Initiates the straight-through processing (STP) of an inbound transaction of digital assets to the cardId specified in this endpoint, converted automatically to the base currency of the card. It specifies the card to which funds should be allocated, which is relevant in the case of a cardholder with more than one card.
The request asserts that the transaction has already been completed on-chain, and (if it can be verified electronically) the deposit amount appears immediately in the card's ledgerBalance.
The end-to-end process is automated and operatively instant but delays may be encountered on-chain, in the exchange, or in correspondent banking, and funds won't reflect in the availableBalance until the clearing process has completed.
If the transaction can't be verified after 24 hours, it will expire and would need to be re-initiated using this endpoint if it remained applicable.
