Card Transaction Type Enum

This enumeration identifies the nature of a transaction occurring on a card. These values help differentiate between standard purchases, reversals, and internal account adjustments.

Enum Value	Description
`transfer_in`	Card account transfer in card.
`transfer_out`	Card transfer out to card account.
`consumption`	A transaction was made on the credit card.
`refund`	After the credit card transaction, this order was refunded, or a refund occurred for a previous transaction, which was credited back to the current credit card.
`settlement_debit`	For example, if $10 was pre-paid for a ride on Uber, but the final settlement deducted $15, the platform will generate an order with a difference of $5.
`settlement_refund`	For example, if $10 was pre-paid for a ride on Uber, but the final settlement deducted $8, the platform will generate an order with a difference of $2.
`reversal`	The logic is consistent with a refund, but this type of order often occurs before the order settlement.
`declined_refund`	In some cases, if our platform successfully authorizes a transaction, a charge will be generated. However, if the order fails due to issues with the bank or other processing errors, we will create a new order to refund the charge.
`auth_fee`	Authorization Fee.
