Rasa Human handoff using Socket Programming and API

Sorry For Tkinter 😊

For Clarification

User → Customer
Admin → Customer Care
Bot → RASA Bot

There are many ways to Handle or make connection between User and Admin some are:

• Using Rasa Action Server
• Using custom backend and frontend for your chat Interface
• Rasa Action Server + Frontend Command Change or Button change

In this Repository we have opted for second option

Task happen

• connection is stablised between User and Bot-server.
• User asked for Human intervention.
• We create a Intent for recognizing Wheather User is asking for Human Handoff.
• A custom action is attached to that intent and that can be our Trigger message.
• or if you are looking for third option then We can handled it using a custom message and CoversationPaused() using Action Server, here custom message can be Trigger message.
• Don't worry about conversation paused, as we will be not forwarding any message to bot server after the Trigger message.
• After trigger we can stablised connection between User and Admin.

if ast.literal_eval(x.text)[0]["text"] == "Human Handoff":
        conversation.append('Bot: Admin is connecting please wait for few minutes')
        conversation.append('Admin: Hello i am your admin. How can i help you')
        text.set("\n".join(conversation))
        label.update()
        func()
        sendmessagebutton.configure(text = "Human send",command=sendmessage)

Here Human Handoff is our trigger message, when our user interface recevied this message it will throw response and change the function related to the button. You can do it using flag also.

• Now a connection is stablised between Admin and User, and there is no intervention of Bot as we are not forwarding any message to it.
• Now Admin and User can have a Normal Chat.
• We have created a list of the previous message that can be send as form of packet, so that Admin can know the previous chat with Bot and User.
