Expose localhost RASA chatbot for Telegram Integration
This tutorial will show how you can expose your RASA chat bot to integrate it with Telegram.
You can simply initialize a new project.
$ rasa init --no-prompt
Search @BotFather on telegram. Use '/newbot' to create a Telegram bot. Follow instructions until you set your bot name & get your Token for accessing Telegram's HTTP API.

loclx domain reserve --subdomain mybot
The default port for RASA server is 5005.
loclx tunnel http --reserved-domain mybot.loclx.io --to :5005
If you want these ports to be exposed during boot, you can create a systemd unit file as explained here.
Edit your credential.yml file and add your access_token , verify (your bot name) & webhook_url (replace with your domain).
telegram:
access_token: "826487496:AAE1C_rllVgoQ47sOJ9faM26nL6oE1ZcQE4"
verify: "testxyzbot"
webhook_url: "https://mybot.loclx.io/webhooks/telegram/webhook"
Search for User 'testxyzbot' & start chatting.
We haven't added any stories or domains. This bot is simply running off the default init model. Check official rasa docs for more info.

This is how you can have a working Telegram bot powered by RASA NLU with LocalXpose do the connecting for you.
