I want to know how do I get Watson to send something in the conversation. I saw some examples and tried and it did not work. Can someone help?

I dont now If I'm doing right, but My example is: 

// var responseText = null;
   //responseText = {};
 var latestResponse = Api.setResponsePayload(); // I dont know if this is true
  var context = latestResponse.context;
  Api.sendRequest('Hi ' + context); // I try this
  responseText = 'Hi ' + context; // I try this too

This is what i want:

Did you check the demo app at https://github.com/watson-developer-cloud/conversation-simple ?

You can add objects to the context in a JSON way.

context.myproperty = "Hello World";

And send this with the input to the service

The other way around, inside the conversation service, you can assign a variable (in this case username) to the text provided in the previous step (in this case input.text). By using $variablename (in this case $username) you can generate a dynamic response. Don't let the order in the advance response screen disturb you, context is processed before output...

enter image description here

In the client (in my case Java)

MessageRequest.Builder messageRequestBuilder = new MessageRequest.Builder();
        messageRequestBuilder.inputText("Joe");
        messageRequestBuilder.context(question.context); //this context comes from a previous step 


ServiceCall<MessageResponse> response = conversationService.message(workspaceId, messageRequestBuilder.build());
        MessageResponse mAnswer =  response.execute();

        Object textObject = mAnswer.getOutput().get("text");

This textObject will contain: Hi Joe, nice to meet you. I am here to answer questions about....

(Node.) JS code copied (and removed some lines ) from the sample app

// Create the service wrapper
var conversation = watson.conversation ( {
  username: process.env.CONVERSATION_USERNAME || '<username>',
  password: process.env.CONVERSATION_PASSWORD || '<password>',
  version_date: '2016-07-11',
  version: 'v1'
} );


// Endpoint to be called from the client side
app.post ( '/api/message', function (req, res) {

  var payload = {
    workspace_id: workspace_id,
    context: {}
  };
  if ( req.body ) {
    if ( req.body.input ) {
      payload.input = req.body.input;
    }
    if ( req.body.context ) {
      // The client must maintain context/state
      payload.context = req.body.context;
    }
  }
  // Send the input to the conversation service
  conversation.message ( payload, function (data) {
    return res.json ( data );
  } );
