# Discounts

The API for interacting with discounts.

## OrderStatusApi

* **discountAllocations**

  **SubscribableSignalLike\<CartDiscountAllocation\[]>**

* **discountCodes**

  **SubscribableSignalLike\<CartDiscountCode\[]>**

  **required**

  A list of discount codes applied to the purchase.

### SubscribableSignalLike

Represents a read-only value managed on the main thread that an extension can subscribe to. Example: Checkout uses this to manage the state of an object and communicate state changes to extensions running in a sandboxed web worker. This interface is compatible with \[Preact's ReadonlySignal]\(https://github.com/preactjs/signals/blob/a023a132a81bd4ba4a0bebb8cbbeffbd8c8bbafc/packages/core/src/index.ts#L700-L709). Some fields are deprecated but still supported for backwards compatibility. In version 2025-10, \[\`StatefulRemoteSubscribable\`]\(https://github.com/Shopify/remote-dom/blob/03929aa8418a89d41d294005f219837582718df8/packages/async-subscription/src/types.ts#L17) was replaced with \`ReadonlySignalLike\`. Checkout will remove the old fields some time in the future.

* current

  ```ts
  T
  ```

* destroy

  ```ts
  () => Promise<void>
  ```

* subscribe

  Subscribes to value changes and calls the provided function whenever the value updates. Returns an unsubscribe function to clean up the subscription. Use to automatically react to changes in the signal's value.

  ```ts
  (fn: (value: T) => void) => () => void
  ```

* value

  The current value of the signal. This property provides immediate access to the current value without requiring subscription setup. Use for one-time value checks or initial setup.

  ```ts
  T
  ```

### CartDiscountCode

* code

  The code for the discount

  ```ts
  string
  ```
