Telegram Sponsored Messages

Getting sponsored messages 

 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.

Displaying sponsored messages 

Sponsored messages must be displayed below all other posts in the channel, after the user scrolls futher down, past the last message. The promoted channel or bot specified in the from_id field must be displayed as the author of the message. The message should also contain one of the following buttons at the bottom:

• View Bot — if a bot is being promoted. Tapping the button must open the chat with the bot. If start_param is specified, the app must use the deep linking mechanism to open the bot.
• View Channel — if a channel is being promoted. Tapping the button must open the channel.
• View Post — if a channel is being promoted and channel_post is specified. Tapping the button must open the particular channel post.
