Telegram groups, supergroups, and channels - whatsapp

I'm new to Telegram. I need a clarification about one of the features of Telegram.
After creating groups or channels in Telegram, is there a way to know which recipients have received the message, and which recipients have actually read the message?
I know this functionality is available in Whatsapp, I was wondering whether Telegram also provide this functionality.

No telegram doesn't have that functionality yet. The moment you send a message to either a group, supergroup or channel, it is perceived as sent and read, however channels show you the actual number of people who have read the message.
You can however see the most active users by time spent on a supergroup using a third-party bot like ComStatbot.
Normal groups on telegram are the equivalent to Whats App groups. I recommend you to always convert to supergroup due to more functions.

Is there any way to transfer Telegram file IDs between different bots?

Many different media types on Telegram have a file_id and file_unique_id property, such as Stickers, Audio, and Document.
The file_id property is unique to each Telegram bot, so one Telegram bot will not report the same file_id as another Telegram bot will, even if it's the same piece of media.
I want to have two Telegram bots communicate with each other, but they are currently unable to do so because the file_id property is meaningless when one bot tries to talk to the other.
The file_unique_id property is consistent between the bots, but it does not seem like you can do much of anything with that identifier.
Is there any way to pass a reference to a file stored on Telegram's servers from one bot to another, without having to re-upload the file on both bots?
Bot can't interact with each other. But there's a workaround,
we can use channels as a medium (with only BotAPI)
Steps,
Add two bots as admin in channel
Broadcast the messages from Bot A to channel
Now, the Bot B will get these as channel posts and your new fileid
for the same file which will be unique for Bot B (obviously)
You have officially transferred all fileid to Bot B
There aren't any official methods to share fileIds between bots. In fact, you can't even get 2 bots talk to each other, also you won't get bot updates in groups. So bot to bot communication is not possible at all at this moment.
But what you can do is to use Mtproto api and sign-in to telegram as a normal user (with phone number). And follow these steps using the logged in account:
Start both of your bots.
Forward messages you receive from bot 1 to bot 2.
This way you'll be able to access any files in bot 1 in bot 2.
You can use Telethon to write a script that does the job for you, listening to updates coming from bot 1 & forwarding them to bot 2.
Also using normal bot api you should forward received messages to your logged-in account.
The only way is to use a shared channel. Both bots have admin access. However, you may encounter error 429 while transferring the file.
The solution is to send the files to the channel at longer intervals.

Telegram bots - how can we detect that a user has started typing?

We can get Telegram messages when they are complete and sent via long polling or webhooks, but is there a way to understand when the user has started typing?
I guess this is not a normal case for bots and I dont think there is a straight away method but could we fall back on the Telegram API for messaging apps for that?
Well, actually I found a solution in the current Bot API; inline queries. While they are not intended for this, inline queries send what the user types in to the bot in real-time, so you are alerted as soon as the first characters are typed in.
There is a way in Telegram Core API, named: updateUserTyping.
But there is not any way in Telegram Bot API yet (until today: 2016-10-17).
If you type or send a file to the bot during these processes you do not get any message from Telegram in your webhook, but it's possible they'll add a new feature to detect user typing in future Bot API updates.

Is it possible to build a telegram bot that aggregates posts of multi telegram channel?

Requirments:
1- Have a feed of posts that aggregate all posts of multi channels
2- have actions (bot command) on each post
3- When post of channel edited, correspondent post in the telegram bot edited too.
(If it is not possible, I want to know is it possible to edit a message that was sent to multiple recipients in one action or i have to change each of them by message id, chat id)
You can assume you are owner of all these channels and you set your bot as admin of all of them
Only creator/admins can add bots to channels and only as admins.
Bots (for now) can't read messages in channels.
Bots (for now) can't view any counters in channels.
So no such bot for now :(

Send message to th all of bots users (telegram api)

how to send Send message to the all of bots users?
There is no way to sned message to all ?
what is the method name ?
From Official API FAQ:
How can I message all of my bot's subscribers at once?
Unfortunately, at this moment we don't have methods for sending bulk messages, e.g. notifications. We may add something along these lines in the future. (...)
Obviously, if you store users chat_id, you can send individual message to all users (I use this method).
Navid wants to send message to all subscribers via bot.
If subscribers are more than 100 persons bot will very slow to sending all messages and may doesn't send messages to all.
Navid's question was how we can send message without this problem?
you can send with curl_multi_exec
Currently, a developer would need to implement a special broadcasting function that would send the message to each active user at the time adding a small delay to avoid hitting the rate limit of 30 messages per second (see https://core.telegram.org/bots/faq#how-can-i-message-all-of-my-bot-39s-subscribers-at-once). This would mean that a very popular bot with say 10K active users cannot give timely notification as the last user would get the message about 5 minutes after the first user.
Here is a feature request to ask to add a method in the Bot API to broadcast a message to all its active users at once. You can upvote this feature request. https://bugs.telegram.org/c/8463

Twitter: Unread direct messages using the Twitter API

Twitter:
I must be blind, but how would I find out how many unread direct messages a certain user has?
I'm using this documentation: https://dev.twitter.com/docs
Unread is a vaguely defined term. Unread is usually used in a specific client application. So, for instance, if you are using Twitterrific in two different machines with the same user account, both client instances will have different unread messages with respect to each other.
If you want to keep track of unread messages for your client, you must store the last message read ID. Each Twitter status is uniquely identified by a long number representing a global message ID, so it should not be difficult to accomplish.
Currently, Twitter doesn't offer this functionality. There is no way, currently, for Twitter to store which direct messages(or mentions or statuses for that matter) a user has read or hasn't read.
Though I believe they are looking into it.
