Nifi Integration with Microsoft Teams Channel

[#1]

Hello,

I've been stuck on this issue for weeks and am currently on a wit's end.

For the past few weeks, I've been trying to get my Apache Nifi to be able to post messages to a MsTeams channel. I've set up a MsTeams webhook and tried to use the 'InvokeHTTP' Processor to initiate a POST request to the MsTeams webhook.

I've also tried using 'ExecuteStreamCommand' processor to invoke a curl Command to send a message to my Webhook URL, but its not working.

This is what's inside my curl_command.sh,

curl -H "Content-Type: application/json" \ -d "{\"text\": \"Hello World from curl\"}" \ <Webhook URL>

Any help would be greatly appreciated

@eykf,

I never tried to send messages from NiFi to MS Teams but upon reading the documentation, I am not quite sure you need a Webhook URL at all.

MS Teams provides the Graph API to be able to integrate MS Teams into external application:

Now, assuming that you have the channel and the users already created, my first guess is that you would need only to send the message so basically all you have to do is create the API POST as described in the following link:
https://learn.microsoft.com/en-us/graph/api/chatmessage-post?view=graph-rest-1.0&tabs=http

And here are the parameters in case you need a more complex message, than the one described in the above link:
