title: Send message notification to Microsoft Team through REST API
body: <p>I've read lots of docs on the Microsoft Web Site and here, but I couldn't find a solution for my case yet. 
  Basically what I need is to consume a Microsoft Rest API (Graph?) to send a message notification(To a specific user) from an external app, using preferably <strong>NodeJS</strong>, <strong>Java</strong> or <strong>Python</strong>. </p>
  
  <p>The closest I think I got was here:
  - <a href="https://docs.microsoft.com/en-us/graph/api/resources/chat?view=graph-rest-beta" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/graph/api/resources/chat?view=graph-rest-beta</a>
  - <a href="https://docs.microsoft.com/en-us/graph/api/resources/chatmessage?view=graph-rest-beta" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/graph/api/resources/chatmessage?view=graph-rest-beta</a></p>
  
  <p>I couldn't find the method send though. Also those docs are under beta version which there is a warning to not use it on production apps.</p>
  
  <p>On the link below (Which is under 1.0 version), I can see the resource <strong>chatMessage</strong>(Preview) and the Method <strong>send</strong>, but when I click on it I get 404:
  <a href="https://docs.microsoft.com/en-us/graph/api/resources/teams-api-overview?view=graph-rest-1.0" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/graph/api/resources/teams-api-overview?view=graph-rest-1.0</a></p>
  
  <p>My need is to send a one way communication (Not back and forth, no need of Bots), just a simple notification and that's it. </p>
  
  <p>Is it possible to implement such a solution? Any reference that could help? </p>
  
  <p>Thanks</p>
