Telegram bot webhooks are a way for your bot to receive updates from Telegram’s servers. When a user interacts with your bot, Telegram sends a request to your server, which is then processed by your bot. This process is called a webhook. Webhooks allow your bot to respond to user input in real-time, making the conversation more engaging and interactive.

# Check if the request was successful
if response.status_code == 200:
print('Webhook set successfully!')
