<Callout type="info">
For the "urls" object, we no longer modify the `www` prefix of the primary URL. The API returns URLs exactly as the customer enters them, similar to the "url" field.
* If the customer saves a URL with `www`, the API returns it with `www`.
* If the customer saves a URL without `www`, the API returns it without `www`.
