What is a dispute? How do I handle them?
A dispute (also known as a chargeback) occurs when a cardholder questions a charge with their bank or credit card company. When a dispute comes in, Stripe gets information about it from the bank, and displays one of eight reason categories to our users.
Depending on the reason, the Stripe Dashboard will guide the user through submitting the best type of evidence to support the charge, as outlined here: https://stripe.com/docs/disputes/categories. Once the user submits the dispute evidence to Stripe, Stripe will submit the evidence to the banks/card networks on their behalf, so that the user does not have to deal with these institutions directly.
To be notified about disputes, select email notifications through your Dashboard:https://dashboard.stripe.com/account/emails. (Select “Email me for: Disputes.”)
