This is proof-of-concept chatbot-based competitor to Intercom and Zendesk :)

Demo: users contact support via Telegram bot

• your clients chat with Telegram bot
• chats of each client are managed by your support team in Slack threads
• welcome messages
• !close command to close the thread, new messages from user will go to new thread

• integrations: Viber, Whatsapp, Discord, FB messenger, email, site contact form :)
• (maybe) move support system chats management from Slack to Discord (why not? it has threads too) or even custom portal (???)
• support emojis, image attachments, etc.
• internal messages visible for Slack team but invisible for bot user
• some AI integration and automations and anything else support systems may have

• install node.js and wrangler (NOTE: tested with Wrangler v1)
• create Slack app with enough rights to post messages at https://api.slack.com/apps?new_app=1
  • channels:read
  • channels:history
  • chat:write
  • chat:write.customize
  • groups:read
  • groups:write
  • groups:history
• create new Telegram app with https://t.me/BotFather
• use wrangler.toml.example to setup wrangler.toml
• call wrangler publish to deploy worker to Cloudflare
• use curl "https://YOUR_DOMAIN/telegram-bot?INSTALLBOT" --data "{}" to make Telegram send JSON notifications to your worker
• create private channel in Slack and add your bot there as integration
• go to https://api.slack.com/apps/YOUR_APP_ID/event-subscriptions to configure subscriptions to URL https://YOUR_DOMAIN/slack-bot and subscribe to events:
  • message.channels
  • message.groups
• ... DONE! :)

• open chat with your Telegram bot and press "Start" button
• new slack thread should appear in your channel, you can chat with your telegram user from there
• in case of any issues see logs with wrangler tail -f pretty
