How to restrict a user using the Telegram Bot API?

Hello! Today we want to discuss one of the fascinating capabilities of the Telegram Bot API. We all know that Telegram is a very popular messaging platform, and bots are powerful tools for managing groups and channels. One of the key features of bots is the ability to restrict members of a group or channel. This can be done for various reasons, such as preventing inappropriate behavior. Therefore, by using the restrictChatMember method, we can execute this action.

Before starting, it's important to understand that to use this API, you need to have a unique token that you receive from the BotFather. This token allows you to communicate with your bot and send various commands. One of the commands we will be focused on is the restrictChatMember. This method allows you to restrict access for a specific user within a chat group.

To use this method, you must have a valid group ID and user ID. In addition, you can set different configurations, such as can_send_messages or can_send_media_messages, to specify what restrictions the user should have. Adjusting these parameters can help you control the behavior of group members better.

Now, let’s take a look at a simple code example that shows how you can utilize this method. In this code, we first need to specify the token and then send a request to the API. Ensure that the appropriate library is used for sending HTTP requests.

const axios = require('axios');
const token = 'YOUR_BOT_TOKEN';

async function restrictMember(chatId, userId) {
  const url = `https://api.telegram.org/bot${token}/restrictChatMember`;
  const data = {
    chat_id: chatId,
    user_id: userId,
    permissions: {
      can_send_messages: false,
      can_send_media_messages: false
    }
  };

  try {
    const response = await axios.post(url, data);
    console.log(response.data);
  } catch (error) {
    console.error(error);
  }
}

// Use the function
restrictMember('CHAT_ID', 'USER_ID');

Description

In the first line, we import the axios library for making HTTP requests.

In the second line, we store the bot's token.

In the restrictMember function, we begin by specifying the URL for the restrictChatMember method.

Then, we create a data object that includes chat_id, user_id, and permissions.

Within permissions, we specify what access the restricted user will not have.

Finally, by using axios.post, we send the HTTP request and can view the result in the console.
