What are the limits of telegram api?

Question

Telegram

Tell me plz.
The site says that the limits for sending messages: 30 messages per second.
Is it so? Something a little too generous.

Answer 1

When working with a single chat, avoid sending more than 1 message per second. Of course, small peaks are acceptable, but over time you will start getting a 429 error.
When sending notifications to multiple users, the API will not allow you to send more than 30 messages per second. To overcome this limit, you need to split the shipment into parts with a large interval between them (about 8-12 hours).
When working with a group, the limit is set to 20 messages per minute.
