Card Balance Control

Prepaid Card

The balance of a prepaid card is linked to the user's Infinity Account. To increase the prepaid card balance, funds from the Infinity Account can be transferred into the prepaid card via the Infinity Card transfer inAPI. To decrease the prepaid card balance, funds from the prepaid card can be transferred back into the Infinity Account via the Infinity Card transfer outAPI.

• Ensure that the card you are working with is a Prepaid Card.
• clientTransactionId is a custom identifier set by the user, and it will be returned in the callback.

Budget Card

A Budget Card does not hold a balance and cannot be used for fund transfers. It is managed through the Velocity Control API, which allows you to set spending limits according to daily, weekly, monthly, or yearly spending cycles.

Update Cardholder Information

The Update card API allows you to update the cardholder’s phone number and email address.

• This API only supports the BINs 414631 and 493728.

Card BIN Transaction Scenario Recommendations

Based on the provided card BIN, we recommend transaction scenarios with a higher likelihood of success.

• Different card BINs may have varying approval rates for supported transaction scenarios. Due to the platform's risk controls, there is no guarantee that a specific card will always be usable. Even within the same BIN, some cards may be successfully used in certain scenarios, while others may not.
