Attaching files to a channel on Microsoft Teams - microsoft-teams

I'm trying to send files to a channel in Teams, but I've found examples of asking a bot for something (for example I write 1 and he send me an image), and the bot's able send images or files like attachments (I don't need adaptive cards or message cards if your idea is Incoming webhook).
I need to send with a schedule request attachment files to teams, is that possible? For example, if such is possible to send a set of image attachment every 1 hour.
Thanks

In case this is still not resolved.
Please take a look at Send and receive files through your bot doc to see how your bot can send/receive file attachments.
For bot to trigger message based on backend trigger, please take a look at Send
proactive messages.
Sample code for both of these scenarios can be found in Bot Framework sample code repo.

Can we send file as an attachment along with message in teams programmatically?

Can we send file as an attachment along with message in teams using webhooks or api?
Currently we can send only text message using webhooks and not attach files.
I want to mimic the action in the screenshot below:-
Attach file present in the system
There are ways to first upload file to one drive and then send its link in the teams message but I do not want to use that solution.
Is there a way to directly upload file from your system as an attachment to the microsoft teams using webhook or any alternative way.
Thanks!!
Currently it is not supported to send attachments using webhook. You will need to use bot to send and receive attachments. You can refer this link.

MS Teams Incoming Webhook issue

I've created an incoming Teams Webhook connector within a Teams group (using the method below).
I can successfully curl to the webhook internally and get the message to display ok.
MS have checked my tenant and access is as expected.
When I apply my URL for the webhook to any external service they eventually come back stating there was a problem detected with the webhook (Please make sure that your webhook endpoint of xxx is responding with a 2xx response code within 30 seconds of initial connection.)
Can anyone advise what else may need to be done?
Thanks
In Microsoft Teams, choose More options (⋯) next to the channel name and then choose Connectors.
Scroll through the list of Connectors to Incoming Webhook, and choose Add.
Enter a name for the webhook, upload an image to associate with data from the webhook, and choose Create.
Copy the webhook to the clipboard and save it. You'll need the webhook URL for sending information to Microsoft Teams.
Choose Done.
Incoming webhooks are special type of Connector in Teams that provide a simple way for an external app to share content in team channels and are often used as tracking and notification tools. Teams provides a unique URL to which you send a JSON payload with the message that you want to POST, typically in a card format. Cards are user-interface (UI) containers that contain content and actions related to a single topic and are a way to present message data in a consistent way. Please test the incoming webhook url using postman and let us know the payload result or status code. Would be help full for us to understand more.

Message sent by Microsoft Teams bot is not displayed in the conversation

I have tried to send MS Teams bot message request via rest api:
End point: https://smba.trafficmanager.net/ca/apis/v3/conversations/{conversation id}/activities
{"text":"test","type":"message"}
And got empty response:
{}
The message i sent did not appear in the conversation.
Any idea where i could have misconfigured?
It is possible that trustServiceUrl needs to be run before a message is sent, i can't find equivalent rest api to call.
You definitely do need call trustServiceUrl before sending the message. In addition, you need to have additional properties on your activity, like the destination user or tenant id. Please refer to the documents on this, and good starting places are here and here.

Sending a message to users as a bot in bot channel of Microsoft Teams using the Graph API

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.

Conversation in Microsoft Teams

We need to automate few notifications from our web application. These get triggered at various phases, for eg. Step A, B or C would trigger emails to specific parties.
AS an improvisation to this, teams integration is being looked at where a specific channel is being created and with webhook, the messages can be posted.
I created a custom channel with an incoming webhook and I posted a JSON request (of type #messagecard) which was viewable in the channel. But the need is to really establish a conversation and not separate individual messages. By conversation, we mean a scenario or tree structure like below
OverAll status 1 (Parent message)
--> subsequent reply (child message)
---> subsequent reply (child message)
I did some R&D and found that the incoming webhook post request does not return any message id (thsi feature doesnt exist)
What I do not understand is how bots (Azure or Microsoft) can help here.
Please advise
Webhooks/connectors is perfectly fine for the single messages, are you're seeing, but I don't think it will give you the ability to create and then continue an existing "conversation" (i.e. a thread). You certainly could achieve something like this using a "bot"-based approach. In practice, it's kind of "bot+extra" because you need two things:
1) A bot registered into the channel. This will give you some key info you need to be able to send messages from outside Teams - something called a "proactive" message. Having the bot in the channel also means you have something with the authorization to send a message to the channel
2) Next you need to implement the Proactive message. Have a look at my answer here to see more: Programmatically sending a message to a bot in Microsoft Teams (the answer is in C# - not sure what language/platform you're using, but the same concepts apply in Node)
In addition to the pro-active message, once you send that first message, you need to store the message reference that comes back from "SendToConversationAsync". You then apply it to the subsequent messages, as I've described in the answer here: How to add a mention in Teams alongside an adaptive card using Bot Framework
Hope that helps
