How do I adjust a charge on a form that has already been submitted?

I created a registration form for our school and a price was incorrect when it went live. I need to reach out to the folks who already registered and let them know the price increase and then I need to adjust their total that was charged. Can I do that?

You may edit your form to change the price. However, it is not possible to adjust the payment  as we are using Integrations to process payments. Also, the Payment tool is blocked when you edit the submission.

Hope this information helps.
