Telegram Bot API

⭐ Beginner's Pick Social / API Key Intermediate HTTPS
Varies by plan (check documentation)

Overview

The Telegram Bot API lets you build automated bots that can send messages, images, and files through Telegram chats. You authenticate with a bot token from @BotFather, and all requests are simple HTTPS calls — no special libraries required. It is one of the friendliest APIs for beginners wanting to build their first messaging bot.

💡

Beginner Tip

Get your bot token by messaging @BotFather on Telegram with /newbot. Use the getUpdates endpoint first to see incoming messages before building more complex logic.

Common Errors & Troubleshooting

401 Unauthorized Bot token is invalid or missing the bot prefix format.
Regenerate your token via @BotFather and paste it exactly as provided, without extra spaces.
chat not found The chat_id used in sendMessage does not exist or the bot has not been added to that chat.
Send a message to your bot first, then call getUpdates to retrieve the correct chat_id.
Bad Request: message text is empty The text parameter was sent as an empty string.
Always validate that your message string is non-empty before calling sendMessage.
