Simple Golang Chat-GPT (OpenAI) Telegram Bot

Step 1:

Create a telegram bot via https://t.me/BotFather and get it's api token

Step 2:

Register for an open ai account and grab the api token

Step 3:

create your .env file cp .env-example .env then complete it by inserting your tokens.

Step 4:

Telegram wants an SSL endpoint to deliver bot requests too your server.

You have some options here.

• Services like CloudFlare and its proxy option with Flexible ssl mode. (Recommended)
• Use letsencrypt service for free ssl (needs renew every 3 months)
• Self Signed ssl on your server and sending the certificate it via setWebhook api call. (needs code change)

We used CloudFlare.

And here is a simple nginx configuration for the subdomain pointing to the server. change 8000 to value of golangPort on .env file:

server {
    server_name yoursub.domain.com;
    listen 80;
    listen [::]:80;
    server_tokens off;
    location / {
        proxy_pass http://localhost:8000/webhook;
    }
}

Step 5:

run docker-compose up -d the bot is ready!
