PowerShell Invoke-WebRequest error with Go Daddy API - api

Question

Following a script (from here) that many others have suggested works OK, I am having an error that is just outside my ability to understand. I am novice-to-intermediate with Power Shell and just beginning with API's.
The script is:
$domain = 'example.com' # your domain
$name = 'xyz' # name of the A record to update
$key = 'myKey # key for godaddy developer API
$secret = 'mySecret' # Secret for godday developer API
$headers = #{}
$headers["Authorization"] = 'sso-key ' + $key + ':' + $secret
$result = Invoke-WebRequest https://api.godaddy.com/v1/domains/$domain/records/A/$name -method get -headers $headers
$content = ConvertFrom-Json $result.content
$dnsIp = $content.data
# Get public ip address
$currentIp = Invoke-RestMethod http://ipinfo.io/json | Select -exp ip
# THE CODE WORKS FINE UP TO HERE
if ( $currentIp -ne $dnsIp) {
$Request = #{ttl=3600;data=$currentIp }
$JSON = Convertto-Json $request
# THE FOLLOWING LINE FAILS WITH THE ERROR NOTED BELOW
Invoke-WebRequest https://api.godaddy.com/v1/domains/$domain/records/A/$name -method put -headers $headers -Body $json -ContentType "application/json"
}
The following error is returned for the final Invoke-WebRequest:
Invoke-WebRequest : {"code":"INVALID_BODY","fields":[{"code":"UNEXPECTED_TYPE","message":"is not a array","path":"records"}],"message":"Request body doesn't fulfill schema, see details in `fields`"}
At C:\tfsCode\tfs\api.ps1:25 char:5

The Go Daddy reference page for the Get API is here and for the Put API is here.

Answer 1

The PUT API documentation says it’s expecting the body to be an array. This is also what the error message is saying. Try changing this line:
$Request = #{ttl=3600;data=$currentIp }
to
$Request = #(#{ttl=3600;data=$currentIp })
#() creates an array in PowerShell, when converted to JSON it will still be an array
#{} creates a hashtable in PowerShell, when converted to JSON it will be an object
