Savvy merchants have access to an online portal called Connect Manager that can be used to manage all aspects of their prepaid programme, including the ability to set various policies that affect transaction processing such as:
Minimum Load Amount: Any attempt to top up (or refund) for less than this amount will result in the transaction amount being recalculated upwards to the minimum - response code 50
Maximum Load Amount: Any attempt to top up (or refund) for more than this amount will result in the transaction amount being recalculated downwards to the maximum - response code 51
Maximum Card Balance: Any attempt to top up (or refund) for an amount that would cause this to be exceeded is recalculated downwards so that the card balance is equal to the maximum balance - response code 52
Important: If you receive a response code 50, 51 or 52, the transaction has completed, but for an amount different to the amount originally requested. It is your responsibility to ensure your software handles this scenario correctly. Savvy are not responsible for implementations where response code 50/51/52 are not handled correctly
