I am confused with all the rest API’s provided by Rasa.

I have trained my model successfully.

Now i want to do the conversation using .net code.

/conversations/<conversation_id>/messages

I am able to post payload to above Rest API but not getting bot output in response.

How do i keep getting responses of my input from API like it works with rasa shell?

To talk to the bot via REST use POST on

<base_url>/webhooks/rest/webhook

The body is a json containing sender and message

{"sender": <sender_id>, "message": <message>}

You can choose any string as the sender id.

I second that this is not well documented.

Hi @aniket, welcome to the community.

You can use rest channel to get response from the bot.

Also I have designed the chatbot widget for the same, it’s in jQuery but you can relate it:

Hope it helps

@JiteshGaikwad i am using GitHub - JiteshGaikwad/Chatbot-Widget: ChatBot widget easy to connect to RASA bot through REST channel for ui of my rasa chat bot i have used the following code in my connect.py

from rasa_core.channels import SocketIOInput
from rasa_core.agent import Agent
from rasa_core.interpreter import RegexInterpreter
from rasa_core.interpreter import RasaNLUInterpreter
from rasa_core.utils import EndpointConfig
from rasa_core.policies import KerasPolicy, MemoizationPolicy

# load your trained agent
interpreter = RasaNLUInterpreter('rasa/models/nlu/profiler/nlu')
agent = Agent.load('rasa/models/dialogue',

interpreter=interpreter,

action_endpoint=EndpointConfig('http://localhost:5055/webhook')
#for action endpoint
)

input_channel = SocketIOInput(
# event name for messages sent from the user
user_message_evt="user_uttered",
# event name for messages sent from the bot
bot_message_evt="bot_uttered",
# socket.io namespace to use for the messages
namespace=None
)

# set serve_forever=True if you want to keep the server running
s = agent.handle_channels([input_channel], 5500, serve_forever=True)

also i have use this in my credentials.yml

rest:
  socketio:
    user_message_evt: user_uttered
    bot_message_evt: bot_uttered
    session_persistence: true
rasa:
  url: http://localhost:5055/webhook

hey @vjaiswal693, the widget which I have designed is based on rest not socket.io you don’t need to use socket.io for that, it’s pretty simple just follow the below steps and you will get it up & running:

• In your credentials.yml, just add the below lines:

rest:
  # you don't need to provide anything here - this channel doesn't
  # require any credentials

• start your rasa server using the below command:

rasa run -m models --enable-api --cors "*" --debug

Hi @JiteshGaikwad, using you solution together with the rasa x is causing malfunction in the events.db and rasa x is stopping from store the conversations

Hello, I have deployed the rasa x in AWS server following this tutorial. Now, I am trying to connect to the rasa x using the Chatbot Widget but, it’s throwing an error.

post by n-k-chilagani on May 14, 2020

I still don’t know solution for this issue but, It got fixed after updating the rasa x version

Jitesh, your Widget is awesome, however I am having issues when deploying:

index.html is served by IIS on port 8080 rasa server is running on port 5005 rasa actions is running on port 5050

when I start the conversation I get blocked by CORS, because of the different ports: Front-End and Rasa backends.
