Generating a webhook out of assyst

We are early on in our journey in this area too  but have had some success triggering PowerShell based scripts from the Action Processor. Using Invoke-RestMethod and Invoke-WebRequest to trigger an Azure Hybrid worker runbook for some basic operational tasks.

Edit - also dawned on me that we have some MS Teams webhooks receiving monitoring notifications.

 

Function Invoke-TeamsAlert {

    [CmdletBinding()]

    Param(

        [Parameter(Mandatory = $true)][String]$Uri,

        [Parameter(Mandatory = $true)][String]$Title,

        [Parameter(Mandatory = $true)][String]$Text

    )

   Process {

        [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

        $JSONBody = [PSCustomObject][Ordered]@{

            "@type"      = "MessageCard"

            "@context"   = "http://schema.org/extensions"

            "summary"    = "$Title"

            "themeColor" = 'FF0000'

            "title"      = "$Title"

            "text"       = "$Text"

        }

        $TeamMessageBody = ConvertTo-Json $JSONBody -Depth 100

        $Params = @{

            "URI" = $Uri

            "Method" =  'POST'

            "ContentType" = 'application/json'

            "Body" = $TeamMessageBody

        }

        Invoke-RestMethod @Params

    }

}
