Getting error - PowerShell script to CUCM / AXL API automation

[Chidananda S]

I am trying to build a script using Cisco AXL API and PowerShell.
When i try to run the below command i am getting error.



Invoke-RestMethod -Method Post -Uri "https://$cucmServer`:8443/axl/" -Headers @{'Content-Type'='text/xml';'SOAPAction'='CUCM:DB ver=' + $version} -Body $body -Credential $cred

CUCM version - 11.5
PowerShell version - 5.1.19041.1320


any guidance would be very helpful

I suspect you're not using powershell for SOAP correctly.  It looks like you're trying to use REST to perform the SOAP operation.  Here are a couple pages that explain how to use Powershell for SOAP you might find useful:

From the error message, it seems that AXL is not seeing the Authorization header credentials, or perhaps they are the incorrect ones.  After double checking the username/password are correct, another issue I've seen is some HTTP libraries will not (by default) proactively send the Authorization header but rather wait for a 404 and then re-send the request including credentials.  Usually there is an option/setting that allows you to force sending credentials on the first try.

FWIW, this is a PS sample that worked as of CUCM v10.5 (Windows 7):

[System.Net.ServicePointManager]::Expect100Continue = $false

$os = Get-WmiObject win32_operatingsystem

$body = @'
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://www.cisco.com/AXL/API/10.5">
   <soapenv:Header/>
   <soapenv:Body>
      <ns:doLdapSync sequence="1">
         <name>ADFS</name>
         <sync>true</sync>
      </ns:doLdapSync>
   </soapenv:Body>
</soapenv:Envelope>
'@

$pwd = ConvertTo-SecureString "ciscopsdt" -AsPlainText -Force
$cred = New-Object Management.Automation.PSCredential ('Administrator', $pwd)

$Result = Invoke-RestMethod -Method Post `
-ContentType "text/xml" -Body $body `
-Credential $cred `
-Uri https://ds-ucm105.cisco.com:8443/axl/
