 Add the above URL after you modified it with your settings into the **URL** field. Remove the line breaks as they are only there to make the URL readable here.
 
+- Make sure to check the `Use POST method` checkbox.
 - It's HIGHLY recommended to use SSL/TLS.
 - Use the domain that Home Assistant is available on the internet (or the public IP address if you have a static IP address). This can be a local IP address if you are using an always on VPN from your mobile device to your home network.
 - Only remove `PORT` if your Home Assistant instance is using port 443. Otherwise set it to the port you're using.
 - For Home Assistant only the above URL, as written, will work - do not add, remove, or change the order of any of the parameters.
-- Add `Authorization: Bearer LLAT` to the HTTP Headers setting (replace `LLAT` with your Long Lived Access Token).
 - You can change the name of your device name by replacing `&device=%SER` with `&device=DEVICE_NAME`.
