Rich messages
The Tiledesk native Widget supports many special messages that go beyond simple text sent back to the user.
A chatbot can also reply with images, videos, maps, buttons or even with a message embedding an entire interactive app (using iframes).
Fulfillment can benefit of all of these features, and sending a rich message to the client is very easy. You can use two ways to send rich messages:
- 1.
- 2.
In this tutorial we'll send back a message with a couple of text buttons to the widget
image
The Widget native protocol is a special JSON format that you can use to specify the message content, type (ex. 'image' or 'text'), attachments or other features.
In the next example we'll specify how to send a couple of text buttons to the Widget to let the user choose between a two options. If you want to know more about buttons and why they are useful in chatbot programming you can read Advanced chatbot styling: buttons in the Tiledesk's Knowledge Base.
We'll use the JSON format that you find in the Widget protocol, at the paragraph Text message with reply buttons
You can find the full index.js code of the Node.js application on the repl.it project for this tutorial:
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
app.use(bodyParser.json());
app.get('/', (req, res) => {
res.send('Tiledesk bot - rich messages!')
});
app.post('/bot', (req, res) => {
const intent = req.body.payload.intent.intent_display_name;
if (intent === 'start') {
res.json(
{
text: 'Do you agree?',
attributes: {
attachment: {
type:"template",
buttons: [
{
type: "text",
value: "Yes, I do"
},
{
type: "text",
value: "No, I don't"
}
]
}
}
}
);
}
});
app.listen(3000, () => {
console.log('server started');
});
Microlanguage is a special tag-based-language, specifically designed to allow chatbot developers to use advanced chatbot features without programming skills.
We just added another endpoint in the same index.js that you can use to understand how to use microlanguage to send buttons back to the widget.
app.post('/bot-micro', (req, res) => {
const intent = req.body.payload.intent.intent_display_name;
if (intent === 'start') {
res.json(
{
text: "Do you agree?\n* Yes, I do\n* No, I don't"
}
);
}
});
As you can see you just have to add the buttons with the same synthax you use for lists in markdown. The microlanguage automatically converts the items in buttons.
Disable microlanguage Microlanguage is by default enabled in fulfillment. If you want to disable it add the attributes.microlanguage = false option in the reply message:
res.json(
{
text: "Do you agree?\n* Yes, I do\n* No, I don't",
attributes: {
microlanguage: false
}
}
);
