Mule 4 introduced APIKit for soap webservice. It is very similar to APIKit for Rest. In SOAP APIKit, it accepts WSDL file instead of RAML file. APIKit for SOAP generates work flow from remote WSDL file or downloaded WSDL file in your system.

To create SOAP APIKit project, First create Mulesoft project with these steps in Anypoint studio.

Under File Menu -> select New -> Mule Project

In above pic WSDL file gets selected from local folder to create Mule Project.

Once you click finish, it generates default APIKit flow based on WSDL file.

In this Mulesoft SOAP APIKit example project, application is consuming SOAP webservice and exposing WSDL and enabling SOAP webservice.

In SOAP Router APIKit, APIKit SOAP Configuration is defined WSDL location, Services and Port from WSDL file.

In above configuration, “soapkit-config” SOAP Router look up for requested method. Based on requested method it reroutes request from api-main flow to method flow. In this example, requested method is “ExecuteTransaction” from existing wsdl, so method flow name is

<flow name=“ExecuteTransaction:\soapkit-config”>  

In this example we are consuming same WSDL but end point is different.

To call same WSDL we have to format our request based on WSDL file. In dataweave, create request based on WSDL and sending request through HTTP connector.

Here is dataweave transformation to generate request for existing WSDL file

     	  }
     	
    	}

}
