A customer object represents a customer (payor) of the merchant (payee). You must create a new customer or use an existing customer to perform a payment.
API endpoints allow you to create, delete, and update your customers, and fetch past payments. You can retrieve an individual customer, as well as a list of all your customers.
A customer can have multiple Credit Card and/or ACH (bank) Accounts objects. An account must be created a customer prior to collecting a payment.
