I would like the ability to create a custom field that is saved as part of the merchant record. So I could create a field called "carwash software" that is a dropdown and I could set what the dropdown options would be. Once the field is created, I would like it to automatically create a field that's in the API (which shows me the name and format so that if I'm an API customer, I can use that field to send and pull data from the API.
