The "Typing" action (sendChatAction) in Telegram
The "Typing" action (sendChatAction) in Telegram is a method of indicating bot activity that displays the status "typing..." in the user interface. This is a key UX element that signals the performance of long-term operations (content generation, data search). Unlike text messages, typing does not transmit content, but it prevents request timeout and increases trust in the bot.
What are the limitations of "Typing..." in Telegram?
1. Duration:
- The status is active for a maximum of 5 seconds.
- For operations >5 seconds → resend the action.
2. Intervals:
- Minimum interval between requests: 1 second.
3. Compatibility:
