Once an individual has applied for an Affirm loan and the terms have been set, changing the payment method may not be an option for that particular loan. Affirm typically connects directly to the payment method provided during the application process. However, if a person has upcoming payments, they may want to review their account settings on the Affirm website to see if they can update their payment method for future transactions or loans. It is essential to check the most current information on the Affirm website, as policies can vary based on the specific loan agreement and account status. For precise guidance tailored to individual situations, referring to the relevant sections on affirm.com is advisable.
