This script was originally forked from https://github.com/markafox/GoDaddy_Powershell_DDNS and heavily modified for 
my own internal use. This works great for me. Your mileage may vary.

This script is used to check and update your GoDaddy DNS server to the IP address of your current internet connection.

First go to GoDaddy developer site to create a developer account and get your key and secret

https://developer.godaddy.com/getstarted
 
Update the first 4 varriables with your information
 
#>
# This data is now in the include file
#$domain = 'your.domain.to.update'  # your domain
#$name = 'name_of_host' #name of the A record to update
#$key = 'key' #key for godaddy developer API
#$secret = 'Secret' #Secret for godday developer API
. .\update_gd_dns_cfg.ps1
$headers = @{}
$headers["Authorization"] = 'sso-key ' + $key + ':' + $secret
$result = Invoke-WebRequest https://api.godaddy.com/v1/domains/$domain/records/$type/$name -method get -headers $headers -UseBasicParsing
$content = ConvertFrom-Json $result.content
$dnsIp = $content.data
# Get public ip address there are several websites that can do this.
$currentIp = Invoke-RestMethod http://ipinfo.io/json | Select-Object -ExpandProperty ip
echo "CurrentIP: $currentIp"
if ( $currentIp -ne $dnsIp ) {
    $Request = @(@{data=$currentIp;port=$port;priority=0;protocol="string";service="string";ttl=$ttl;weight=$weight })
    $JSON = Convertto-Json $request
    $result = Invoke-WebRequest https://api.godaddy.com/v1/domains/$domain/records/$type/$name -method put -headers $headers -Body $json -ContentType "application/json" -UseBasicParsing
}
if ( $currentIp -eq $dnsIp ) {
    echo "IP's are equal, no update required"
}
