Bank account details can be updated directly from the Stripe Dashboard:
Click on the Edit button next to the currently linked bank.
Provide the new bank account information.
Click Update bank account.
In some cases, you may be required to enter the previous bank account information as a security measure.
If your bank account information is updated while a payout is already in transit, that payout will be sent to your old bank account.
If you have any trouble updating your bank account information, such as having forgotten your previous bank account information, contact Stripe Support.
