I am trying to create a very simple bot in skype with botframework using python.
Here are the steps i did.

• Created a channels bot in resources.

• Created a simple python web service using flask to receive the message from the bot. Exposed it over ngrok and added the same in the messaging endpoint.

• 
  

  I tested the bot from web chat and i am getting a json in my python webservice

  
  
  

  {
  
  "recipient": {
  
  "id": "txBot@b0X6R31x6uQ", 
  
  "name": "txBot"
  
   }, 
  
  "from": {
  
  "id": "1xFUIEqdQfv", 
  
  "name": "You"
  
   }, 
  
   "entities": [
  
      {
  
      "supportsTts": true, 
  
      "supportsListening": true, 
  
      "type": "ClientCapabilities", 
  
      "requiresBotState": true
  
      }
  
   ], 
  
  "locale": "en", 
  
  "timestamp": "2018-11-22T13:00:42.9086958Z", 
  
  "channelId": "webchat", 
  
  "channelData": {
  
  "clientActivityId": "1542891640077.5912976099256072.0"
  
  }, 
  
  "conversation": {
  
      "id": "b5b52b9e464b4e958b1219dadedfffce"
  
  }, 
  
  "serviceUrl": "https://webchat.botframework.com/", 
  
  "text": "hello from test", 
  
  "textFormat": "plain", 
  
  "type": "message", 
  
  "id": "b5b52b9e464b4e958b1219dadedfffce|0000002"
  
  }
  
  

  
  



• I am able to process this json and able to get the user input "hello from test" in this example to my webservice.

What i want to do is to return the same to my web chat bot from python.

I referred the below tutorial as well. I am able to post response back but i am not getting it in the bot.

python code of backend as below

import urllib

import json



import requests

import urllib2, json

from flask import Flask

from flask import request

from flask import make_response



# Flask app should start in global layout

app = Flask(__name__)





@app.route('/webhook', methods=['POST'])

def webhook():

    print "came inside"

    req = request.get_json(silent=True, force=True)

    print("Request:")

    print(json.dumps(req, indent=4))

    service_url=""

    if req['type']=='conversationUpdate':

            return ''



    else:

            print "got input as : ",str(req['text'])

            payload = build_text_message_payload(req, req['text'])

            print "---- calling service url ----"

            #service_url = build_service_url2(req['serviceUrl'],req['conversation']['id'],req['id'])

            service_url = build_service_url2(req['serviceUrl'],req['conversation']['id'])





    print "---- Payload ----"

    print payload

    # where we are going to send our request

    print "---- Service url ----"

    print service_url

    # let's send the message

    response = send_to_conversation(service_url, payload)



    print "****************"

    print response

    # always return a response



    #print get_auth_token()



    return "success"







def build_text_message_payload(data, text):

    """Creates a text only message dict"""

    payload = {

    'type': 'message/text',

    'from': {

        'id': data['recipient']['id'],

        'name': data['recipient']['name'],

    },

    'recipient': {

        'id': data['from']['id'],



        'name': data['from']['name'],

    },

    'text': text,

}

    return payload













def build_service_url2(service_url, cid):

    """build the service url"""

    service_url = '{0}v3/conversations/{1}/activities'.format(

    service_url,

    cid

)

    return service_url



def send_to_conversation(service_url, payload):



  url="https://login.microsoftonline.com/botframework.com/oauth2/v2.0/token"

  headers1={'Content-Type':'application/x-www-form-urlencoded'}



  data=urllib.urlencode({'grant_type':'client_credentials','client_id':'jhxzxk1b2-1jjk-44b4-88bd-566d09crs4sg','client_secret':'lpfgrpDBPxjsLLFC41}@','scope':'https://api.botframework.com/.default'}

  req = urllib2.Request(url, headers=headers1, data=data)

  resp=urllib2.urlopen(req)

  ans=resp.read()

  ans=json.loads(ans)

  token=ans['access_token']

  full_token="Bearer "+token

  headers = {

    "Content-Type": "application/json",

    "Authorization": full_token

}

  payload = json.dumps(payload)

  response = requests.post(

    service_url,

    data=payload,

    headers=headers

)

  print response.text

  return response







if __name__ == '__main__':

    port = int(os.getenv('PORT', 5000))



    print "Starting app on port %d" % port



    app.run(debug=True, port=port, host='0.0.0.0')

I am getting the response as 200 once i post the response , but not getting the response in webchat.
This is the response i get in python code

{

  "id":"b5b52b9e464b4e958b1219dadedfffce|0000003"

}

What is wrong here ? No response at all

Got this reference for this implementation.
