BILLING Country Code is invalid (Rest V2)

Hi Guys,

I’m getting the following error:

{
            "code": 400,
            "message": "BILLING Country Code is invalid",
            "status": "Bad Request",
            "details": [
                {
                    "domain": "Contacts",
                    "resource": "PATCH /rest/v2/contacts/{contact_id}"
                }
            ]
        }

When posting:

            "addresses": [
                {
                    "field": "BILLING",
                    "line1": "ADDRESS LINE 1",
                    "line2": null,

                    "country_code": "US"
                }
            ],
            "email_addresses": [
                {
                    "email": "EMAIL@yahoo.com",
                    "field": "EMAIL1",
                    "opt_in_reason": "Purchased Product"
                }
            ],
            "family_name": "FIRST",
            "given_name": "LAST"
        }

The v2 APIs conform to ISO3 validation:

So just changing US to USA should fix your issue.
