Is there a way to call a WSO2 proxy service from a sequence?

Question

I am trying to collect data every minute from a REST API and send data to an MQTT Broker.

To realized this I've create a task and some sequences.

I have a sequence that retrieve the API Token from the Restfull API with credentials then call another sequence that call the Restfull API with the token to make a request to the API. The API then return my the result of the request.

I've manage to create a Proxy Service that send dummy data to an MQTT Broker, but I'm not able to call this Proxy Service after the Rest API return me the data.

How can I call the proxy service after the Token and the data is return to me?

I'm really new to WSO2 so if you know a better way to organize this process please feel free to share your knowledge.

I'm using WSO2 Entreprise Integrator 7.1.0, WSO2 Micro Integrator 1.2.0.

Thanks

The simplest way is to create sequence for send data to MQTT, like below, and call it.

<sequence xmlns="http://ws.apache.org/ns/synapse" name="send.mqtt">
   <property name="OUT_ONLY" value="true" scope="default" type="STRING"/>
   <property name="FORCE_SC_ACCEPTED" value="true" scope="axis2" type="STRING"/>
   <property name="target.endpoint" value="StockReqEndPoint"/>
   <send>
      <endpoint>
        <address uri="mqtt:/SampleProxy?mqtt.server.host.name=localhost&amp;mqtt.server.port=1883&amp;mqtt.client.id=esb.test.sender&amp;mqtt.topic.name=esb.test2&amp;mqtt.subscription.qos=2&amp;mqtt.blocking.sender=true"/>
      </endpoint>
   </send>
</sequence>
