I'm not completely sure the second app's endpoint is listeing on localhost, actually given that you use a hostname it is not:

    <http:inbound-endpoint exchange-pattern="request-response" address="seconapp.co.io/flow" doc:name="HTTP"/>

You should try to change your first app outbound endpoint to:

    <http:outbound-endpoint exchange-pattern="request-response" host="seconapp.co.io" path="flow" port="8081" method="POST" doc:name="seconapp.co.io/flow"/>
