Using PowerShell to query CRM 2011 SOAP endpoint – Answer!

Big thanks to @JLattimer. He helped me figure our the error in my SOAP envelope.

In my last post, I was trying to retrieve FullName from Crm 2011’s web services via PowerShell. Below is the code to do that.

$xml = "<?xml version='1.0' encoding='utf-8'?>"
$xml += "<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'>"
$xml += "<soap:Body>"
$xml += "<Retrieve xmlns='http://schemas.microsoft.com/xrm/2011/Contracts/Services'>"
$xml += "<entityName>contact</entityName>"
$xml += "<id>12345678-1234-1234-1234-123456789012</id>"
$xml += "<columnSet xmlns:q1='http://schemas.microsoft.com/xrm/2011/Contracts' xsi:type='q1:ColumnSet'>"
$xml += "<q1:Columns xmlns:c='http://schemas.microsoft.com/2003/10/Serialization/Arrays'>"
$xml += "<c:string>fullname</c:string>"
$xml += "<c:string>telephone1</c:string>"
$xml += "</q1:Columns>"
$xml += "</columnSet>"
$xml += "</Retrieve></soap:Body></soap:Envelope>"
