Import a packaged workflow via API PowerShell Script

Hi ​@doorga,

I tested this on a machine running Windows 11, and it worked. Update the token and filepath/name, and you are good to go.
 

# Load System.Net.Http (needed for PS 5.1)
Add-Type -AssemblyName System.Net.Http

# === CONFIGURATION ===
$apiUrl = "https://us.nintex.io/workflows/v1/designs/package/import"
$token = "YourToken"  # Replace with your token
$packagePath = "C:\workflow-export.zip" # Update path
$workflowName = "Imported Workflow"
$assignedUse = "Development"    # Or "Production"
$overwriteExisting = $true
$publishWhenConfigured = $false

# === HELPER: URL-encode ===
function Encode-UriComponent {
    param([string]$str)
    return [uri]::EscapeDataString($str)
}

# === BUILD QUERY STRING (encoded) ===
$queryParams = @{
    name = $workflowName
    assignedUse = $assignedUse
    overwriteExisting = $overwriteExisting
    publishWhenConfigured = $publishWhenConfigured
}

$queryString = ($queryParams.GetEnumerator() | ForEach-Object {
    "$(Encode-UriComponent $_.Key)=$(Encode-UriComponent $_.Value)"
}) -join "&"

$uri = "$apiUrl`?$queryString"

Write-Host "Request URI:" $uri -ForegroundColor DarkGray

# === PREPARE HTTP CLIENT ===
$handler = New-Object System.Net.Http.HttpClientHandler
$client = New-Object System.Net.Http.HttpClient($handler)
$client.DefaultRequestHeaders.Authorization = New-Object System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", $token)
$client.DefaultRequestHeaders.Accept.Add([System.Net.Http.Headers.MediaTypeWithQualityHeaderValue]::new("application/json"))

# === BUILD MULTIPART FORM DATA ===
$content = New-Object System.Net.Http.MultipartFormDataContent
$fileStream = [System.IO.File]::OpenRead($packagePath)
$fileContent = New-Object System.Net.Http.StreamContent($fileStream)
$fileContent.Headers.ContentType = [System.Net.Http.Headers.MediaTypeHeaderValue]::Parse("application/zip")
$content.Add($fileContent, "workflowDeploymentPackage", [System.IO.Path]::GetFileName($packagePath))

# === SEND REQUEST ===
Write-Host "`nUploading package '$packagePath' to Nintex..." -ForegroundColor Cyan

try {
    $response = $client.PostAsync($uri, $content).Result
    $body = $response.Content.ReadAsStringAsync().Result

    if ($response.IsSuccessStatusCode) {
        Write-Host "`n✅ Import successful!" -ForegroundColor Green
        try {
            $json = $body | ConvertFrom-Json
            $json.workflows | Format-List
        } catch {
            Write-Host "Response:" $body
        }
    } else {
        Write-Host "`n❌ Import failed: $($response.StatusCode)" -ForegroundColor Red
        Write-Host "Response body:"
        Write-Host $body
    }
}
catch {
    Write-Host "`n❌ Exception:" $_.Exception.Message -ForegroundColor Red
}
finally {
    if ($fileStream) { $fileStream.Dispose() }
    if ($client) { $client.Dispose() }
}
