var Dialog = require('dialog-api/lib/messenger');

var app = express();

// ...
app.post('/webhook', function(req, res) {
  dialog.incoming(req.body);

  var messagingEvents = req.body.entry[0].messaging;

  if (messagingEvents.length && messagingEvents[0].message) {
    var event = req.body.entry[0].messaging[0];

    var payload = {
      recipient: {
        id: event.sender.id
      },
      message: { text: 'Hey human!' }

bot.outgoing(function(message, next) {
  dialog.outgoingMiddleware(message, next)
})

Events

Send events to Dialog to keep track of your custom logic. Optionally pass an Interlocutor's distinct id to tie the event to one of your bot's interlocutors. See docs.dialoganalytics.com/reference/event#create

dialog.event('subscribed', 'interlocutorDistinctId', { custom: 'value' })

Clicks

Record clicks by interlocutors inside a conversation using a trackable link. For every links that needs to be tracked, generate a trackable URL by passing the interlocutor's distinct Id (provided by the platform or provider) and the url to the link method. See docs.dialoganalytics.com/reference/click-tracking

dialog.link('http://example.com', interlocutorDistinctId)
// https://api.dialoganalytics.com/v1/b/7928374/clicks/?id=123456&url=http%3A%2F%2Fexample.com

Attach

Modify the current track payload about to be sent to Dialog's API with this helper method.

For example, you can specify a message name:

dialog.attach('welcome')
dialog.attach({ message: { name: 'welcome' }}) // equivalent

This will modify the track payload:

{
  message: {
    name: "welcome",
    ...
  },
  conversation: { ... },
  creator: { ... }
}
