Upload Attachments using Rest API

[dhilip_ind]

Hi folks,

I have some issues with the Base64 encoded data, I was able to successfully upload the attachment to the archer record, however the Issue is with the attached files in the archer record.The Attached files are always getting corrupted and not coming exactly what I encoded. 

Here is my code: 

$path = "C:\Attachments\Test.pdf"
$content = Get-Content -Path $path
#$content
$bytes = [System.Text.Encoding]::UTF8.GetBytes($content)
$base64 = [System.Convert]::ToBase64String($bytes)
$base64
    $body_upload = @"
    {
    `"AttachmentName`": `"Test.pdf`",
    `"AttachmentBytes`": `"$base64`"
    }
"@    
$results = Invoke-RestMethod -Method POST -Uri $api_url -Headers $headers -Body $body_upload -ContentType "application/json"
     
     if ($results.IsSuccessful -and $results.ValidationMessages.count -eq 0) {
        $results.RequestedObject
        $File_ID = $results.RequestedObject.Id
      #  "File ID = " + $File_ID
    }
    else {
        $results.ValidationMessages
    }


    $file_body = "{
  `"Content`": {
    `"Id`": 462209,
    `"LevelId`": 62,
    `"Tag`": `"Findings`",
    `"FieldContents`": {
      `"16597`": {
        `"Type`": 11,
        `"Tag`": `"Attachments`",
        `"Value`": [$File_ID],
        `"FieldId`": 16597
      }
    }
  }
}"

$response = Invoke-RestMethod -Method PUT -Uri $contentupdate_url -Headers $headers -Body $file_body -ContentType "application/json"‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I wonder if the UTF8.GetBytes is causing the issue.

Thanks David. 

Found the issue. 

Changed 2nd line and it's working. 

$content = Get-Content -raw $path

Does  the attachment work with a user account only has the application access and the record permission? or does it need a sysadmin access to attach a file through an API?
