To create a Payer object for a User, you will send a POST request with a request body represented in the sample below*. Since, just like in the real world, a customer may have a number of accounts from which to make payments, Users can have multiple Payers. The PayerId that is returned with a successful API call can be used to specify the source of funds when making a payment.
*NOTE: all fields within bankAccountDetails object are mandatory because they are required by the loan servicers themselves
