REST Admin API

REST Admin API lets you build apps and other integrations for the Shopify admin using REST. With the API, you can create apps that offer functionality at every stage of a store's operation, including shipping, fulfillment, and product management.

You can read our REST Admin API documentation and REST Admin API reference for more information.

Making your first REST request

REST Admin API endpoints are organized by resource . You'll need to use different API endpoints depending on the service that your app provides. There are two different ways of doing that with this library:

REST resources

REST resources are objects that represent the REST endpoints in the Admin API. This library provides classes for the endpoints in all supported versions of the API. We don't provide classes for the unstable version because it may change at any point, which would cause the resource classes to become outdated.

The resource classes will provide methods for all endpoints described in the REST reference docs. Please see the references for how to use a specific resource.

REST client

The REST client uses get, post, put, and delete requests to retrieve, create, update, and delete resources respectively.

Parameter Type Required? Default Value Notes
path string Yes The requested API endpoint path. This can be one of two formats:
  • The path starting after the /admin/api/{version}/ prefix, such as 'products', which executes /admin/api/{version}/products.json
  • The full path, such as /admin/oauth/access_scopes.json
body string or array No null Only post, and put methods can have body
headers array No [] Any extra headers to send along with the request
query array No [] Query parameters as an associative array
tries int No null How many times to attempt the request
dataType No No DATA_TYPE_JSON Only post, and put methods can have body

In the following example we will retrieve a list of products from a shop using Shopify\Clients\Rest class.

use Shopify\Clients\Rest;

$client = new Rest($session->getShop(), $session->getAccessToken());
$response = $client->get('products');

This request returns an instance of Shopify\Clients\RestResponse. The response object includes response statusCode, body, headers, and pagination information. To access the response attributes you can use getStatusCode, getBody and getHeaders respectively. There is also a convenience method getDecodedBody that will give you the JSON decoded associative array of the response body.

Pagination

REST endpoints support cursor-based pagination. When you send a request to a REST endpoint that supports cursor-based pagination, the response body returns the first page of results, and a response header returns links to the next page, and the previous page of results (if applicable). For more information check Make paginated requests to the REST Admin API tutorial.

Shopify\Clients\Rest helps you manage pagination by giving you the information you need. The response object of a get operation includes pagination information. To retrieve the pagination information call $result->getPageInfo().

You can serialize the pageInfo and save it between requests to be able to access the next or previous page if present.

$serializedPageInfo = serialize($result->getPageInfo());

To get the next page.

$pageInfo = unserialize($serializedPageInfo);
$result = $client->get('products', [], $pageInfo->getNextPageQuery());

PageInfo gives you some convenience methods to determine whether there is there are more pages.

method Return type Notes
hasNextPage() bool false if there is no more page
hasPreviousPage() bool false if there is no more page
getNextPageQuery() array Query to get the next page
getPreviousPageQuery() array Query to get the previous page
