telegramClient | Kotlin Multiplatform Telegram Client | Mobile library

There are 2 issues, to begin:

Okay, so I have actually confused terminology here. Telegram does not show the participant of the channel even on the official app (if you are not an admin), however, for Groups the get_participants method works great

I got it I just had to import asyncio and wrap the function like this:

I was able to fix the problem by using a boolean flag instead of using print in the for loop

You can refer the documentation for Contacts here. Basically, all you need to do is iterate over the users and access id for each user.

I would propose to take a look in the RateLimiter direction. Maybe it does not work as expected, depending on the number of requests your application does over time. From the Javadoc for Ratelimiter: "It is important to note that the number of permits requested never affects the throttling of the request itself ... but it affects the throttling of the next request. I.e., if an expensive task arrives at an idle RateLimiter, it will be granted immediately, but it is the next request that will experience extra throttling, thus paying for the cost of the expensive task." Also helpful might be this discussion: github or github

I could imaginge there is some throttling adding up or other effect in the RateLimiter, i would try to play around with it and make sure this thing really works the way you want. Alternatively, consider using Spring @Scheduled to read from your queue. You might want to spice it up using embedded JMS for further goodies (message persistence etc).

The error "UPDATE_APP_TO_LOGIN" happens because your Telegram Client/Library uses an obsolete API layer.

As stated on its project page, TLSharp is no longer maintained and will not be updated to fix this.

You should switch to WTelegramClient which is:

• offering up-to-date API (latest layer)
• safer (latest MTProto v2 implementation and many security checks)
• feature-complete (covers all API methods, handling of updates, multiple-DC connections)
• easy-to-use (API calls are direct methods with fully documented parameters in VS)
• designed for .NET 5.0+, but also available for .NET Standard 2.0 (.NET Framework 4.6.1+ & .NET Core 2.0+)

Available on Nuget. ReadMe/Github is here.

The problem is inside your main function. When you await for a coroutine to return it doesn't mean that the execution continues to the next expression. So, in your code the line await user2.pool() is going to be executed only when the user.poll() coroutines returns a value, this is when the session '321' is disconnected.

You need to run the tasks concurrently; you can use the function asyncio.gather. Reworking your main:

You cannot accelerate this process. The click method sends a request to Telegram, which then sends an update to the bot. The bot must answer the update to Telegram, which will then "forward" the result back to your original click.

In essence, click must wait for the bot to answer the query, and if it does not answer to it fast enough, it will be slow. The bot may need to be fixed to answer faster (or at all; if it doesn't answer, Telegram times out and click returns None).

What you can do is spawn a new asyncio task to run the click "in the background", however, it's not good practice, as one should always await all spawned tasks, and if the code depends on the bot's response, you will have to wait for it one way or another. I don't recommend this approach, but it technically "works".
