📸 Multimedia Support Perfectly supports two-way forwarding of text, images, videos, files, and other message formats without losing any details.

🛠️ Administrator Commands

Note

: The following commands are only effective within topics in the administrator group. Commands sent by users in private chats will be silently intercepted and will not disturb administrators.

Command Action Scenario
/close Force Close Chat
The bot will notify the user that the chat has ended and reject new messages.		 Ticket resolved; politely ending the consultation.
/open Reopen Chat
Resumes message forwarding for the user.		 Accidental closure, or the user needs to contact again.
/ban Ban User
The bot will completely ignore all messages from this user (no notification).		 Malicious spamming, ad bots.
/unban Unban User
Restores the user's normal communication permissions.		 Giving a second chance.
/trust Permanent Trust
The user will be permanently exempt from CAPTCHA verification (never expires).		 Acquaintances, VIP clients, long-term partners.
/reset Reset Verification
Forcibly clears the user's verification status; re-verification required next time.		 Testing verification flow, or suspected account compromise.
/info View Info
Displays the current user's UID, Topic ID, and profile link.		 Checking user details.

🚀 Deployment Tutorial

Prerequisites

  1. Telegram Bot: Apply for a bot from @BotFather and get the Token.
    • Important: Turn off Group Privacy in BotFather (/mybots > Settings > Group Privacy > Turn off).
  2. Administrator Group: Create a Telegram group and enable Topics.
    • Add the bot to the group and set it as an Administrator (grant "Manage Topics" permission).
    • Get the Group ID (usually starts with -100).

    Tip for getting SUPERGROUP_ID: In Telegram Desktop, right-click any message in the group and copy the message link. The link will contain a segment like -100xxxxxxxxxx or xxxxxxxxxx. If you only see numbers xxxxxxxxxx, add -100 in front to get the full SUPERGROUP_ID (same applies to private channels/groups).

Method 1: One-Click Deploy via GitHub (Recommended ★)

This is the simplest automated deployment method. Cloudflare will automatically redeploy your Worker when you update your GitHub repository.

  1. Fork this repository to your GitHub account.
  2. Log in to the Cloudflare Dashboard.
  3. Navigate to Workers & Pages -> Create Application.
  4. Click the Connect to Git tab.
  5. Authorize Cloudflare to access your GitHub and select the telegram_private_chatbot repository you just forked.
  6. Configure Deployment:
    • Project Name: telegram-private-chatbot (or any name).
    • Production Branch: Usually main or master.
    • Keep others as default and click Save and Deploy.
  7. ⚠️ Crucial Step: Bind Database & Variables
    • After deployment, go to the Settings -> Variables page of the Worker.
    • Bind KV Database (Required):
      • In the Cloudflare sidebar menu KV, create a new Namespace (e.g., named TOPIC_MAP).
      • Go back to the Worker's Variables page, scroll down to KV Namespace Bindings.
      • Click Add binding, set Variable name to TOPIC_MAP (must be uppercase), and select the Namespace you just created.
    • Add Environment Variables:
      • BOT_TOKEN: Your bot token.
      • SUPERGROUP_ID: Your group ID (e.g., -100123...).
  8. Final Step: After configuration, go to the Deployments tab at the top, find the latest deployment record, and click Retry deployment on the right to apply variables.

Method 2: Manual Deployment (Simple & Direct)

If you don't want to link GitHub, you can copy the code directly.

  1. Log in to Cloudflare Dashboard.
  2. Go to Workers & Pages -> Create Application -> Create Worker, start from Hello World.
  3. Name your Worker and click Deploy.
  4. Click Edit code, copy and paste all code from worker.js in this project, overwriting the original code.
  5. Click Deploy in the top right corner.
  6. Configure KV & Variables:
    • Go to Settings -> Variables.
    • Add KV Binding: Variable name TOPIC_MAP, bind to a KV database.
    • Add Environment Variables: BOT_TOKEN and SUPERGROUP_ID.
    • Click Save and Deploy.

Final Step: Activate Webhook (Crucial)

Regardless of the deployment method, you must manually tell Telegram your Worker address. Visit the following URL in your browser strictly in order:

Set New Webhook: [https://api.telegram.org/bot](https://api.telegram.org/bot)<YOUR_TOKEN>/setWebhook?url=<YOUR_WORKER_URL> Replace <YOUR_TOKEN> with your bot token, and <YOUR_WORKER_URL> with your Worker's full domain or custom domain (e.g., https://xxx.workers.dev).

If it returns {"ok":true, "result":true, "description":"Webhook was set"}, the deployment is successful!

❓ FAQ

Q: Why does clicking the verification button do nothing? A: Please check if the Webhook is set correctly. You must ensure Telegram is allowed to send callback_query events. Please perform the reset operation in the "Final Step" above.

Q: Why can't the bot create topics in the group? A: Please ensure: 1. Group ID is correct (starts with -100); 2. Topics are enabled in the group; 3. The bot is an administrator and has "Manage Topics" permission.

🔒 Security Note

Important

Please keep your Bot API Token and Secret Token safe, as this information is critical to the security of your service.

Warning

Do not change the configured Secret Token arbitrarily! After changing it, all registered bots will fail to work because they cannot match the original token. If you need to change it, all bots must be re-registered.

  • Choose a secure and memorable Secret Token during initial setup.
  • Avoid using simple or common prefixes.
  • Do not share sensitive information with others.
