IT:AD:PostMan:HowTo:Test WCF Endpoints

• Started the WCF service endpoint project:
• I used WCFTestClient.exe to get the following snippet from the XML tab:

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header>
    <Action s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">http://tempuri.org/IService1/GetData</Action>
  </s:Header>
  <s:Body>
    <GetData xmlns="http://tempuri.org/">
      <value>0</value>
    </GetData>
  </s:Body>
</s:Envelope>

• Start Postman
• Set the following:
  • format set to Raw
  • verb=POST
  • Headers:
    • Content-Type=text/xml; charset=utf-8

      • SOAPAction=http://tempuri.org/IService1/GetData

      * Had to edit the soap snippet to remove the action's namespace¹⁾, or atleast edit it's namespace²⁾:

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header>
    <!-- had to remove the Action header's namespace before I stopped getting 400's -->
    <Action s:mustUnderstand="1">http://tempuri.org/IService1/GetData</Action>
    <!-- added a custom header -->
    <currentCulture>en-US</currentCulture>
  </s:Header>
  <s:Body>
    <GetData xmlns="http://tempuri.org/">
      <value>0</value>
    </GetData>
  </s:Body>
</s:Envelope>

The reason the above need fiddling is because the protocol used – basicHttpBinding – is set to accept no Headers (notice the none in http://schemas.microsoft.com/ws/2005/05/addressing/none).
