Invalid country code and region - What IS valid?

Got the same problem here in Australia.

Region is only accepting full name of the state.
For example I have to use “Victoria” instead of “VIC”.

  1. When I’m operating on InfusionSoft web console and putting in a new contact, “VIC” is allowed to be saved in region field. But why API can’t do it ?
  2. Secondly, when I got “Victoria” saved on new contact, InfusionSoft web console shows “AU-VIC” in the field. Why that value has been saved differently.

Found the answers from here:
