The /mergeBalance endpoint of our Stored Value API lets you transfer the full value of a gift card or other type of stored-value card to another one. The source and target card need to be from the same gift card provider.

When you transfer the value from one gift card or stored-value card to another, the way to specify the card details of the target card depends on whether you tokenized a payment that the shopper made with this card.
