I. What is Shopify API

Shopify does provide an extensive API called the Shopify API, which allows developers to interact with various aspects of the Shopify platform.

The Shopify API enables developers to integrate Shopify with other systems, build custom storefronts, create apps, and perform a wide range of operations such as managing products, orders, customers, and inventory. It provides RESTful endpoints and supports various data formats like JSON and XML for communication.

While Shopify Hydrogen itself is a technology that focuses on creating customizable and performant storefronts using modern web technologies, the Shopify API can be used alongside Shopify Hydrogen to access and manipulate data from the Shopify platform.

It's important to note that Shopify frequently updates and enhances its platform and API offerings, so it's advisable to refer to the official Shopify documentation and developer resources for the most up-to-date information on the APIs available.

II. Key Features and Functionality of Shopify Hydrogen API

The key features and functionality of the Shopify Hydrogen API include:

These features and functionalities of the Shopify Hydrogen API provide developers with powerful tools to build and customize storefronts, integrate with third-party systems, and streamline e-commerce operations.

III. How does Shopify hydrogen storefront API work?

I believe it's crucial to give a brief explanation of how the Storefront API works before we dive right into the processes. First of all, only GraphQL can be used to access the Storefront API.

Storefront API can only be accessed using GraphQL.jpg

It's likely that you've utilized the REST protocol if you've ever worked with APIs. To access a specific collection of data via REST, you would only issue a GET request to a certain endpoint (URL). Or you could use a POST request if you wanted to alter data on the server side.

However, in GraphQL, every request you make to an API will be a POST request because, in GraphQL, you send a 'query' to a single endpoint, and that query, rather than that endpoint, defines what data you get back.

The idea of having a single endpoint and complete control over the data supplied in response to each request may initially seem complicated, but once you understand GraphQL, you'll see why it makes so much sense.

For illustration, suppose you only need to get the name of your store. Since the Shop object includes nine attributes if the Storefront API were a REST API, you would have to request the entire Shop object rather than just shop.name, which was the value you required.

I strongly advise you to visit the Storefront API's 'Getting Started' page and look at the examples. Here's a simple example:

{
    shop { 
    	name 
        primaryDomain { 
        	url 
            host 
        } 
    } 
}

Step 1: Create an access token

You must establish a private app inside your Shopify store and choose the checkbox to acquire a Storefront API access token in order to gain access to your store's data via the API.

The procedure seems as follows:

  • Select "Apps" from the admin sidebar.
  • 'Manage private apps' should be selected.
  • Select "Create a new private app" from the menu.
  • Include your app name (which can be as simple as "Storefront API") and email.
  • Select "Allow this app to access your storefront data using the Storefront API" by checking the appropriate box.
  • Click “Save”

When the app is finished being created, scroll down until the Storefront Access Token is listed in the final field. You only need this token to start utilizing the API.

Step 2: Make your first request

You can start sending API requests now that you have your Storefront API access token. We can be certain that we will want to access information like collections, goods, and variants as well as be able to generate a cart and submit it to Shopify as we are creating a bespoke Shopify storefront.

You may visit Shopify's official API docs to discover what information is offered, but let's start by creating a very simple query.

{
    shop {
    	name 
    }
}

As you can see, this query is really straightforward. All it does is access the name property of the shop object, which is located in the query root. The request's other settings, including the URL and headers, are more difficult in this instance.

The aforementioned query is loaded into the JS function apiCall() in the example below (which is taken from that tutorial).

Simply change [Your Shopify store address] and [Your storefront access token] to your store's URL and Storefront API key, navigate to any page inside your store, paste the code into your browser's JS console, and press Enter.

Congrats! Just now, you sent the Storefront API your first request.

Step 3: Create a unique storefront

It's time to start using the data you've learned to retrieve in the real world now that you've successfully made your first call to the API. Unfortunately, creating a completely functional online application is a vast subject that I will not directly address in this article. Instead, I will demonstrate how to start building without a framework or server using only vanilla HTML, CSS, and JS.

All you have to do to "run" the app is drag the index.html file into your browser.

shopify custom.png As you can see, it's really basic. Never mind, we're going to add a function to the app.js file that we'll use to render the first 20 items from our store into the page next, so don't worry. Our app.js file currently looks like this.

h-api2.png

Use queries to make a data request

In order to return a response from the Storefront API, what we're going to do is add a function right after the apiCall method that we'll use to combine the request settings with a particular query. The function appears as follows:

h-api3.png

Next, we'll call this function and use the data returned by the API response to display a list of items from our store along with an image and a description.

h-api4.png

The return value from the getProducts() function is a promise, which we then chain a.then() procedure to handle the server response.

To actually see the data that is returned by the store, include a console.log(response); statement somewhere within the.then() method. You can analyze and troubleshoot any issues by using the 'Network' and 'Console' tabs of your browser's devTools. If not, the aforementioned should have displayed the first 20 items from your store on the website.

Congrats! You now have:

  • Your request was verified by the access token.
  • Built a GraphQL query, submitted it to your store, and after that
  • Javascript was used to render the data to your page from the response of that API call.

Although the concept is quite simple, you should keep writing queries, putting them into functions, and rendering additional stuff to the website.

Using mutations, alter data in storage

When using the Storefront API, you'll typically just use queries to obtain data from your shop, but there are a few situations in which you might wish to perform a "mutation."

A mutation is similar to a query, but you use it to alter data rather than get it. The Storefront API is only minimally authenticated and has fewer options for modifying store data than the Admin API. Although you can essentially only change the checkout and customer objects, I still thought it was necessary to highlight them because it's a crucial component of any GraphQL API.

Here is an illustration of a mutation that you might want to use in your personal storefront application.

h-api5.png

As implied by the function's name, you can use this to log in a customer by sending the API an "input object" with the client's email and password (through customerAccessTokenCreate on line 3). The token (line 5) and any errors (line 9) will then be returned by the API.
