I am attempting to create a script that creates/updates a policy and then uploads a file to the policy. So far, so good, but….

While referencing these scripts, in order:
Automox Console API Documentation | Create a New Policy
Automox Console API Documentation | Retrieve a Specific Policy
Automox Console API Docs | Upload Installation File,

and using Powershell (version 5.1.19041.1320) I am bumping into Parameter issues where...the last line of Upload Installation FIle.:

$response = (Invoke-WebRequest -Method Post -Uri $url -Headers $headers -Form $form).Content

Generates this error code: 

Invoke-WebRequest : A paramenter cannot be found that matches parameter name ‘Form’

I’m attempting for use the ‘Try It’ selection, the file uploads with no issue. So I am thinking there’s an issue with the command syntax itself. Any help?

Hey @jovann!

Looking at the documentation for Powershell 5 I do not see the Form argument available. I didn’t have Powershell 5 available to me, but you can try an implementation like this instead to work around the missing Form argument during file upload. Let us know how this works for you!


$apiKey = 'your api key goes here'

$url = "{id}/files"

$FilePath = 'path to your file goes here'

$fileBytes = [System.IO.File]::ReadAllBytes($FilePath)
$fileEnc = [System.Text.Encoding]::GetEncoding('UTF-8').GetString($fileBytes)
$boundary = [System.Guid]::NewGuid().ToString()
$LF = "`r`n"

$headers = @{
"Authorization" = "Bearer $apiKey"
"Content-Type" = "multipart/form-data; boundary=`"$boundary`""

$bodyLines = (
"Content-Disposition: form-data; name=`"file`"; filename=`"yourfile.pkg`"",
"Content-Type: application/octet-stream$LF",
) -join $LF

$response = (Invoke-WebRequest -Method Post -Uri $url -Headers $headers -Body $bodyLines).Content
