How to Get Discount Codes already applied in Shopify Function input?

[Nico4]

The graphQL (Shopify Functions - Product API) does not seem to return the Discounts or Codes already applied in the Cart (ie. Automatic Discount)

Graphql:

query Input($tags: [String!]!) {
  cart {
    cost {
      subtotalAmount {
        amount
      }
      totalAmount {
        amount
      }
    }
    lines {
      quantity
      cost {
        amountPerQuantity {
          amount
        }
        compareAtAmountPerQuantity {
          amount
        }
        subtotalAmount {
          amount
        }
        totalAmount {
          amount
        }
      }
      merchandise {
        __typename
        ... on ProductVariant {
          id
          product {
            doTagsMatch: hasAnyTag(tags: $tags)
            id
          }
        }
      }
    }
  }
  discountNode {
    metafield(namespace: "$app:discount-price", key: "function-configuration") {
      value
    }
  }
}

Hi there 👋

Could you explain your use case why you need to access that discount information?

[Nico4]

The Merchant is asking us to replicate what we did with Shopify Scripts.

Logic:

Increase or Decrease the % of discount based on:

   - Entered Discount code

   - Product Tag

Example:

- User entered the Coupon Code EXTRA20 (20% discount)

- The Product has tag Sale (will get an extra 10% Off)

Result: We increase the Discount to 30%

Thanks for providing that additional context! 

I will provide this feedback to the team!
Keep your eyes out for new releases in this area, coming soon.

When can we expect the release of this feature?

Hi @lizk , 

I am facing similar problem. Here's my case:

Currently, our site has free shipping for purchases over $500

We'll give discount code to some customers - $300 off

Customer A purchases $700 worth of products. Checkout total price = $200 

i.e. shipping fees applies.

Customer B purchases $1000 worth of products. Checkout total price = $700

i.e. shipping fees does not apply.

We would like to let both customer A & B enjoy free shipping because both Customer A & B purchases over $500 worth of products before applying the discount code.
