Submit Evidence

Overview

The submit_evidence method uploads supporting documentation to contest a chargeback dispute. Evidence strengthens your defense by proving the transaction was legitimate and the customer received the product or service.

Business Use Case: A customer disputed a charge claiming they never received their order. You have delivery confirmation and the customer's signature. Submit this evidence to prove the order was delivered.

Purpose

Why submit evidence?

Evidence Type	Use Case

Customer communication	Email threads showing customer confirmed receipt
