Card2Card (p2p)

Currently, it is possible to make transfers from card to card (card2card) using the payer’s linked card without his direct participation.

For these purposes, it is necessary to first carry out tokenization of card data for the debit card

In this case, both the card token obtained as a result of one of the tokenization options and the full card number can be used as the recipient’s card.

Within this API call, an object is added to the standard callsource, where as the valuecardtransmittedidpreviously completed successful tokenization of full card data or [card number](./api_tokenization.md#tokenization-card number) and objectdestination, where as the valueknownCardNumberthe card number is sent or as an objectcardtransmittedidpreviously successful tokenization of full card data or [card number](./api_tokenization.md#tokenization-card number), as well as the value"interactive": false, responsible for ensuring that the operation takes place without 3d-secure.

IMPORTANT! In case of transfer"interactive": truethe request will fail with an error

The transaction is carried out asynchronously. As a result of the request, you will synchronously receive idpayments, and then callback-notification will arrive asynchronously.

Parameter	Required		Parameter	Required
payment	Yes		destination	Yes
payment.action	Yes		destination.card/knownCardNumber	Yes
payment.orderId	Yes		interactive	Yes
payment.price	Yes
source	Yes
source.card	Yes

Synchronous response and asynchronous callback-notification can contain a wider set of parameters compared to the example.
