Twilio Autopilot Conversation Flow?

Question

I'm current doing a thesis about chatbot survey (Created through code and able to gather information through dialog on facebook/slack). Currently I'm having a problem about conversation flow in Twilio.
To simplify the conversation:

• Chatbot: Hey do you mind answering a couple of question?
  
• Costumer: If yes proceed to ask question/ If no then thanks the costumer and stop the conversation.
  
  I used the example survey bot on Twilio Autopilot but it doesn't really have a "if/else" scenario. If Twilio doesn't have it then is there any other chatbot suitable for this?

Answer 1

It's actually pretty simple to do.

As @lizziepika mentioned, you have to utilize functions.

First, let's say you want to collect data from a question like so: TASKS Example

        {
        "actions": [
            {
                "collect": {
                    "name": "contact",
                    "questions": [
                        {
                            "question": "Are you a human?",
                            "name": "contact_human",
                            "type": "Twilio.YES_NO"
                        }
                    ],
                    "on_complete": {
                        "redirect": {
                            "method": "POST",
                            "uri": "https://Your_Twilio_Function_Domain.twil.io/Function_Name"
                        }
                    }
                }
            }
        ]
    }

On complete, the Autopilot will redirect to a Twilio Function.

A great example of a Twilio function for autopilot can be found here. https://github.com/twilio/autopilot-templates/blob/master/Functions/simple_response.js

I have tweaked it for our example.

    exports.handler = function(context, event, callback) {
        //we get the Memory from the answered questions.
        let memory = JSON.parse(event.Memory);
        //set up an array of object "actions" for the autopilot to continue.
        let actions = [];
        let responseItem;

        //get the answer from Memory
        let human = Memory.twilio.collected_data.contact.answers.contact_human.answer; //Yes or No

        if(human === "Yes"){
            responseItem = {
                "say": "ANSWER YES - You are human"
            };

            actions.push(responseItem);


        }else{
            responseItem = {
                "say": "ANSWER No - You are NOT human"
            };

            actions.push(responseItem);
        }

        responseItem = {
            "redirect": {
                "method": "POST",
                "uri": "task://next_task"
            }
        };

        actions.push(responseItem);

        let respObj = {
            "actions": actions
        };
        callback(null, respObj);
    };

The beauty of this is that you can have the function respond with anything that would be present in a task. You can have the function respond with questions, actions, redirects, etc, as long as the payload is the same form as Autopilot Tasks.

Twilio developer evangelist here.

You can do if/else using Autopilot with Twilio Functions, our serverless environment tool.

This Node.js quickstart has the first few steps you'd need to make a voice bot with Autopilot.

You could have one Autopilot task and then use a conditional in the Twilio Function the task redirects to to check what the user said. The Twilio Autopilot task could include this JSON:

{
    "actions": [
        {
            "redirect": {
                  "uri": "https://YOUR-TWILIO-FUNCTION-URL.twil.io/actions",
                  "method": "POST"
            }
        }
    ]
}

And then the Function may include

exports.handler = function(context, event, callback) {
    let responseObject = {};
    let memory = JSON.parse(event.Memory);
    console.log(memory.twilio.collected_data);
    let userInput = memory.twilio.collected_data.your_collect_function_name.answers.your_question_name.answer;
    console.log(num); //collected data from memory
    if(userInput == "pie") {
        //do whatever
    }
    else if (userInput == "cake") {
        // do something else
    }
    else {
        //do something else
    }
};

Let me know if this helps at all!
