Telegram, the popular messaging app, has introduced a Contact API that allows developers to interact with Telegram users programmatically. This article will delve into how you can use this API to retrieve contact information from Telegram users.

Telegram Contact API Overview

The Telegram Contact API enables applications to fetch detailed user information such as phone numbers, usernames, and more. It's particularly useful for integrating Telegram functionality into other platforms or services.

API Key and Authentication

To utilize the Telegram Contact API, you need an API key obtained from the Telegram BotFather. This key is essential for authenticating your requests to the API.

Example of Obtaining an API Key:

• Step 1: Go to https://t.me/BotFather
• Step 2: Start a conversation with the bot.
• Step 3: Use the provided instructions to obtain an API token.

Requesting Contact Information

Once you have your API key, you can make authenticated HTTP requests to the Telegram Contact API using various programming languages like Python, JavaScript, etc.

Example in Python (Using requests library):

import requests
from requests.auth import HTTPBasicAuth
# Replace 'your_api_key' with your actual API key
api_url = "https://api.telegram.org/botyour_api_key/contacts"
response = requests.get(api_url)
if response.status_code == 200:
    contacts = response.json()
    print(contacts)
else:
    print(f"Error: {response.status_code}")

Handling Responses and Error Messages

When making requests to the Telegram Contact API, it's crucial to handle responses appropriately. Here’s a brief guide on how to parse JSON responses:

Parsing JSON Response:

def parse_response(response_data):
    if isinstance(response_data, dict) and 'ok' in response_data and response_data['ok']:
        return response_data['result']
    else:
        raise Exception("Failed to get contacts")
contacts = parse_response(response)
print(contacts)

Conclusion

The Telegram Contact API provides a powerful tool for developers looking to integrate Telegram functionalities into their applications. By following these steps, you can effectively authenticate your requests and manage the contact data returned by the API.
