Use Webhook Connector to send data from PowerShell to Microsoft Teams

Yesterday we announced Microsoft Teams, a new chat-based workspace in Office 365. Microsoft Teams is an entirely new experience that brings together people, conversations and content—along with the tools that teams need—so they can easily collaborate to achieve more.

Check this video or the step-by-step introduction video to learn more.

One of the cool features is the connectors you can use with Microsoft Teams. Office 365 Connectors are a great way to get useful information and content into Microsoft Teams. Any user can connect their team to services like Trello, GitHub, Bing News, Twitter, etc., and get notified of the team's activity in that service


Scroll through the Connectors and select the Incoming Webhook Connector




Give your Incoming Webhook Connector a name and upload an fitting icon and click create.



Copy the Incoming Webhook url to your clipboard, we will need that info in our PowerShell script.



PowerShell script

We now are going to call the Incoming Webhook from PowerShell.

 [sourcecode language='powershell'  padlinenumbers='true']

$webhook = '[webhookurl]'

$Body = @{
        'text'= 'Hello World! from PowerShell'

$params = @{
    Headers = @{'accept'='application/json'}
    Body = $Body | convertto-json
    Method = 'Post'
    URI = $webhook 

Invoke-RestMethod @params

If everything works ok, this will be the result.


Have fun using Microsoft Teams!
