Introduced REST Version 2.0

REST Version is defined by passing an optional value in the header attribute ‘ApiVersion’.
When no option is provided the REST call will default to version 1.0.
● Version2.0 supports sending Custom Attributes using the new “Free Option” type.
● Sending Custom Attributes when using 2.0 has changed for non “Free Option”; versions so
review our Swagger UI before moving to version 2.0 if you are sending Custom Attributes
over REST.
