New relatedTransaction value for gift cards API redeem transactions

The gift cards integration API includes a new relatedTransaction value in the TransactionInformationRedeem object for gift card redeem transactions. The relatedTransaction value is the Toast platform unique identifier for a previous gift card transaction. Your integration can use this identifier to confirm information about a previous, related transaction such as PIN verification. For example, if a restaurant employee adds a tip or gratuity to a transaction, the Toast POS reverses the initial redemption and sends another redemption with the new amount. This value provides the identifier of the initial transaction. If the current transaction is not part of an adjustment (for example, reversing a transaction) the relatedTransaction value is null.
