trigger newMYOBcard on Card__c (before insert) {
/*
The purpose of this trigger is to callout to the MYOB API to create a new card record that mirrors
the SF Custom Object Cards. There are 4 different card types in MYOB of which 3 are currently supported by
our bespoke customisation - [Personal, Supplier and Customer]. The fields applicable to the different record types
include some fields that are common to all record types;some fields that are common to some record types and some
fields that are unique to a record type. The different field groupings have been identified by SF fieldsets.
The Personal fieldset contains fields common to ALL record types;
The Base (Card) fieldset contains fields common to Customer and Supplier record types;
The Supplier fieldset contains fields unique to the Supplier record type;
The Customer fieldset contains fields unique to the Customer record type;

The API requires a JSON object contain field:value pairs for all the Card object fields
for the matching record type. I have made the API field name match the API requirements so only the '__c' suffix
needs to be removed. This could be done by using a System.JSON serialize method and then trimming off the 
'__c' suffix or using the System.JSONGenerator class methods. Either way there will be no need to individually map
SF fields to MYOB API fields.
