Depending on the Transaction type parameter value, orders paid with Stripe get either “Paid” or “Authorized” order payment status. The “Paid” status is assigned to an order if the Transaction type setting is set to Authorization and Capture, and the “Authorized” status is assigned if the value is set to Authorize only, respectively.
Orders with the “Authorized” payment status require manual processing. The cart admin can either Capture or Void the order on the order details page, depending on the preferences.
Once an order gets the “Paid” status, you can refund it only.

To refund the order in full just click on the Refund button on the order details page and confirm the action.
For a partial refund, specify the amount you want to refund in the field opposite the Refund button and click Refund.
The order will get the “Partially paid” payment status the maximum amount available for the refund being specified:
