Giftcard get by code and update ballance

I have made a app which is sync with shopify giftcard to thirdparty giftcard but I am not able to find api for get Giftcard by code and also update balance.

Hi Mohammad,

Could you use the giftCards query which has a sortKey field, that has a value for CODE?

To change the balance, there’s mutations for giftCardCredit and giftCardDebit.
