How to Post an Auto Message When Client Initiate Chat for The First Time?

There is a time when we want our chat system send a message, as if it were from a user who is about to use our chat for the first time. This feature is common in Facebook Messenger with its "Get Started" message or in Telegram with its "/start". So, how do we do that in Qiscus widget?

You could flag user whether it is his/her first time to use the chat and make use of "sendComment" method in "chatRoomCreatedCallback" to do send a message. Shown in a snippet code below for web SDK,

QiscusSDK.core.init({
  AppId: [your app id],
  options: {
    avatar: !0,
    loginSuccessCallback: function() {
      // Do something after successfully login
      // Chat with available user, need to be register first
      QiscusSDK.core.UI.chatTarget("qo@qiscus.com");
    },
    chatRoomCreatedCallback: function (room) {
      // if this is for the first time user is having chat, than send "hi" to SDK
      // as first trigger for bot
      if (first_chat) {
        var activeRoomId = QiscusSDK.core.selected.id;
        var today = new Date();
        var uniqueId = today.getTime();
        var messageText = 'Hi' // you can use any text to trigger bot to start a conversation
 
      // send comment to SDK
      QiscusSDK.core.sendComment(
        activeRoomId,
        messageText,
        uniqueId
      );
 
      // update first_chat value
      i['first_chat'] = false;
      localStorage.setItem("data", JSON.stringify(i))
     }
   }
 }
});
