@ldez I would appreciate it if you could look at this. 😉

@marcusgrando I have some doubts, based on your API documentation:
https://api.azion.com/#ba265bc9-82a9-4ec9-b5ca-2199a1ea0f40

{
  "count": 1,
  "links": {
    "previous": null,
    "next": null
  },
  "total_pages": 1,
  "results": [
    {
      "domain": "youdomain.com",
      "is_active": true,
      "name": "New Hosted Zone via API POST method",
      "id": 1234
    }
  ],
  "schema_version": 3
}

The field name is a random string, and the field domain is the domain.

Can you confirm that?

[marcusgrando]

Yes, you are right. A name is just any given name that describes the domain, and the domain is exactly the FQDN.

[ldez]

ok so the existing implementation was wrong. I fixed that.
