1.10. Deposit To Card Transfer

Introduction

Deposit to card transfer (D2C) is a money transfer from Connecting Party bank account (Deposit) to Receiver bank card number (PAN) or tokenized card data (Card Reference ID). Deposit to card transfer is made in three steps:

Initial payment – any transaction type with present cardholder data will work as initial payment - sale, preauth, transfer, etc. It is important to make the initial payment the most secure way in order to guarantee that a real card holder is registering the card.
Card registration – get card-ref-id (Card Reference ID) and register Customer’s card in their profile. Card Reference ID can be used unlimited number of times, while the bank card is active.
Money transfer – run v4/transfer-by-ref/ API command using destination-card-ref-id obtained on previous step.
See terms definitions in Glossary.
