This specific error often arises when attempting to use a user's username instead of their unique chat ID, especially when sending messages from a bot. In this guide, we will break down the cause of this issue and provide you with a step-by-step solution to ensure your Telegram bot communicates seamlessly—whether you are using a chat ID or a username. The Problem: What Went Wrong? You attempted to send a message using both a chat ID and a username, but only the chat ID worked.

Username: Returned an error: {'ok': False, 'error_code': 400, 'description': 'Bad Request: chat not found'} The Root Cause of the Issue The error is due to how the Telegram API interprets the recipient information. Here’s the key takeaway: Unique Identifiers vs. Usernames Chat ID: This is a unique identifier for the target chat. It can refer to any type of chat including private chats, group chats, and channels. Username: This is formatted as @ username and can only be used for public channels and groups, not for private chats. What This Means for You Given this structure, attempting to send messages to private chats using usernames instead of chat IDs will always result in the Bad Request: chat not found error. Solution: How to Successfully Send Messages To resolve this issue and successfully send messages to users or groups, follow these steps: 1. Use Chat IDs for Private Conversations For all personal chats or private groups, always use the numerical chat ID instead of the username. 2. Use Usernames for Public Channels or Groups If targeting a public channel or a group that is visible to the public, you can use the username format (@ yourusername). Example of Correct Usage Here’s a simple guideline on when to use each format: For Private Chats: [[See Video to Reveal this Text or Code Snippet]] For Public Channels/Groups: [[See Video to Reveal this Text or Code Snippet]] Conclusion By understanding the distinction between chat IDs and usernames within the Telegram API, you can avoid errors and ensure efficient message delivery through your bot. Remember to use chat IDs for private messages and reserve usernames for public communication channels. With these adjustments in mind, you can confidently work with the Telegram API without encountering the 400 Bad Request error in your message delivery efforts. Happy coding!
