To connect the Rasa core to any messaging platform we use inputchannel or outputchannel for example to connect the Rasa core to facebook we use inbuilt connector like that For Google’s assistant

from __future__ import absolute_import
from __future__ import division
from __future__ import print_function
from __future__ import unicode_literals

import logging

from flask import Flask, Response, Blueprint, request, jsonify
from import UserMessage, OutputChannel
from import InputChannel
from import CollectingOutputChannel
import json	

logger = logging.getLogger(__name__)

class GoogleConnector(InputChannel):
    """A custom http input channel.

    This implementation is the basis for a custom implementation of a chat
    frontend. You can customize this to send messages to Rasa Core and
    retrieve responses from the agent."""

    def name(cls):
        return "google_home"

    def blueprint(self, on_new_message):
        google_webhook = Blueprint('google_webhook', __name__)

        @google_webhook.route("/", methods=['GET'])
        def health():
            return jsonify({"status": "ok"})

        @google_webhook.route("/webhook", methods=['POST'])
        def receive():
            payload = json.loads(		
            sender_id = payload['user']['userId']
            intent = payload['inputs'][0]['intent'] 			
            text = payload['inputs'][0]['rawInputs'][0]['query'] 		
            if intent == 'actions.intent.MAIN':	
                message = "<speak>Hello! <break time=\"1\"/> Welcome to the Rasa-powered Google Assistant skill. You can start by saying hi."			 
                out = CollectingOutputChannel()			
                on_new_message(UserMessage(text, out, sender_id))
                responses = [m["text"] for m in out.messages]
                message = responses[0]	
            r = json.dumps(
                  "conversationToken": "{\"state\":null,\"data\":{}}",
                  "expectUserResponse": 'true',
                  "expectedInputs": [
                      "inputPrompt": {
                       "initialPrompts": [
                          "ssml": message
                    "possibleIntents": [
                      "intent": "actions.intent.TEXT"
            return r				
        return google_webhook
