I am trying to write a payment api at the moment, and was querying 'Settings
This is a critical part of the payment method, and needs some explaining. It represents the information the admin must fill in for this payment method to work. It will be different for each payment method. It is an array of arrays, with each inner array representing a field to be filled out. The structure of the inner array is similar to a html input element. It has a type, a value, and how to validate the value. For StormPay, we create four fields, as shown bellow.'

how can i work out what my processor (paymex) requires?
