Free Resource

Continue to drive demand for API management solutions that address the entire API life cycle and bridge the gap to microservices adoption.  Brought you to you in partnership with CA Technologies.

I will use WSO2 Developer Studio to write the custom mediator.

Click Developer studio tab and click open dashboard.








You can write the mediator logic in the following. 
Next create a carbon application project.

Next give the project name and select necessary dependencies.



Give a project name and click finish.

Next click "create archive"

Select the location (in file system) , Click 'OK'

Place the mediator (.car) to wso2esb-4.0.3/repository/deployment/server/carbonapps

The following code is a sample proxy service which will use a custom mediator
<proxy xmlns="http://ws.apache.org/ns/synapse" name="test" transports="https,http" statistics="disable" trace="disable" startOnLoad="true">
   <target>
      <inSequence>
         <class name="org.wso2.carbon.sample.FirstMediator" />
         <log level="full" />
         <send>
            <endpoint>
               <address uri="http://localhost:8282/services/SimpleStockQuoteService/" />
            </endpoint>
         </send>
      </inSequence>
      <outSequence>
         <send />
      </outSequence>
   </target>
</proxy>
