International Credit Card (Legacy navigation V20260628)

Before reading this API documentation, be sure to review the API Description Guide

For credit card transactions, consumers maintain the right to initiate a dispute within 180 days of the charge date. When a dispute is filed, a dispute fee of $20 will be assessed per transaction.
Upon receiving a dispute notification, you have two options for response
- First: you may accept the dispute by submitting a response to the issuing bank affirming that you do not contest the refunded amount.
- Second, you may counter the dispute by completing a guided submission process that prompts you to provide relevant evidence and supporting documentation for your case.
Should you elect to counter a dispute, an additional dispute countered fee of $20 will be applied. In the event that the issuing bank does not accept your counter materials and rules in favor of the consumer, both the dispute countered fee will be deducted and the consumer’s payment will be refunded to them.
Regarding fee refunds, Haipay will return the dispute countered fee if you successfully win the dispute. However, unless explicitly stated otherwise in your Haipay contract, the initial dispute fee is non-refundable under all circumstances.
