In Slack, users are pinged when they are #-mentioned in a channel. Is it possible for a bot or app to receive an event when a user is tagged this way? It doesn't seem to be on the Event Types API.
The app_mention event is meant to handle just this scenario.
Any time a message references your app by its bot username (e.g. #myBot), your app will receive this event along with metadata like the user ID who wrote the message, the text of the message, timestamp, and channel ID.

I am looking to build a slack app which can auto-reply to a person whenever they mention me in a channel or DM me. However, i cannot find any method in the slack API for the same.
Is there any particular way i am missing or this cannot be done in Slack?
When you say 'mention me', if you mean the bot,
then you can subscribe to 'app_mention' event and take it from there.
https://api.slack.com/events/app_mention
If you mean - you as user and not the bot, then the bot needs to be part of the conversation to read the messages. This means that it will not work with the DMs.
For channels, you can invite the bot to the channel you want to monitor, and capture the 'message' event to parse the message and look for your id.

I have deployed my bot on teams channel.
I would like to send a welcome message to a new user even before user sends a message to the bot.
can we achieve this for teams channel?
If yes, which event can be used to get that user is accessing bot for the first time.
You can use the ConversationUpdate event ActivityTypes.ConversationUpdate // in c#
When a bot is installed, your bot receives a conversationUpdate event. You can then send a proactive message to the user. Could you please try sending a proactive message and let us know if you face any issues?
The conversationUpdate event with the membersAdded object in the payload is sent when either a bot is added to a team or a new user is added to a team where a bot has been added. It is always a good practice to send a welcome message introducing the bot to all the users. Ensure that your bot responds to the conversationUpdate message, with the teamsAddMembers eventType in the channelData object. Also, keep in mind that the memberAdded ID is the bot's App ID itself, because the same event is sent when a user is added to a team.
Hope this helps.
I want my bot to respond only if anyone mentions its name like #mybot.
How to achieve this?
For that you need to use the Events API and subscribe to the event app_metion.
That way your app will receive all message that directly mention your bot with #mybot.
Those messages will be sent as request from Slack to the endpoint provided for receiving events.
I would like to open new conversations with users using the Microsoft Bot Builder on the Skype for Business channel. The only information I have is the user id (sip:user#domain.com)
In all the examples I could find, it is needed to save the conversation id/address of a user in a previous conversation to send a new message to this user.
How to create a new conversation as a bot to a user knowing only his id?
Thanks
Like you stated the userId is required to send a message to the user. A new conversation can be created by the framework but ultimately, you can't do anything without the userId and to obtain this the user has to contact your bot first. This is only true for channels like Skype. Other channels like E-mail just use the email address as an id. Skype uses a GUID as the id for their users. This is done so bots can't randomly add themselves to any user on Skype. Source
This doesn't mean you have to necessarily wait for the user to start a conversation. Whenever a user adds a bot to their contact list an event is send to the bot. This is the ContactRelationUpdate event. It warns the bot that a user has added the bot and the bot can then respond accordingly. Once this event is thrown you can obtain the userId from the activity and do whatever you want with it. Source
I have successfully setup my slack bot app, have enabled events etc. I want to receive any direct messages that the members of my slack team send to my bot. For this, I have only enabled Bot Events and No Team Events like below
However, I do not get any event on my webhook on this setting.
If I enable message.im event under Team Events, then I start getting events. But then, I get every message that the user (who has installed the app) sends to any other user in the team.
How do I get only the messages that are sent to my bot user?
Update 1
Based on this SO question I created a private channel with the bot user. Even then, the messages in the private channel do not arrive in my webhook with the above event subscriptions.
Update 2
After reinstalling the app, it seems to be working fine. I have only used it for few minutes after the reinstall so far. I will keep posting here how it goes. It would still be interesting to know what went wrong where.
It is normal behavior that your script receives all messages (for every channel your bot is a member of), not only the messages sent directly to your bot. At this time you can not filter further in the event configuration. So you need to filter out any unwanted message in your script handling the event.
