Everything Fiat

This section will describe how fiat flows in/out of the fortress system and also touch on how payment methods are created. We'll also include sections related to risk and timing to give you a full picture of how fiat is handled in the system and how best to work with your applications.

What are payment methods(externalAccounts)?

Payment methods are persistent objects linked to an identity that references a connected bank account/credit card. For instance, Fortress utilizes MX to connect end users to their bank accounts, allowing them to interface directly with their bank. Once the setup flow is complete, you are returned an id that can be used to create this persisted object. When making a payment, depositing, or buying crypto, you can then reference that particular bank account id for funding of the good/service.
