# Discount​Effect

union

Requires Apps must have `read_discounts` access scope.

The type of discount that will be applied. Currently, only a percentage discount is supported.

## Possible types

* [Discount​Amount](https://shopify.dev/docs/api/admin-graphql/latest/objects/DiscountAmount)

  OBJECT

  The fixed amount value of a discount, and whether the amount is applied to each entitled item or spread evenly across the entitled items.

  * amount

    [Money​V2!](https://shopify.dev/docs/api/admin-graphql/latest/objects/MoneyV2)

    non-null

    The value of the discount.

  * applies​On​Each​Item

    [Boolean!](https://shopify.dev/docs/api/admin-graphql/latest/scalars/Boolean)

    non-null

    If true, then the discount is applied to each of the entitled items. If false, then the amount is split across all of the entitled items.

* [Discount​Percentage](https://shopify.dev/docs/api/admin-graphql/latest/objects/DiscountPercentage)

  OBJECT

  Creates percentage-based discounts that reduce item prices by a specified percentage amount. This gives merchants a flexible way to offer proportional savings that automatically scale with order value.

  For example, a "20% off all winter clothing" promotion would use this object to apply consistent percentage savings across different price points.

## Fields with this union

* [Discount​On​Quantity.effect](https://shopify.dev/docs/api/admin-graphql/latest/objects/DiscountOnQuantity#field-DiscountOnQuantity.fields.effect)

  OBJECT

  Defines quantity-based discount rules that specify how many items are eligible for a discount effect. This object enables bulk purchase incentives and tiered pricing strategies.

  For example, a "Buy 4 candles, get 2 candles 50% off (mix and match)" promotion would specify a quantity threshold of 2 items that will receive a percentage discount effect, encouraging customers to purchase more items to unlock savings.

  The configuration combines quantity requirements with discount effects, allowing merchants to create sophisticated pricing rules that reward larger purchases and increase average order values.
