How to set price rules by a product variant id for a specific quantity (Shopify GraphQl API)

We’re now in the second week of the #4WeeksOfShopifyDev challenge.

In the sixth article, As requested, I’ll be talking about how to set price rules by a product variant id for a specific quantity using the Shopify GraphQl API

We’ll build a discount (80% OFF) that will be applied automatically when the user has a specific product variant with a minimum quantity of 2 items
Let do it!

I’ll be using the Shopify Admin API explorer app

• You need to install the Shopify Admin API app
• Paste this code in GraphQl query

mutation discountAutomaticBasicCreate($automaticBasicDiscount: DiscountAutomaticBasicInput!) {  discountAutomaticBasicCreate(automaticBasicDiscount: $automaticBasicDiscount) {    automaticDiscountNode {      id    }    userErrors {      code      extraInfo      field      message    }  }}

In this code, we have this mutation function to creates a basic automatic discount and it’s will return the id of the generated discount

• Paste this JSON object in the query variables section

{  "automaticBasicDiscount": {    "title": "Ilias Challenge",    "startsAt": "2020-12-07T11:26:29.519Z",    "minimumRequirement": {      "quantity": {        "greaterThanOrEqualToQuantity": "2"      }    },    "customerGets": {      "value": {        "percentage": 0.8      },      "items": {        "products": {          "productVariantsToAdd": "gid://shopify/ProductVariant/YOUR-PRODUCT-VARIANT-ID"        }      }    }  }}

Notes:

Percentage accepts a value between 0.00–1.00 80% — 0.80

Your Product Variant ID: you can get it when editing a product variant, you’ll have in the URL

In this example:

https://ilias-demo.myshopify.com/admin/products/4805542674516/variants/32963135799380

Variant_ID= 32963135799380
