Dispute Service

Overview

The Dispute Service helps you manage chargeback disputes across payment processors using the PHP SDK. When customers dispute transactions with their banks, this service enables you to track dispute status, submit evidence, and make informed decisions.

Business Use Cases:

• E-commerce fraud defense - Submit delivery proof and receipts to contest illegitimate chargebacks

• Service businesses - Provide service documentation and customer communication records

• Subscription disputes - Submit recurring transaction agreements and cancellation policies

• Revenue recovery - Defend valid transactions to minimize chargeback losses
