How to Call Wcf Service Method from Postman

How to call WCF service method from POSTMAN

IIRC when you make SOAP calls to a WCF server, there are HTTP headers that have to be set in addition to the body content.

My old SOAP calls have headers of the form:

SOAPAction: http://domain/EndPoint

You may need to check this. If you have a working client, capture the traffic with Fiddler. Also, I have the content-type set to "text/xml; charset=utf-8" and I seem to recall that some servers are picky about the content-type on POST.

Test WCF Service using postman

This is because you visited the wrong URL, I suggest you enable the help document. Here is a demo:

        <endpointBehaviors>
            <behavior name="ESEndPointBehavior">
                <webHttp helpEnabled="true"/>
            </behavior>
        </endpointBehaviors>

You need to apply ESEndPointBehavior to the endpoint.

Then you can access the help document in your browser:

The help document includes the requested url, http verb and the requested format.

How to test wcf soap service using POSTMAN?

You have to pass a soap message to the service endpoint.

Eg

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:s="http://myNamespace/">
   <soapenv:Header/>
   <soapenv:Body>
      <s:request>
          ....
      </s:request>
   </soapenv:Body>
</soapenv:Envelope>

To get hold of a soap message you should use the service endpoint definition and use some tooling to generate a valid request.

Additionally, you should not be sending data to the endpoint address with ?wsdl as part of the address. It should only be the endpoint address.

How to call RestFul WCF POST service With Custom Object using POSTMAN or any client tool application?

Buddy, You are right, we should consider whether including the name of the parameter. Actually it is determined by the Bodystyle property.

[OperationContract]
        [WebInvoke(RequestFormat =WebMessageFormat.Json,ResponseFormat =WebMessageFormat.Json,BodyStyle =WebMessageBodyStyle.Bare)]
        CompositeType GetDataUsingDataContract(CompositeType composite);

    [DataContract]
    public class CompositeType
    {
        bool boolValue = true;
        string stringValue = "Hello ";

        [DataMember]
        public bool BoolValue
        {
            get { return boolValue; }
            set { boolValue = value; }
        }

        [DataMember]
        public string StringValue
        {
            get { return stringValue; }
            set { stringValue = value; }
        }
}

Depending on the above BodyStyle property, the request body is,

{"StringValue":"Hello","BoolValue":true}  

Please refer to my previous reply. There is a meticulous description in it.
