`GiftCardCashOutTransaction` is now resolvable from `GiftCardTransaction`

Starting with GraphQL Admin API version 2026-07, the [GiftCardCashOutTransaction](https://shopify.dev/docs/api/admin-graphql/2026-07/objects/GiftCardCashOutTransaction type is introduced as a new variant of the GiftCardTransaction interface. This type specifically represents transactions where a gift card balance is paid out through a point of sale (POS) system.

In previous API versions, such as 2026-04 and earlier, these transactions were classified as GiftCardDebitTransaction. From version 2026-07 onwards, they are identified as GiftCardCashOutTransaction. To accurately differentiate cash-out transactions from credit and debit transactions, use the __typename field when querying giftCard.transactions.

Below is an example query:

giftCard(id: "...") {
  transactions(first: 10) {
    nodes {
      __typename
      ... on GiftCardCashOutTransaction {
        id
        amount { amount currencyCode }
      }
    }
  }
}
