PHP SDK for Shopify API

, _(*1)

Shopify PHP SDK

This SDK was created to enable rapid efficient development using Shopify's API., _(*2)

Installation

Easily install this package with composer, _(*3)

composer require robwittman/shopify-php-sdk

Before you can start using this SDK, you have to create a Shopify Application You can now use the API key and secret to generate access tokens, which can then access a stores data, _(*4)

Initialization

To initialize the Api Client:, _(*5)

$client = new Shopify\Api(array(
    'api_key' => '<api_key>',
    'api_secret' => '<api_secret>',
    'myshopify_domain' => 'store.myshopify.com',
    'access_token' => '<store_access_token>'
));

If you are using a Private App for use on an individual store:, _(*6)

$client = new Shopify\PrivateApi(array(
    'api_key' => '<api-key>',
    'password' => '<password>',
    'shared_secret' => '<shared-secret>',
    'myshopify_domain' => '<store>.myshopify.com'
));

Once the client is initialized, you can then create a service, and use it to communicate with the api, _(*7)

Reading

$service = new Shopify\Service\ProductService($client);
$service->all(); #Fetch all products, with optional params
$service->get($productId); # Get a single product
$service->count(); # Count the resources

Creating

$service = new Shopify\Service\ProductService($client);
$product = new Shopify\Object\Product();
# Set some product fields
$product->title = 'Test Product';
$product->vendor = 'Printer';

$service->create($product);

Updating

$service = new Shopify\Service\ProductService($client);
$product = $service->get($productId);
# Set some product fields
$product->title = 'Test Product';
$product->vendor = 'Printer';

$service->update($product);

Deleting

$service = new Shopify\Service\ProductService($client);
$service->delete($productId);

GraphQL

Query

$service = new Shopify\Service\GraphQLService($client);
$service->graph(
  '{
    products(query: "created_at:<2019", first: 5) {
      edges {
        node {
          title
          description
        }
      }
    }
  }'
);

Mutation

$service = new Shopify\Service\GraphQLService($client);
$service->graph(
  'mutation productCreate($input: ProductInput!){
    productCreate(input: $input) {
      product {
        id
      }
    }
  }',
  ['input' => ['title' => 'Sweet new product','productType' => 'Snowboard','vendor' => 'JadedPixel']]
);

Authentication

Authentication to Shopify's API is done through access tokens, which are obtained through OAuth. To get a token, there is a helper library packaged with this client, _(*8)

$client = new Shopify\Api($params);
$helper = $client->getOAuthHelper();

$redirectUri = 'https://localhost/install.php';
$scopes = 'write_products,read_orders,...';

$authorizationUrl = $helper->getAuthorizationUrl($redirectUri, $scopes);
header("Location: {$authorizationUrl}");

At your redirect_uri, instantiate the helper again to get an access token, _(*9)

$client = new Shopify\Api($params);
$helper = $client->getOAuthHelper();

$token = $helper->getAccessToken($code);
echo $token->access_token;
echo $token->scopes;

By default, this uses simple session storage. You can implement a custom class that implements PersistentStorageInterface, pass that to new Shopify\Api(), and OAuthHelper will use that instead. This will be required if authorization requests and redirects may be directed to different servers., _(*10)

Using objects

Object properties can be accessed using object->property. Nested objects are instantiated classes. All timestamp fields are instances of \DateTime., _(*11)

use Shopify\Enum\Fields\ProductFields;
use Shopify\Enum\Fields\ProductVariantFields;

$product = $service->get($productId);
echo $product->created_at->format('Y-m-d H:i:s');
echo $product->title;

foreach ($product->variants as $variant) {
    echo $variant->option1;
    echo $variant->option2;
}
