A dispute (also known as a chargeback) occurs when a cardholder questions your payment with their card issuer. The dispute process and timeline varies by card network, but typically follows this process.
Every new dispute is assigned a reason code. If you believe the dispute's reason is incorrect or want to challenge the dispute, upload evidence supporting why the payment was valid through the Dashboard or via the API. Stripe sends submitted evidence to the card issuer for their review.
