Each time the user opens a channel,
channels.getSponsoredMessages must be called to receive sponsored messages available for this channel. The result must be cached for 5 minutes.
Sponsored messages must be displayed below all other posts in the channel, after the user scrolls further down, past the last message. The promoted channel or bot specified in the
chat_invite mutually exclusive fields must be displayed as the author of the message. The message should also contain one of the following buttons at the bottom:
start_paramis specified, the app must use the deep linking mechanism to open the bot.
from_idor by importing the
chat_invite_hashinvitation link hash ».
channel_postis specified. Tapping the button must open the particular channel post.
The message should be marked as "Recommended" instead of "Sponsored" if the
recommended flag is set.
show_peer_photo flag is set, a profile photo bubble should be displayed for this message, like for messages sent in groups. The photo shown in the bubble is obtained either from the peer contained in
from_id, or from
additional_info flags are set, an additional "Sponsor info" menu item must be present in the message context menu (the menu that pops up when clicking on a button), that when clicked, displays the contents of the flags.
Once the entire text is shown on the screen (excluding the button),
channels.viewSponsoredMessage must be called with the
random_id of this sponsored message.
For the channel https://t.me/SecretAdTestChannel the system will always return a sponsored message: promoting either a channel, a particular message in a channel, or a bot with a start parameter.
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.
If their app allows its users to access content from Telegram channels, third-party developers using the Telegram 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.
