* ### Update the variants and percentage value of a discount code

  #### Description

  Update an \[amount off discount]\(https://help.shopify.com/manual/discounts/discount-types/percentage-fixed-amount) that's applied on a cart and at checkout when customers enter a code. This example shows how to modify the discount to apply only to specific products, take 10% off the selected products, make it available for the first 100 orders, limit it to one use for each customer, and set an end date.

  #### Query

  ```graphql
