Script to update a Google Domains DNS record

google-domains-dynamic-dns-update.sh

#!/bin/bash

### Google Domains provides an API to update a DNS "Syntheitc record". This script
### updates a record with the script-runner's public IP, as resolved using a DNS
### lookup.

### Google Dynamic DNS: https://support.google.com/domains/answer/6147083
### Synthetic Records: https://support.google.com/domains/answer/6069273

USERNAME=""
PASSWORD=""
HOSTNAME="yoursubdomain.yourdomain.here"

# Resolve current public IP
IP=$( dig +short myip.opendns.com @resolver1.opendns.com )
# Update Google DNS Record
URL="https://${USERNAME}:${PASSWORD}@domains.google.com/nic/update?hostname=${HOSTNAME}&myip=${IP}"
curl -s $URL

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.com

For more details see the section at the bottom of this page labelled "Using the API to update your Dynamic DNS record"

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

https://username:password@domains.google.com/nic/update?hostname=subdomain.yourdomain.com

A stare is born

Does anyone know if there is an update to this to work with Squarespace since Google Domains has retired?

Squarespace does not offer an API for DNS configuration. There is no practical mechanism to programmatically manage dynamic DNS records for domains they manage.

I’m a bit confused why you need DDNS for squarespace? Isn’t that a static address? I recommend transferring your domains over to cloudflare. They do have an API you can use. I found a project called DDClient on GitHub that you can run every hour to update your record.

Squarespace has a registrar & DNS business, independent of their hosting services: https://domains.squarespace.com

Squarespace purchased all Google Domains registrations: https://support.google.com/domains/answer/13689670

Any users whose domain registrations were transferred with the purchase would need to find a new registrar if they want a DDNS API.
