Mastering Shopify GraphQL with Postman

Imagine you’re trying to get data from your Shopify store to see how your sales are doing, but instead of using the usual dashboard, you want direct raw data to manipulate in your style. That's where knowing how to use GraphQL with Shopify through Postman comes into the picture!

Why Use Postman with Shopify's GraphQL?

First off, GraphQL is a powerful query language that lets you request exactly the data you want and nothing more. Shopify provides a GraphQL Admin API that allows deep customization and control, giving store data exactly as requested.

Postman, on the other hand, is a popular API client that makes it easier to experiment with API requests without writing lots of code. It's like having a remote control for your store’s API, simplifying the complexities of software backdoors!

Setting Up Everything

Alright, let's set up your tools. You're going to need:

• A Shopify store with admin access
• Postman installed on your computer

Step 1: Create a Shopify API Key

You can’t just walk up to Shopify’s data doors and demand information. You need a key!

1. Go to your Shopify admin area, and find the ‘Apps’ section.
2. Scroll down to manage private apps and create a new one.
3. Fill out the necessary details. Let’s name it 'GraphQL Postman Tester'—sounds techy enough!
4. Ensure the API key has permissions you need, usually read and write access works.

Save it, and you’ll get an API key and password. Think of these as your secret passcodes to your store’s data.

Step 2: Setting Up Postman

Open Postman:

1. Create a new request by clicking the ‘New’ button and selecting ‘Request’.
2. Name your request—something like ‘Shopify GraphQL Products Fetch’ to keep things clear.
3. Select ‘POST’ as the request type because GraphQL prefers talking this way—not the chatty type, you see.
4. Set the request URL to your Shopify GraphQL endpoint, usually something like https://{your-shopify-store-url}/admin/api/2021-07/graphql.json. Replace {your-shopify-store-url} with your actual store URL.

Step 3: Handling Authentication

Shopify loves secrecy! For this, in Postman:

1. Go to the ‘Authorization’ tab.
2. Type should be ‘Basic Auth’ .
3. Put the API key as your username and the password as...well, the password. This setup whispers to Shopify, “It’s me, let me in!”

Step 4: Writing Your First Query

It’s time to ask questions. And your first question might be listing all products:

{
  products(first: 5) {
    edges {
      node {
        title
        handle
        id
      }
    }
  }
}

This literally means, “Hey Shopify, show me the first 5 products, and oh, I only care about their title, handle, and ID.”

1. Paste this in the Body section of Postman, set it to ‘GraphQL’.
2. Hit send, and boom! You receive your data. Presto!

Moving Ahead: More Complex Queries

Let’s say you want to find out which items are low in stock. Modify your query:

{
  products(first: 5) {
    edges {
      node {
        title
        variants(first: 3) {
          edges {
            node {
              title
              inventoryQuantity
            }
          }
        }
      }
    }
  }
}

Here you’re diving deeper, not just looking at products but zooming into each variant and checking the inventory.

Pro Tips

• Stay Organized: As your experiments grow, use Postman’s Collections to keep requests organized like a well-maintained toolbox.
• Use Variables: Postman allows variables like {{store_url}} so switch across different stores quickly.
