Events for the BotKit SDK

You can use the Kore.ai BotKit SDK to capture and handle events in the Bots Platform for better control and customization of the bot experience for users. The following events are supported by the BotKit SDK:

onMessage

This event consists of the following two components:

  • onUserMessage: This event is triggered when a user sends a message to Bot and it is received by the channel adapter. The user message is wrapped in this event and sent to the SDK.
  • onBotMessage: This event is triggered when any messages need to be sent to the user. These messages are sent to the SDK along with context object.

onUserMessage

Syntax:

on_user_message : function(requestId, data, callback)

Parameters:

  • requestId – A unique ID for each message event.
  • payload – A JSON response payload as follows:
    {
       "message":"message sent by bot to the user",
       "taskId":"Dialog task Id",
       "nodeId":"current node id in the dialog flow",
       "channel":"channel name",
       "context":"context object"
    }
  • callback – The function to call at event completion used to send the updated message and context back to the Bots Platform.

Example:
In the following code example for the onUserMessage event, the user message is evaluated for transfer to a live agent and transferred, otherwise, the message is passed on to the BotKit SDK for processing.

/*
 * OnUserMessage event handler
 */
function onUserMessage(requestId, payload, callback){
    debug("user message", payload);
    var visitorId = _.get(payload, 'channel.from');
	visitorId = payload.context.session.UserContext._id;
	var entry = _map[visitorId];
	if (payload.message === "clearagent") // disconnect from LiveChat on user utterance
	{
		sdk.clearAgentSession(payload);
	}
    if(entry){//check for live agent
        //route to live agent
        var formdata = {};
        formdata.secured_session_id = entry.secured_session_id;
        formdata.licence_id = config.liveagentlicense;
        formdata.message = payload.message;
        return api.sendMsg(visitorId, formdata)
            .catch(function(e){
                console.error(e);
                delete userDataMap[visitorId];
                delete _map[visitorId];
                return sdk.sendBotMessage(payload, callback);
            });
    }
    else {
        return sdk.sendBotMessage(payload, callback);
    }
}

onBotMessage

Syntax:

 on_bot_message : function(requestId, data, callback)

Parameters:

  • requestId – A unique ID for each message event.
  • payload – A JSON response payload as follows:
    {
       "message":"message sent to the user",
       "channel":"channel name",
       "context":"context object"
    }
  • callback – The function to call at event completion used to send the updated message and context back to the user.

Example:
The following code snippet onBotMessage event evaluates the user message for content and then for message tone. If the message tone is greater than or equal to 2 for the angry tone, then the bot communication between the user and the bot is switched to a live agent.

/*
 * onBotMessage event handler
 */
function onBotMessage(requestId, payload, callback){
    debug("Bot Message Data",payload);
	console.log("in bot message");
    var visitorId = _.get(paylod, 'channel.from');
    var entry = _map[visitorId];
    if(data.message.length === 0 || payload.message === '') {
        return;
    }
    var message_tone = _.get(payload, 'context.message_tone');console.log("message tone -----",message_tone);
    if(message_tone && message_tone.length> 0){
        var angry = _.filter(message_tone, {tone_name: 'angry'});
        if(angry.length){
            angry = angry[0];
            if(angry.level >=2){
              return  connectToAgent(requestId, data);
            }
        }
    }
    if(!entry)
    {
        sdk.sendUserMessage(payload, callback);
    }
}

onWebHook

This event is triggered when the Kore NL Engine processes the Webhook node in the dialog flow. This event is sent to the SDK with componentId and context. The SDK can execute business logic and send the updated context back to the platform.
Syntax:

on_webhook = function(requestId, componentId, payload, callback)

Parameters:

  • requestId – A unique ID for each webhook event.
  • componentId – The unique ID for the SDKWebhook node.
  • payload – A JSON response payload as follows:
    {
       "message":"message sent by bot to the Bots platform",
       "taskId":"Dialog task Id",
       "nodeId":"current node id in the dialog flow",
       "channel":"channel name",
       "context":"context object"
    }
  • callback – The function to call at event completion used to send the updated message and context back to the Bots Platform.

Examples
In the following example for the on_webhook event, two hotel names are returned as results as a response to user input.

    //on_webhook handler
    on_webhook  : function(requestId, payload, componentId, callback) {
        if (componentId === 'sendResponse') {
          var hotels = {
            "hotels":[
                  "Taj Banjara",
                  "Novotel"
            ]
          };
          payload.context.hotelResults = hotels;
          callback(null,data);
        }
    }

In this example for the on_webhook event, for the Flights Info node in a dialog task, either a list of departure or destination airports based on the requested date is returned based on the flow of the dialog, as a list of results displayed to the end user.

    on_webhook : function(requestId, payload, componentId, callback) {
        var context = payload.context;
	    if (componentName === 'FlightsInfo') {
		  var origin = context.entities.Source;
          var destination = context.entities.Dest;
          var departureDate = context.entities.Date;
          findFlights(origin,destination,departureDate)
			.then(function(flightResults) {
                payload.context.flightResults = flightResults;
				callback(null, data);
			});
	    } else if(componentId === 'GetSourceAirports'){
             var searchTerm = context.entities.SourceName;
             findAirports(searchTerm)
            .then(function(airportResults) {
                payload.context.sourceAirports = airportResults;
                callback(null, data);
            });
        } else if(componentId === 'GetDestAirports'){
           var searchTerm = context.entities.DestName;
             findAirports(searchTerm)
            .then(function(airportResults) {
                payload.context.destAirports = airportResults;
                callback(null, data);
            });
        }

onAgentTransfer

This event is triggered when the Kore NL Engine processes an Agent Transfer node in the dialog flow. This event is sent to the SDK with requestId and context. The SDK can execute a business logic to switch the user seamlessly to a Live Agent.
Syntax:

function onAgentTransfer(requestId, data, callback){
connectToAgent(requestId, data, callback);
}

Parameters:

  • requestId – A unique ID for each message event.
  • payload – A JSON response payload as follows:
    {
       OnAgentTransferPayload ","
          requestId ":1501244156289,"
          botId ":"st - b4a22e86 - e95b - 575 c - b888 - e106d083a251 ","
          callbackUrl ":"https: //bots.kore.ai/api/botsdk/stream/st-b4a22e86-e95b-575c-b888-e106d083a251/serviceCallback/1501244156289","context": ...
    }
  • callback – The function to call at event completion used to send the updated message and context back to the Bots Platform.

Example:
The following code snippet onAgentTransfer event connects the user to a Live Agent and passing the user message, bot message, and historical chat messages of the session.

function connectToAgent(requestId, data, cb){
var formdata = {}; console.log("userlog",JSON.stringify(data.context.session.UserContext._id));
formdata.licence_id = config.liveagentlicense;
formdata.welcome_message = "";
var visitorId = _.get(data, 'channel.channelInfos.from');
if(!visitorId){
visitorId = _.get(data, 'channel.from');
}
visitorId = data.context.session.UserContext._id;
userDataMap[visitorId] = data;
data.message="An Agent will be assigned to you shortly!!!";
var d = new Date();
data.context.session.BotUserSession.startTime = new Date().toLocaleString();
console.log("userlog",JSON.stringify(data.context.session));
sdk.sendUserMessage(data, cb);
formdata.welcome_message = "Link for user Chat history with bot: "+ config.app.url +"/history/index.html?visitorId=" + visitorId;
return api.initChat(visitorId, formdata)
.then(function(res){
_map[visitorId] = {
secured_session_id: res.secured_session_id,
visitorId: visitorId,
last_message_id: 0
};
});
}

Example:

on_event : function (requestId, data, callback)
{
return sdk.sendAlertMessage(data, callback);
}

The event adds the following code in the Data object sent to kit:

"event":
{
"event Type": "endDialog"/ “endFAQ”
}


		

OnAlert

This event is triggered when a bot user receives an alert.
Syntax:
on_alert : function (requestId, data, callback)
Parameters:

  • requestId – A unique ID for each message event.
  • data– A JSON response payload.
  • callback – The function to call at event completion; it is used to send the updated message and context back to the Bots Platform.

}

The alert response data is found in the data object sent to the kit.

OnVariableUpdate

This event is triggered on variable_update when Bot is published.

Syntax:
variable_update : function (requestId, data, callback)
Parameters:

  • requestId – A unique ID for each message event.
  • data– A JSON response payload
  • callback – The function to call after event completion; it is used to send the updated message and context back to the Bots Platform.

console.log("event----------->", event);
if (first || event == "variable_update") {
// fetch BotVariables List for published Bots
sdk.fetchBotVariable(data, langArr, function(err, response) {
dataStore.saveAllVariables(response, langArr);
first = false;
});
} else {
var lang = data.language;
//update Existing BotVariables in Storage
updateBotVariableInDataStore(botVariables, data, event, lang);
}
console.log(dataStore);

OnClientEvent

This event is triggered on client_event when Bot receives client events sent by the third party application.

Syntax:
on_client_event : function (requestId, data, callback)
Parameters:

  • requestId – A unique ID for each message event.
  • data– A JSON response payload
  • callback – The function to call after event completion; it is used to send the updated message and context back to the Bots Platform.
on_client_event : function (requestId, data, callback) {
    console.log("on_client_event -->  : ", data.preDefinedEvent, data.customEvent);
    return sdk.sendBotEvent(data, callback);
    }

These events are associated with the application subscribing to botkit event type – onMessage and onagenttransfer. These event can be used to track the events like user is typing, user has stopped typing or user has read the message.

Examples:

  • User started typing:
    Request:
    { “resourceid”: “/bot.clientEvent”,
    “preDefinedEvent” : { “type”: “TYPING_STARTED” },
