Add Complex Logic To A Twilio Whatsapp Bot - twilio

Question

I am developing a Whatsapp Bot in Twilio to collect survey data Covid-19 related. However, i want to add complex logic in my program task. For example, i only want to display a question asking if the user is pregnant or not if the user has selected female as her gender. Plus i want to add a range of the questions asking weight and height.
Below is the sample code for my task
"actions": [
{
"say": "Thank you for making the time for this survey. Your answers help us improve the service!"
},
{
"collect": {
"name": "csat_answers",
"questions": [
{
"question": "Have you completed this survey before??",
"name": "first_time",
"type": "Twilio.YES_NO"
},
{
"question": "Please enter your username",
"name": "usernmae"
},
{
"question": "How old are you?",
"name": "age",
"type": "Twilio.NUMBER"
},
{
"question": "What Gender are you",
"name": "Gender"
},
{
"question": "Are you pregnant?",
"name": "pregnant",
"type": "Twilio.YES_NO"
},
{
"question": "What is your height (cm)?",
"name": "height",
"type": "Twilio.NUMBER"
},
{
"question": "What is your weight (kg)?",
"name": "weight",
"type": "Twilio.NUMBER"
}
],
"on_complete": {
"redirect": {
"method": "POST",
"uri": "task://complete_survey"
}
}
}
}
]
}```

Answer 1

You will need to introduce logic in your Autopilot assistant, static JSON will not provide this capability.
How to Use Twilio Functions with Twilio Autopilot
If you are not a developer but a builder, you will want to look at Twilio Studio, to graphically draw out your survey flow and handle survey state.

There's no way to do conditional Collect flows in Autopilot so that logic would need to be a part of your app code. You can implement that conditional logic with Autopilot using Twilio Functions, our serverless environment tool for Node.js applications.
This Node.js quickstart has some of what you're looking for.
You could have one Autopilot task which redirects to the Function which would check what the user said. That Redirect task could include this JSON:
{
"actions": [
{
"collect": {
"name": "pregnant_collect",
"questions": [
{
"question": "Are you pregnant?",
"name": "pregnant",
"type": "Twilio.YES_NO"
}
],
"on_complete": {
"redirect": {
"method": "POST",
"uri": "https://YOUR-TWILIO-FUNCTION.twil.io/Function_Name"
}
}
}
}
]
}
and then use a conditional in the Twilio Function that above Task redirects to (above, it's https://YOUR-TWILIO-FUNCTION.twil.io/Function_Name) to check what the user said. The Twilio Autopilot task could include this JSON:
exports.handler = function(context, event, callback) {
//Memory from the answered question
let memory = JSON.parse(event.Memory);
//array of "actions" objects
let actions = [];
//response item to return/add to responseObject in Actions
let responseItem;
//get answer from Memory
let pregnant_answer = Memory.twilio.collected_data.pregnant_collect.answers.pregnant.answer;
//Yes or No
if (pregnant_answer === "Yes") {
responseItem = {
"say": "WHATEVER YOU WANT TO SAY FOR YES"
};
actions.push(responseItem);
}
else {
responseItem = {
"say": "WHATEVER YOU WANT TO SAY FOR NO"
};
actions.push(responseItem);
}
responseItem = {
"redirect": {
"method": "POST",
"uri": "task://next_task"
}
};
actions.push(responseItem);
let responseObject = {
"actions": actions
};
callback(null, responseObject);
};
Let me know if this helps at all! <3
