A Brief Intro to the Shopify API

Published 27 February 2015 | Updated 24 October 2019 |


Shopify is one of the leading shopping platforms that is currently running more than 150k online stores with no less than $7 billion worth of sales. Sounds like a good customer bank for B2B vendors that help merchants organize and get more out of their online stores, and it is basically what it is.

Since applications and services can only access data from stores if connected to the platform they are based on, they integrate with shopping carts. The Shopify API helps them do so.

About the Shopify API

The API supports both XML and JSON, and works with such types of HTTP requests as GET, POST, PUT, and DELETE. An interesting issue worth consideration is methods supported by Shopify API. It works with 35 methods such as Category, Customer, Order, Product, etc. (you can find all of them in the API Reference section at the left bottom of the documentation). Each of the methods has purposes it can be used for and certain properties.

API authentication. Having obtained an API access token, you are ready to send authenticated requests to REST API. They come with this header, X-Shopify-Access-Token: {access_token} where you add the access token you have. But where do you get it?

As a developer you need to get credentials that would let you access particular data to start working on the project your Shopify client paid for. To get the API Key, you have to create a private app in the admin page of the Shopify store. Sounds too tangled? Let us clarify this by moving step-by-step.

  1. If you are not working for a client who would give you the necessary information or their email and password to login, there appears a necessity to register a shop on Shopify.

  2. Go to the admin page and press Apps>Private Apps>Create a Private App.

  3. There you find the API Key.

  4. Press the Tool button.

  5. Authentication.


To run a request, copy the example URL from the admin page and insert it into the address bar of your browser. Now press Enter and enjoy the order list returned to you.
