A simple Shopify API client in PHP.

The canoncial repository for this stream of development is

This API Client is still in a pre-1.0 state, so you can expect:

  • some bugs (feel free to submit a pull request with bug fixes and test coverage)
  • possibly some breaking API changes between v0.10 and v1.0


  • PHP 5.3 (or higher)
  • ext-curl, ext-json

Development Requirements

  • phpunit/phpunit 3.7

Getting Started

Install shopify-php via Composer

Create a composer.json file if you don't already have one in your projects root directory and require shopify-php:

  "require": {
    "offshoot/shopify-php": "0.10.x"

To learn more about Composer, including the complete installation process, visit

Using cURL

If you're using a cURL based HttpClient like the CurlHttpClient, you will want to include the cacert.pem file that can be found at

You can add this as a dependency in your composer file. Your composer.json might look something like this:

  "require": {
    "offshoot/shopify-php": "0.10.x",
    "haxx-se/curl": "1.0.0"
  "repositories": [
      "type": "package",
      "package": {
        "name": "haxx-se/curl",
        "version": "1.0.0",
        "dist": {
          "url": "",
          "type": "file"

You will be able to find the cacert.pem file in vendor/haxx-se/curl/cacert.pem



If you do not already have a Shopify API Permanent Access Token, you will need you authenticate with the Shopify API first

$pathToCertificateFile = "vendor/haxx-se/curl/cacert.pem";
$httpClient = new \Shopify\HttpClient\CurlHttpClient($pathToCertificateFile);

$redirector = new \Shopify\Redirector\HeaderRedirector();

$authenticate = new \Shopify\Api\AuthenticationGateway(
    $httpClient, $redirector

    ->usingClientId('XXX1234567890') // get this from your Shopify Account
    ->withScope(array('write_products', 'read_orders'))

This will redirect your user to a Shopify login screen where they will need to authenticate with their Shopify credentials. After doing that, Shopify will perform a GET request to your redirect URI, that will look like:


Your application will need to capture the code query param from the request and use that to get the permanent access token from Shopify

$client = new Shopify\Api\Client($httpClient);

// validate the Shopify Request
if ($client->isValidRequest($_GET)) {

    // exchange the token
    $permanentAccessToken = $authenticate->forShopName('mycoolshop')

TODO: build request validation into exchange process TODO: have AuthenticationGateway extend Api\Client

Interacting with the Shopify API

Once you have a valid Shopify Permanent Access Token, you can start making calls to the Shopify API

First setup an instance of the Shopify API client.

$client = new \Shopify\Api\Client($httpClient);

Then you're ready to start interacting with the Shopify API. Maybe you want to get all of the products from your store

$products = $client->get('/admin/products.json', array(
    'collection_id' => '987654321'

Maybe you want to get the details of a specific order

$order = $client->get('/admin/orders/123456789.json');

Or maybe you want to create a new Order

$order = $client->post('/admin/orders.json', array(
    'order' => array(
        'line_items' => array(
            0 => array(
                'grams' => 1300,
                'price' => 74.99,
                'quantity' => 3,
                'title' => "Big Brown Bear Boots",
        'tax_lines' => array(
            0 => array(
                'price' => 29.25,
                'rate' => 0.13,
                'title' => "HST",
        'transactions' => array(
            0 => array(
                'amount' => 254.22,
                'kind' => "sale",
                'status' => "success",
        'total_tax' => 29.25,
        'currency' => "CAD",
