API v2.5, API v1.4 is working as expected

Hey @timur​ Racheal from the support engineer team here👋🏼

I'm afraid the UTM parameters are no longer exposed on the Contact Model for our API versions 2.0+. In order to receive these from our API, you would have to roll back to v1.4 or earlier.

That being said, I will also pass this along as a feature request, so our engineers are aware you'd like to see these returned to the Contact model in future versions. And I know you're not the first to ask for this, so this will give it another bump on their radar.
