Telegram URL to send message to specific bot - url

Is it possible to craft a t.me URL that prompts the user to send a specific message to a specific bot. The closest I've found so far is t.me/share/url?url=my%20message, but that doesn't specify a username so the user has to choose one. I don't see the t.me URLs documented anywhere.
Note: this is not the same as sending a message via the API.

You can use deep linking to bot, use following format like this link:
https://t.me/username?start=<token>
Your backend will receive /start <token> . The user however will just see normal
/start
on their chat window.

User shown opted in but messages failing due to 'not opted in'

I want to send Whatsapp transactional messages to users and for which I am opting in them via Gupshup's WhatsApp API. This is the API that I am using:
When I go to Opt In users screen, I am able to find users who have opted in via this API. Refer below image for it:
The issue is when I try to send messages to these users (opt-in via Upload), messages failed citing the reason that user is not opted in. Refer below image for it:
Users who have opted-in via API seem to have two different status at the same time and I am not able to find out why. Do you know what may be causing this strange issue?
If you are using sandbox, the you have to send PROXY appname, through your whatsapp.
But once when your app is live, user do not need to send this message, and you will be able to use the workflow you defined above.
Hope it helps!

Slack api conversations.history returns error: not_in_channel

I'm starting out with the Slack API and trying to just get a list of messages.
Here are my steps:
Created a Slack app and gave it channels:read and channels:history scope (also re-installed it)
Queried the list of channels with conversations.list (this worked fine)
From the output of conversations.list, I found a channel that I use and copied the id
Used the conversations.history api with the channelid from step 3
Result:
{ "ok": false, "error": "not_in_channel" }
I'm not at all sure what is happening here. I definitely have messages in the channel, and the documentation page for that api does not say anything about this "not_in_channel" error code.
What am I doing wrong?
After a long time of investigations (~2 hours), I found an easy approach. For Caleb's answer, I didn't understand how to invite a Bot to the channel. Hence, I am posting this answer.
Go to your Slack Channel and type the following as a message.
/invite #BOT_NAME
Eg: If your Bot name is SRE Incident Manager the command would be as follows.
/invite #sre_incident_manager
As soon as you start typing #, Slack will automatically suggest. So it becomes easy. For this, the Bot needs to be added to your Slack Workspace.
PS: Original answer.
The error not_in_channel has the exact meaning, your custom Slack app should be added to the channel.
Exact solution 1
To resolve the error, in the Web Slack interface:
Open channel settings
Click on the Integrations tab
Click Add apps and find your custom app.
Slack app might have different interface, see Iryna Vernik's answer.
Alternative solution 2
Give access to the bot to all channels by adding workspace wide scope, for example, chat:write.public. Depends on your needs and security requirements.
Alternative solution 3
To access the channel chat from API specify Incoming webhook. Slack will generate a unique URL with the token per each channel. Only convenient for a few channels.
This error arises when you are using the bot oauth token and the bot is not invited to the channel. To solve this you need to
Invite the bot(slack app) to join the channel.
Use the OAuth Access Token instead
To add Bot to your channel you need to write /invite #Bot_name in the slack channel
I also didn't understand how to invite a Bot to the channel. Way that was proposed by Caleb and Keet was not clear for me or not working. From my side, 'invite' work after
open channel
in Details tab, choose a 'More'clause
in dropdown menu, chouse an 'add app'
in pop-up look for you app (bot)
Also i was use Bot User OAuth Access Token, because i need this functionality in private channel (additionaly, you should add for bot groups:history scope)
FOr me, instead of invite a user/bot, I invite the app.
I'm getting started with the Slack API as well, and I've come to realize that not_in_channel simply means that the user/bot you are using the token for hasn't joined that particular channel you're trying to perform an action on.
Think of it this way: if you're using Slack on the web-browser or web-app, you wouldn't be able to post a message on a channel you haven't either joined or was invited to.
☝️ You'll also never run into this issue through the Slack UI/UX because you're not even able to access the channels UNTIL you are invited or join it.

However, because we're using the API we can essentially skip some steps, and in this case we skipped the step where a user/bot has joined the channel before doing the action we're trying to perform (writing a message, grabbing information, etc).
💪 How to address this
There's probably plenty of ways to do it that I'm not versed in, but if you're just concerned about a specific channel or two without the concern of scaling to x channels I'll list the way that worked for me.
📇 /invite Slash Command
As others have mentioned, putting /invite in the message box lets you use Slack's slash command shortcut to add users. What's important is this way also allows us to invite bots to the channel.
Putting "#" triggers Slack to start auto-suggesting, which is why it then becomes easy to find your bot name in the list.

Hope this helps answer people's question on why it's happening, and thank you to the original posts that got me out of my initial mess. 🙏
As all others said, you need to join each channel.
The bot can join channel programmatically by using API below:
https://api.slack.com/methods/conversations.join
Don't forget to add permission of conversations.join

Upload file using slackbot as Direct message

I am created slack bot, is there is any possible way send reply message as file? (I need to sent some file as reply message based on input). I tried using api file.upload it make the file as private not able access using url, but if i am upload to channel using sampe api, file is public, is there any way to send direct message as file by bot)
Yes. You can share a file directly and privately with a user by sharing it in a direct message channel with the user.
Just put the {user-id} of the user you want to share the file with in the channels parameter of the files.upload API method and you are all set.
Your slack app will need the files:write:user scope. This also works with bots.
Example for user with ID U12345678:
curl -F content="Hello" -F channels=U12345678 -F token=xoxp-your-token-here https://slack.com/api/files.upload

Using the Slack web API when deep linking to direct message/IM, I get "#deleted-channel"

When responding to a slash command with a string that includes a channel ID like <#C3989289>, the response in Slack shows a deep link to that channel "#general.
When I do the same for a direct message or IM, the response in Slack shows "#deleted-channel" and it's not a link.
I don't see anything in the docs about why this: https://api.slack.com/docs/message-formatting#linking_to_channels_and_users
Slack has confirmed that their system is designed in this way to protect private channels/direct messages from being made aware to users, even if the recipient of the message containing the deep link does belong to that particular channel/DM.

Facebook OpenGraph API: Can I Silently Send a Request from One User to Another?

How do I send a facebook app requests from one mobile user to another using the Graph API?
I have looked at facebooks documentation but the only options I have found are to A) send an app to user message from the app (which I can't get working) or B) to use the request dialog, which doesn't seem to let me send a request to a single user.
FB has instructions for how to build a custom "Multi-Friend Selector" but apparently not for mobile.
I have tried using HTTP POSTing to
https://graph.facebook.com/%s?access_token= ...
with POST data set to
message='Test Message'
but I get
WWW-Authenticate: OAuth "Facebook Platform" "invalid_request" "(#2) Failed to create any app request"
I have also tried in the Graph API Explorer but I get the same thing.
I don't want to send these messages to users that have installed the app and I don't mind the user having to provide confirmation for the FBFrictionlessRecipientCache. Also, my app is in Sandbox mode, but I only need to send the requests to the other developers.
I am looking for anything that will let me do multi-friend selectors or ask for lives, or get help from a friend, like I see in several mobile games these days.
You can use presentRequestsDialogModallyWithSession from FBWebDialogs.
You must specify a "to" parameter to identify the recipient, and you must use the FBFrictionlessRecipientCache.
The "to" parameter identifies the recipient. It stops the select user dialog from appearing.
The first time you send the request to each recipient the user will have to grant permission. After that, the FBFrictionlessRecipientCache will allow the request to be sent relatively silently (a dialog pops up briefly and goes away by itself).
