Hi Ftornero, thanks, can you share your experience? How can I write an Azure function to call eg. a NAV Page as a SOAP WebServicE?

Hello @Mathes ,

Assuming that you have published the page 21 as a webservice with the name Customer, this Azure function in Powershell call the webserice.

# POST method: $req
$requestBody = Get-Content $req -Raw | ConvertFrom-Json
$customer = $requestBody.customer

# GET method: each querystring parameter is its own variable
if ($req_query_name) 
{
    $name = $req_query_name 
}

function Execute-SOAPRequest 
( 
  [String] $SOAPRequest, 
  [String] $URL,
  [String] $SOAPAction 
) 
{ 
  write-host "Enviando petición SOAP al Servidor: $URL" 
  $soapWebRequest = [System.Net.WebRequest]::Create($URL) 

  $username = "user_name"
  $password = "password"
  $cred = New-Object System.Management.Automation.PSCredential -ArgumentList @($username,(ConvertTo-SecureString -String $password -AsPlainText -Force))
  $soapWebRequest.Credentials = $cred

  $soapWebRequest.Headers.Add("SOAPAction", $SOAPAction)
  $soapWebRequest.ContentType = "text/xml; charset=utf-8"
  $soapWebRequest.UserAgent   = "Microsoft ADO.NET Data Services"

  $soapWebRequest.Method      = "POST" 
  $soapWebRequest.Timeout = 800000         

  $writer = New-Object System.IO.StreamWriter $soapWebRequest.GetRequestStream();
  $writer.WriteLine($SOAPRequest);
  $writer.Close();      

  try {
    $resp = $soapWebRequest.GetResponse() 
    $responseStream = $resp.GetResponseStream() 
    $soapReader = [System.IO.StreamReader]($responseStream) 
    $ReturnXml = [Xml] $soapReader.ReadToEnd() 
    $responseStream.Close() 
    return $ReturnXml 
  } catch {
    Write-Error $Error[0]
  }
}

$url = "http://xx.xx.xx.xx:7047/DynamicsNAV/WS/COMPANYNAME/Page/Customer"

$soap = '<?xml version="1.0" encoding="utf-8"?>' + 
            '<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" ' + 
                            'xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ' +
                            'xmlns:xsd="http://www.w3.org/2001/XMLSchema">'+
            '<soap:Body>' +
                '<Read xmlns="urn:microsoft-dynamics-schemas/page/customer">' +
                  '<No>' + $customer +
                  '</No>'+
                '</Read>' +
            '</soap:Body>' +
            '</soap:Envelope>'


$action = '"urn:microsoft-dynamics-schemas/page/Customer"'

$ret = Execute-SOAPRequest $soap $url $action

[xml]$xml = $ret.InnerXML

$cust = $xml.Envelope.Body.Read_Result.Customer 

$hash = @{
          status = 200
         }

$customer_data = @{
             no   = $cust.No
             name = $cust.Name
             address = $cust.Address     
             city = $cust.City
             county = $cust.County
             post_code = $cust.Post_Code
             phone_no = $cust.Phone_No
}
    
$hash.add("customer", $customer_data)

$json = $hash | ConvertTo-Json    

Out-File -Encoding default -FilePath $res -inputObject $json

You need to pass a Json like this, in this case 29754 is de customer no.

{
    "customer": "29754"
}

In the Powershell script you need to change with real data this lines

  $username = "user_name"
  $password = "password"

  .....

  $url = "http://xx.xx.xx.xx:7047/DynamicsNAV/WS/COMPANYNAME/Page/Customer"

To use Powershell in the Azure function you need to activate this




And then you can create the Powershell function.
