ChatBottle API for Node.js

ChatBottle is an engagement platform for your chatbots. ChatBottle allows to send personalized notifications to segmented groups of users.

The following platforms are currently supported via the npm package:

• Facebook Messenger

Setup Bot

Create a free account at https://chatbottle.co/ and get a ChatBottle token.

chatbottle is available via NPM.

npm install --save chatbottle-api-nodejs

Include chatbottle and create instance for each platform (if you have mor than one).

const chatbottleMessenger = require('./chatbottle')(process.env.CHATBOTTLE_API_TOKEN_MESSENGER, { platform: 'messenger' });
const chatbottleLine = require('./chatbottle')(process.env.CHATBOTTLE_API_TOKEN_LINE, { platform: 'line' });
...

You can enable debugging in the second parameter config if you have problems.

//@param config object {
//    platform => messenger, telegram,
//    debug => see every outgoing data,
//    debugRequest => to set the request-promise library to debug
//  }
const chatbottleMessenger = require('./chatbottle')(process.env.CHATBOTTLE_API_TOKEN_MESSENGER, { platform: 'messenger', debug: true, debugRequest: true });

Then log whenever your webhook is called.

Logging

Messenger

Facebook Messenger is directly supported to send the req.body directly to chatbottle if you enable the following events for your webhook:

https://developers.facebook.com/docs/messenger-platform/webhook-reference/message-echo https://developers.facebook.com/docs/messenger-platform/webhook-reference/message-delivered https://developers.facebook.com/docs/messenger-platform/webhook-reference/message-received https://developers.facebook.com/docs/messenger-platform/webhook-reference/message-read

app.post(webHookPath, function (req, res) {
    chatbottleMessenger.log(req.body);
    const messagingEvents = req.body.entry[0].messaging;
    if (messagingEvents.length && messagingEvents[0].message && messagingEvents[0].message.text) {
        const event = req.body.entry[0].messaging[0];
        const sender = event.sender.id;
        const text = event.message.text;
        const requestData = {
            url: 'https://graph.facebook.com/v2.6/me/messages',
            qs: { access_token: process.env.FACEBOOK_PAGE_TOKEN },
            method: 'POST',
            json: {
                recipient: { id: sender },
                message: {
                    text: 'ECHO: ' + text
                }
            }
        };
        request(requestData);
    }
    res.sendStatus(200);
});

Generic (Kik, Viber, Line, ...)

For generic bot platforms you have hook in every receiving and sending message.

// incoming
// lets say the incoming message is `event` (for Line Bot)
chatbottleLine.log({
    id: event.message ? event.message.id : event.timestamp,
    text: event.message.text,
    userId: event.source.userId,
    direction: 'In',
});

// outgoing
// you can listen on every outgoing request with monkey-patching (see below) ;)
chatbottleLine.log({
    id: new Date().getTime(),
    text: message, // if you have rich content, you can build your message on your own and JSON.stringify() it
    userId: to,
    direction: 'Out',
});
