Teams Message Cards – Part I (Microsoft 365 Roadmap)

This is part I of a series where the goal is to both create a reusable template as well as be able to present useful information from the Microsoft 365 Roadmap in a Teams channel.

Tools used:

As the roadmap URL provides an RSS feed, I can use Powershell to:

  • Get data (I would like to do this once per day)
  • Parse the data, select the parts I want
  • Adapt the output as JSON in a supported Message Card format
  • Post it in the Teams channel by using an incoming webhook

Further, I would like the message cards to be color coded based on the status of the feature:

  • Red: In development
  • Yellow: Rolling out
  • Green: Launched

This resulted in a short script to show any updates from the roadmap in the last 24 hours.

Unverified sender available in Outlook clients


  • Set up an incoming webhook in your selected Teams channel
  • Copy the URI that the connector generated (you need that later)
  • Download the script from here
  • Adjust the user defined variables to fit your environment, as mentioned above
  • Do a dry-run to see if anything is posted. If not, try to adjust the $Hours variable to a higher value


The script is pretty basic. All that is needed, is to adjust the $URI and $Hours variables.

# User defined variables
$URI = 'Teams webhook URI'
$Roadmap = ''
$Hours = '24'
$Now = Get-Date 

Please note that $Now variable is needed to calculate the time, so don’t change that.

To request the data, it runs an Invoke-RestMethod with the variables defined.

# Request data
$messages = (Invoke-RestMethod -Uri $Roadmap -Headers $headerParams -Method Get)

The script then:

  • Goes through any new announced features and calculates if they happened within the defined timeframe (last 24 hours)
  • Further it does a count of the message.category values, as we need to separate the first value from the rest
  • In order to avoid a failed JSON payload, we need to convert the string to JSON before we build the payload
  • Then the script will color code each entry based on state of the roadmap item
# Parse data
ForEach ($msg in $messages){

        # Add updates posted last 24 hours                
        If (($Now - [datetime]$msg.pubDate).TotalHours -le $Hours) {
                # Count, join and prepare category for use in the card
                $categoryno = $msg.category.Count
                $category = $msg.category[1..$categoryno] -join ", "
                # Convert MessageText to JSON beforehand, if not the payload will fail.
                $Message = ConvertTo-Json $msg.description

                #Set the color line of the card according to the Status of the environment
                if ($msg.category[0] -eq "In development")
                    $color = "ff0000"
                            if ($msg.category[0] -eq "Rolling out")
                                    $color = "ffff00"
                                            $color = "00cc00"

Then we use our data to create a JSON payload. I choose to create it with a here-string, adding the values and setting the color.

The message card playground is a good place to validate your JSON payload.

# Generate payload(s)          
$Payload =  @"
    "@context": "",
    "@type": "MessageCard",
    "potentialAction": [
            "@type": "OpenUri",
            "name": "More info",
            "targets": [
                    "os": "default",
                    "uri": "$($msg.Link)"
    "sections": [
            "facts": [
                    "name": "Status:",
                    "value": "$($msg.category[0])"
                    "name": "Category:",
                    "value": "$($category)"
            "text": $($message)
    "summary": "$($msg.Title)",
    "themeColor": "$($color)",
    "title": "Feature ID: $($msg.guid.'#text') - $($msg.Title)"

Lastly, if there are any new updates, post them in the defined Teams channel:

# If any new posts, add to Teams
Invoke-RestMethod -uri $uri -Method Post -body $Payload -ContentType 'application/json; charset=utf-8'

  • When you’re happy, set the script to run on a schedule that aligns with your $Hours variable:
    • Being cloud-first, Azure automation is what I use

This script is the base for the next scripts.
