How can Supporters update their credit cards?

Supporters can update their payment methods, as well as other details of their recurring plan in the Donor Portal. If an installment ever fails, they can also be automatically sent the Installment failed email template which includes a button to take them to the screen of Donor Portal where they can update their payment method.

Please also be aware that as long as Virtual Terminal is enabled, you also can update credit cards on supporters' behalf while on the recurring plan record screen in the dashboard.
