My goal is to make a Telegram Bot using Python that does the following:
The user types a command
The bot explains what the user should type next.
The user types certain information
I use that info to fetch a value in a python dictionary.
The bot replies with that info
I have already created the bot and set the command. The problem is that I don't know how to keep the bot "listening" . I have looked up in the docs but I have only found getUpdates, which gets the user's responses but only when you hit run.
res=requests.get(url=f"https://api.telegram.org/bot{bot_token}/getUpdates")
I would like to set a webhook, and I know there is a method for this but I'm not shure about how this works.
When you are a PHP programmer, setting the webhook through a URL and using setWebhook would do the trick and telegram will send the result to this link whenever a user sends an update to the bot. But, Python programmers have to use a different approach, I think. The main, and while, the easiest approach to make the bot listen permanently to the request is to python-telegram-bot module.
There are a few links that can help to build your first pythonic bot that can respond to users' updates.:
Python-Telegram-Bot Repository, which is the repository of the module.
A few examples of bots created using this module, can give you insight into the process of creating your first bot.

What I'm trying to understand is how Discord.py creates and sends responses from their on_message function.
Take this as an example:
#client.event()
async def on_message(message):
print(message.content)
I'm trying to understand how Discord.py retrieves new messages from Discord without refreshing the channel histories for every single channel in every single server to scan for new messages which would surely hit Discord's rate limit.
Is there a way to scan for new messages with Discord's API using fetch or post requests? I am not trying get a solution on how to scan new messages using an already made library. I want to achieve this using only the requests module in python.

Discord bots establish a websocket connection with Discord's servers, which is essentially a (secure) two-way tunnel. This means that once the connection is up, Discord can send events to you. Instead of you having to manually fetch every single channel, Discord tells you "Hey, a message was created", and the payload attached will give all the additional info about it.
The Discord (not discord.py) docs have detailed info about how everything works behind the scenes, to help the people creating the Bot libraries for you. For example, this section details which types of events Discord can send to you. To see how something is constructed, click on one of the event types and read up on the data that Discord provides.

Not really, unless you do in fact send a GET for every single channel, which will get you ratelimited. There's really no reason to ever use only GET/POST requests (other than Webhooks, where you just send a POST with your info to send a message to a channel without a bot).
If you'd like to read up on Discord's API, the docs I linked contain a full spec of everything, so you could try to do whatever your heart desires (... and the API supports).
I am building a telegram bot that will automatically add messages to preexisting menus in a bot ( created by Manybot, not with python ) once they are uploaded to a specific channel.
I spent a week or so trying to find a way to update preexisting menus but it can't manage to find a solution.
even when I try to run an infinite loop to monitor any messages to the bot ( using any telegram-python library out there ) i get this error :
Conflict: can't use getUpdates method while webhook is active; use deleteWebhook to delete the webhook first
and i am forced to delete the webhook , which will in turn disable every command i added to the menus and need to create another bot
I would really appreciate any help .
The problem is not related to existing webhooks, it's the fact that each bot token can poll / webhook only once.
In other words, you can't have two scripts running with the same bot token, regardless if it's long polling or a webhook.
This is a limitation of the Telegram Bot API.
You can only run your own script when the manybot version of your bot is paused, stopped, turned off, etc. The getUpdates method will reject new connections with the same bot token.
You can either use a second bot token to use other commands if your setup allows it, or use the MTProto API with frameworks such as Pyrogram or Telethon.
i'm developing a python telegram bot and i have a script that is always running (for receiving new command from telegram) and i want the bot to send messages when the user perform a action in a website.
example: the user start the bot, the bot send a link to perform an action in the website (like login to the user's account and connect the telegram id with the user id) and then send a confirmation message on telegram that all's good.
my problem is how i can tell the python script that the action in the browser is done? for now i'm constantly query a database but my solution is pretty dumb because if the user don't perform any action the query can go forever.
any suggestion how to do it correctly?
thx <3
I see two viable solutions here:
Send the message directly from the website. While only one process is allowed to fetch updates at a time, you can make other requests from as many servers as you like. Depending on how your website works, you can make a plain HTTP request to the Bot API or use an API wrapper like python-telegram-bot or a wrapper in a different language to make the request. e.g. if you're running a php-based website, you could use a php API wrapper.
If for some reason 1. is not an option for you, you can try to inform your running process about the user login. the PTB FAQ have an entry that should help you get started. If your website & bot are running on the same server, it might be possible to make the update_queue directly available to the website process. If not, you can try to set up a webhook for your bot and post an update to the webhook that you then enqueue into the update_queue
Approach 1. has the downside that you don't have all the bot logic in one place, but it should be by far easier to implement than 2.

I have 2 discord client instances a bot and a user account. I have already figured out how to copy messages from one channel to another channel, basically a on_message event. However, I want to know if there is a way I can use the user account to fetch the messages, I've tried fetching messages in different guilds but they didn't work because the bot was not in the server and the bot is fetching messages. I've tried using the user account instance to do it but it didn't really work.
The comments were there as a guide for myself because I'm not that familiar with Python it's fairly new to me. If anyone knows how I can use the user account to get or fetch the messages I'd appreciate the help...
PS: I know that some of the code isn't needed, I haven't removed anything that isn't needed. I wanted to actually finish the project before inspecting it.
I just wanted to know that I have tried this myself and it is not possible. Because from discord.py's Docs. Which you can find down below, does not allow users (user account) to transfer data to a bot since you would need to request from discord API which leads to user getting banned (Very quickly) theere are some work arrounds but I would suggest not doing so since self botting is against the TOS of discord

EDIT: Another thing is that discord API blocks users from fetching or getting anything using a user account with discord.py
I built a Slack bot and tried to make my bot interact with another bot in the a channel, but it seems not working.
For example, I want to use the voting function of Polly (a Slack bot).
Regular users like me send /polly "Which is better?" "Tacos" "Pizza" message and Polly will create a Slack poll in a channel. But when I made my bot send the same message in the same channel (I use python-slackclient and chat.postMessage method), the message just like a simple text, in other words, it didn't trigger Polly.
So, in a channel, how can a Slack bot interact with another bot and trigger some functions of it?
Did anybody ever do something like this?
update
https://github.com/ErikKalkoken/slackApiDoc/blob/master/chat.command.md
I tried this method but got another problem...
The error message is
{'error': 'missing_scope',
'needed': 'post',
'ok': False,
'provided': 'identify,bot:basic'}
The Oauth token requires "post" scope, but official documents show that "post" scope is deprecated. How do I make my token have "post" scope?
I have tried to make two bots interact and didn't find it to work. Slack somehow recognizes the source of the message and if the message is sent by a bot or an app, it fails to respond to it. I have even tried to post the message as a user through the slack API but did not get it to work.
However, Bots can use the chat.command method to invoke a slash command.
Unofficial documentation can be found here:
https://github.com/ErikKalkoken/slackApiDoc/blob/master/chat.command.md
You are correct that the undocumented chat.command requires the post scope to work, which is not available in the standard OAuth process (e.g. you can not choose it as scope on the Slack app config site.)
The only currently working solution that I know of it to use a legacy token.
