-Make sure to include the API password if you have configured a password in Home Assistant (add `&api_password=<password>` to the end of the URL).

+- It's HIGHLY recommended to use SSL/TLS.
+- Use the domain that Home Assistant is available on the internet or the public IP address. Can be a local IP address if you are using a VPN setup.
+- Only remove `[Port]` if your Home Assistant instance is using port 80. Otherwise set it to 8123.
+- Click on **Parameters** in the app and you will see all available parameters for the URL. For Home Assistant only the above URL will work.
+- Make sure to include your [API password](/components/http/) if you have configured a password. Add `&api_password=[Your pasword]` to the end of the URL.
