return template response

I want to return a custom template response immediately for an apiProxy, when i receive a request on get uri /test/doc.

Some thing like success using html

@Popleys

Please be specific, what is your query here?

Well on the /test/doc uri/resource/conditonal flow you can add an Assign Message Policy on the response side and add the html code in the Payload.

<?xml version="1.0" encoding="UTF-8"?>
<AssignMessage async="false" continueOnError="false" enabled="true" name="Assign-Message-1">
   <DisplayName>Assign Message-1</DisplayName>
   <Properties />
   <Set>
      <Payload>
         <html>
            <body>Some thing like success using html</body>
         </html>
      </Payload>
   </Set>
   <IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables>
   <AssignTo createNew="false" transport="http" type="request" />
</AssignMessage>
