# WordPress Site Domains

With the `domains` endpoint, you can:

* Use a `POST` request to [add a new domain](https://kinsta.com/docs/wordpress-hosting/wordpress-domains) to a WordPress site
* Use a `DEL` request to remove a domain.
* Use a `PUT` request to [change the primary domain](https://kinsta.com/docs/wordpress-hosting/wordpress-domains/#change-your-primary-domain).

You can obtain the `environment_id` and `domain_ids` using the `GET` request with the [WordPress Site Environments](https://api-docs.kinsta.com/tag/WordPress-Site-Environments#operation/getSiteEnvironments) endpoint.

The `environment_id` is also shown after the `site_id` in the URL in MyKinsta when you access the environment, for example in the URL `https://my.kinsta.com/sites/details/fbab4927-e354-4044-b226-29ac0fbd20ca/c84ce214-69b9-4a32-8e67-880672cf1d38?idCompany=bdd25d71-5706-4890-870f-1adda17c505d`:

* The `site_id` is `fbab4927-e354-4044-b226-29ac0fbd20ca`
* The `environment_id` is `c84ce214-69b9-4a32-8e67-880672cf1d38`
* The `company_id` is `bdd25d71-5706-4890-870f-1adda17c505d`
