A dispute occurs when an account owner contacts their bank to contest a payment to you for one of a number of possible reasons. What happens after that varies slightly across different card networks, but typically follows a standard pattern.
The process for disputes is outlined in our Stripe Docs page here:
If you believe that the dispute reason is incorrect and want to challenge it, you can upload evidence supporting why the payment was valid through the Dashboard or via the API. Once you have submitted your evidence, Stripe will send it to the card issuer for their review.
