Shopify API – Create A Price Rule Using Postman In Shopify

In Shopify, if you want to use Postman to create a Discount, firstly you need to create a Price rule. The price rule will allow you to know what value of the discount, when and how you can apply it to customers.

Price rules have 2 ingredients: Entitlements and prerequisites. You can understand as follows:

  • Entitlements are the precise resources to which a discount applies, such as goods, variations, or collections. 
  • Prerequisites are the conditions that must be satisfied in order for the discount to apply to the resources that are eligible.

Example: Free Shipping for all customers buying over $50.

Now, I will show you how to create a price rule that gives the buyer $10 for an order. 

Step 1: Generate API credentials from the Shopify admin

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
Generate API credentials from the Shopify admin
  • 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 Price Rule Using Postman In Shopify

  • 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
Code language: JavaScript (javascript)
  1. {username} – The API key that you generated.

  3. {shop} – The name of your development store.
