I had to change line 15 to IP=$( curl ifconfig.me ). Other than that the script works.

I know this is an old thread but you can just send a request to the URL and not include the IP just pass the username and password.
The API will then use the IP the request was sent from.
e.g.
curl https://username:password@domains.google.com/nic/update?hostname=subdomain.yourdomain.comFor more details see the section at the bottom of this page labelled "Using the API to update your Dynamic DNS record"
