Shopify API 2026 – Create, Update, and Delete A Discount Code With Postman In Shopify

In a previous article, I showed you how to create a Price Rule with Postman, Price rule is a necessary condition to create a discount code. You can define the parameters for a discount with the Price Rule resource, but you’ll need to create associated discount codes for customers. I will show you how to create, update and delete a discount code with Postman In Shopify. 

Create A Discount Code Using Postman In Shopify

Step 1: Generate API credentials from the Shopify admin

 

• • Click Create a new private app

• • In the App details section, enter a name for your app, and an emergency developer email

• • In the Admin API section, select the areas of your store that you want the app to access

 

• • Click Save

The Admin API section displays the app’s API key and password when you save the app’s details. 

Step 2: Create a discount code using Postman in Shopify

Before creating a discount code using Postman, you must create a Price Rule. Remember that Price Rule ID is to use in this step. 

 

• • Log in to your Postman and create a new workspace

• • Create a new POST with this URL:

https://{username}:{password}@{shop}.myshopify.com/admin/api/{api-version}/{resource}.json

• {username} – The API key that you generated.
• {password} – The API password that you generated.
• {shop} – The name of your development store.
• {api-version} – The supported API version that you want to use.
• {resource} – A resource endpoint from the REST Admin AP

Or you can copy this example in the Shopify Admin, remember to change {resource} to {price_rules/price rule ID/discount_codes}:

<a href="https://33a72f01e02987636e1c1a9a4e95c840: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@hexasync.myshopify.com/admin/api/2021-10/price_rules/1001616998463/discount_codes.json">https://33a72f01e02987636e1c1a9a4e95c840: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@hexasync.myshopify.com/admin/api/2021-10/price_rules/1001616998463/discount_codes.json</a>
