customerDataType errors

[simpletix]

We use the latest .net Nuget package.

I added this code..

 var customer = new customerDataType 
            { 
                email = order.Email, 
                type = customerTypeEnum.individual, 
                id = order.Email 
            }; 

However, we started getting errors today.

Are there any constraints that we need to know about?

1. For example, do I have to set customer.id - is that required?
2. Does the email or id have to be unique?
3. Does the email or id have to be pre-registered?
4. Does the type have to be pre-set inside the merchants auth.net account?

Remove the type property and see what happens.
