My Telegram bot obeys rate limits (1 msg/sec, <20 msgs/min), yet receives error 429 when users click rapidly. Here’s revised sample code:
import time
def send_notification(chat_id, message):
print(f"Sending to {chat_id}: {message}")
time.sleep(1)
if __name__ == '__main__':
send_notification('chat001', 'Hello there!')
Based on my experience managing Telegram bots, I encountered a similar challenge. The built-in rate limits of Telegram can be tricky because even if you introduce a pause between messages, rapid user actions might still trigger multiple concurrent messages. In my case, I found that implementing a queueing mechanism rather than a simple sleep function helped prevent overlap. The issue often arises because the delay affects only one thread of execution. I overcame this by managing messages via a centralized message dispatcher that regulates message output so that even rapid user clicks do not overwhelm the API.
In my experience, the problem is likely due to concurrent messages being initiated by rapid user actions. I noticed that using a simple sleep call in a sequential manner isn’t enough if multiple threads trigger the send function simultaneously. To deal with this, I developed an asynchronous dispatcher that queues messages and ensures only one message is processed at a time. This approach not only adheres to rate limits but also provides a buffer for handling bursts in user activity. Proper synchronization between threads or processes is essential when implementing this solution.
hey, i had a simlar issue! try using an async lock to serialize msg sends. sleep alone isnt enough if multiple threads fire at once, leading to concurrent calls. give that a shot, might help prevent those 429s.
