For usage charges, as it is based uppon an existing recurring charge, an activated recurring charge instance must be passed before creating a usage charge.

The recurring charge also require to have 'capped_amount' and 'terms'.

We can modify our activate() method in our controller like so:

public function activated(Request $request)
{
    $user = $request->session()->get('user');
    $activated = \ShopifyBilling::driver('RecurringBilling')
            ->activate($user->name, $user->token, $request->get('charge_id'));
    
    $usageOption = [ 'price' => '10', 'description' => 'my awesome app description'];
    
    \ShopifyBilling::driver('UsageCharge')->setBase($activated)->create($user, $usageOption);
    
    return redirect('/myapp-homepage');

}
