Any Idea what to do with url files that come from The Canva data portal API

unknown

Hello,

I am experimenting with the Canvas data portal API and was successfully able to use it. The program that I made spits out the file URL link (Code below and is PowerShell).

$url = "https://portal.inshosteddata.com/api/account/self/file/byTable/assignment_fact"$API_key = "insert key"$secret = "insert secret"function _url {param($url,$secret)function buffer { param ($string) $c=@() Foreach ($element in $string.toCharArray()) {$c+= [System.Convert]::ToSByte($element)} return $c}#create url$combo = "(\w+\:\/\/)?(\w+\.\w+\.\w+)([\/\w+]+)?((\?)([\w\=\&]+))?"$regex = New-Object System.Text.RegularExpressions.Regex($combo,[System.Text.RegularExpressions.RegexOptions]::None)$groups=$regex.Match($url).Groups$protocol= $groups[1].value$host_url=$groups[2].value$pathname = $groups[3].value$href = $groups[0].value$query=$groups[6].value#create timestamp$time = Get-Date$time = $time.ToUniversalTime()$timestamp = $time.GetDateTimeFormats()[103]#create message$message = "GET`n$host_url`n`n`n$pathname`n$query`n$timestamp`n$secret"$hmacsha = New-Object System.Security.Cryptography.HMACSHA256$hmacsha.key = buffer -string $secret$signature = $hmacsha.ComputeHash([Text.Encoding]::UTF8.GetBytes($message))$signature = [Convert]::ToBase64String($signature)#create hashreturn @{"protocol"= $groups[1].value;"host"=$groups[2].value; "pathname" = $groups[3].value; "href" = $groups[0].value;"query"=$groups[6].value"timestamp" = $timestamp;"message" = $message;"secret" = $secret;"_groups" = $groups;"signature" = $signature }}function call_canvas{param($API_key, $url_object)$header = @{"Authorization"="HMACAuth "+ $API_key+":"+$url_object.signature; "Date" = $url_object.timestamp.ToString() }$purlly=Invoke-WebRequest -Headers $header   -Method Get   -Uri $url_object.href return ConvertFrom-Json $purlly.Content}$url_object = _url -url $url -secret $secret$chubb =call_canvas -API_key $API_key -url_object $url_object

When I call $chubb.history[0].files.url I get this very long string (it doesn't work)

"https://hosted-data-work.s3.amazonaws.com/20161121T220310.324/dw_split/dddd/asignment_fact/part-00101.gz?AWSAccesKeyId… "

My question is what do I have to do to get the file at this point. I know If just copy and paste the link in a website it will download but if I call it with an invoke web request I just get a 403 error.
