Let's think of the following example:
1) I have a certain bot deployed on Azure
2) Bot can be talked via Facebook Messenger and via Skype
3) A certain user talks to the bot via Facebook Messenger and then he leaves.
4)A couple of minutes ago the same user resumes the conversation with the bot, but via Skype.
Is this possible? I assume Bot Framework doesn't have anything included for this, hence, that this isn't posible (as conversations are independent and state changes depending on the channel). Is there any way to identify a user (via some authentication method maybe), and then making this logic again?
Do any of you know any workaround for this?
Thanks in advance!
The Bot Framework Connector service is a component which provides a single API for your bot to communicate across multiple client services such as Skype, Email, Slack. Every bot and user has an account within each channel.
The channel account contains an identifier (id) and other informative bot non-structural data, like an optional name.
And there us unique conversation ID created for each conversation of each user for each channel. And you can customize your channel capabilities as described here.

I have created a teams bot and had a service written in .NET core to handle events and user's messages to reply accordingly.
When I install a bot in a group, I need to send personal message(one-to-one i.e between bot and the user) to all the members of that group on installation. I am trying to do that in OnConversationUpdateActivityAsync event handler (which gets fired when I install the bot). But in this event I am getting information of the user who is installing the bot, not the other members which are added in that group, also I am not getting any information of the channel(channelId and members etc.) in which the bot is getting installed.
Any different approach or solution will work.
Thanks in Advance.
You haven't said if you want the bot to message the users privately (like 1-1 between the bot and user) or just send each person a personal message inside the group chat, but in both cases, Proactive Messaging is your correct approach. If you want to send a message inside the group chat itself, see this sample.
If you want to send the users messages directly, 1-1, they need to have the bot installed as a personal app already. It's possible to do this automatically, but it's a bit more work, and requires Microsoft Graph. The proactive messaging is a bit different too - you get the list of members as per the previous sample, but see here for how to get the required 1-1 conversation details, and how to send the actual message. This last link also has documentation on how to get started, and some background reading (at the bottom of the page).
#Hilton is correct, You need to specify in which scope you want to notify user 1:1 or directly in Group chat?
App should be installed in user scope if notifying user on installation, You can proactively install the App in User/Group Chat/ team scope using Graph API. To notify users in Teams or Group chat, You can fetch the list of members using List conversation members API, When you install the App using Graph API Bot received converstionUpdate, You can save the conversationReference and use it for proactively notifying.
I would like to implement the following Scenario:
Within a Meeting that should take place in the real world in a room (not necessarily within MS Teams), I want a Microsoft Azure Chat bot to post a message to the meeting-chat, without someone having to add the bot to that meeting chat.
I noticed, that real proactive messaging to MS Teams is still not possible, a workaround is necessary: Catching a conversation reference including the users teams-chat-id while he adds the bot e.g. via personal teams app. This works good, if the teams app is pushed to all users within an organization via policies.
This workaround however is not possible within a meeting-chat, that might not exist at the time the bot should write to it. So, no possibility to catch a conversation reference to post to.
Also, I noticed that there does not even exist a MS Graph endpoint neither a connector within Logic apps to post a teams message to several users without cannel-context.
Do you see any workaround for this scenario, or is it simply not supported?
To my knowledge, you're right on both accounts - a bot can't proactively message a chat that it's not part of, and I don't think Graph supports messaging to group chats altogether, which is your scenario.
Just on a point of correctness though, a bot can proactively message (a) individual users (1-1), (b) group chats, and (c) Team channels, each separately (i.e. it does not need to be installed by each user, and message each user privately, unless that is the desired scenario. All that's required for each of these is the relevant "conversationid" that represents the specific conversation, and the ServiceUrl.
I have created a bot by following the steps mentioned in the doc.I have authenticated user using oauth 2.0 (auth code grant) as mentioned in the doc and in reverse I got a access token. But when I send message to channel in the teams using (/teams/{id}/channels/{id}/messages) API the message was sent on behalf of me. But I want my bot as the sender of message. Here is the image of the message that I have sent using the above API. and is there any way to send direct message to user as a bot?
Instead of using the Graph, there's another approach using the Bot Framework itself, to send a message to a team channel, a group chat, or a 1-1 conversation. The code doesn't even need to live inside the bot itself, it just needs to leverage the bot framework under the covers (for example, I have several Azure Functions that pro-actively message users). This idea is called "Proactive messaging" and you can read more about it in the docs here.
You do need to get certain fields when the user first installs the bot though, or any time the bot receives a message. I've described that more at Programmatically sending a message to a bot in Microsoft Teams. You haven't said what language you're using, but there are examples for a bunch of them - I can send you links if you let me know what you're using.
I developed a welcome bot using the Microsoft Bot Framework. I want to add it to Teams. In teams I want the bot to send welcome messages to only certain members belonging to a particular team or group. Please provide me advice or steps how to do it.
You can only send a welcome message to a specific user if that user first contacted your bot. This is done purposefully to minimize the possibility of spam bots being created. Once a user has contacted your bot you can capture the user's Id and, coupled with the conversationId, you can send future (proactive) messages.
We are building a bot which would require each of our customers to have their own SMS channel (unique phone number for them). From everything we can tell with the documentation of the bot framework is there is no way to do that. We want each of our customers to be able to add the bot to their own SMS number through twilio. Is this possible?

Yes you're right.

No, actually it's not possible :)
Shortly, BotFramework consist of three parts :
your bot logic which is a Web API service that exposes an endpoint
the channels (Skype, Facebook messenger, SMS etc)
the bot connector, where you create your bot by specifing the endpoint and one or multiple diiferent channels that the bot can use for conversations.
Because each channel can be associate only one time per endpoint hence per bot then you can't do multitenancy through the bot connector.
One solution is to create the multitenancy through the Web API service side by creating an endpoint for each customer. Maintenanbility will be difficult because of multiple endpoints you'll end up with the same number of bots into the bot director to manage. Each bot wil be associate to your customer number.
Updates: (I didn't test it but I'm pretty sure it can work)
Another solution is to use DirectLine channel and its Rest API that it exposes. If you opt for this solution it means that you will need to do a lot of things to make that work correctly after creating Direct Line channel:
you must create a client application to communicate with Direct Line channel through its REST API.
each customer can have their own number that you manage through Twilio
each message that a customer send using their SMS number and received via Twilio should trigger a call to the service of your client application
your client application will start a new conversation with Direct Line channel when a SMS is received.
each conversation started by your client application must take care about the SMS number who started the conversation by saving the state. Bot data per conversation and per user can help a lot.
when you receive a reply from the Direct Line Channel, your client application read the SMS number stored into the bot data and use this number to answer to the associated customer.
Hope it helps.
You can definitely do this.
You implement ICredentialProvider which is responsible for looking up appPassword by AppId and validating that the password is correct. This means you can have a database of bot AppId/Passwords that one endpoint services, and you look up the appid/secret and validate calls.
[ BotAuthentication(CredentialProviderType=typeof(SimpleCredentialProvider))]
Here is a simple sample implementation
