As of GraphQL API version `2026-04`, Shopify Functions can now access detailed discount information at three levels:

1. **Cart-level**: All discount applications on the cart.
2. **Line item-level**: Discounts allocated to specific line items.
3. **Delivery-level**: Discounts allocated to delivery groups.

Based on the [function execution order](https://shopify.dev/docs/api/functions/2026-04#function-execution-order-in-checkout), only functions that execute after discounts can see complete discount information.
