Dispute transactions processing

CHARGEBACK, SECOND_PRESENTMENT, SECOND_CHARGEBACK transactions are
used to dispute already settled payment. CHARGEBACK, SECOND_CHARGEBACK are initiated by issuer and SECOND_PRESENTMENT is initiated by acquirer.

ARBITRATION is the last step of dispute cycle when decision is made by international payment system and result of Arbitration may be either ARBITRATION_WON or ARBITRATION_LOST.

REVERSAL transactions are used to reverse back previously made CHARGEBACK, SECOND_PRESENTMENT, SECOND_CHARGEBACK or ARBITRATION transactions.

When processing these transactions, Payment Platform sends notification to Client’s Callback URL.
