Developers using the Telegram API must maintain and start displaying official sponsored posts correctly in their apps by January 1, 2022.
Using the Telegram API will continue to be free for all developers. The rules regarding monetization in third-party applications remain the same: developers are allowed to monetize their efforts through their own advertising or other legal means, provided that all monetization methods used in their applications are clearly mentioned in their app store descriptions.
If the rules are ignored, Telegram will disable applications that violate them.
Sponsored messages in third-party apps
Telegram continues to grow worldwide, in part thanks to third-party apps using the Telegram API. To cover the increasing costs that come with this growth, Telegram added sponsored messages – a paid privacy-friendly way to promote bots and channels.
Third-party developers using the Telegam API are required to support and properly display official sponsored messages in their apps by January 1, 2022. Unfortunately, Telegram cannot financially sustain third-party apps that do not display sponsored messages and they will have to be disconnected.
Telegram's API usage will continue to be free of charge for all developers. The rules regarding monetization in third-party apps remain the same: developers are allowed to monetize their coding efforts through advertising of their own or other legitimate means, provided that all the methods of monetization used in their apps are prominently mentioned in their app store descriptions.
