Microsoft Teams Send As Workflow

Send messages and Adaptive Cards to Microsoft Teams channels via Incoming Webhook.

• 📨 Simple text messages - Quick notifications and alerts
• 🎴 Adaptive Cards - Rich formatted cards with facts, images, and buttons
• 🔧 Raw payloads - Full control over custom message structures
• ⚠️ Helpful error handling - Clear guidance for setup issues

You need a Webhook URL from Teams. To create one:

1. In Teams, go to the target channel
2. Open Workflows app (search from Apps or click three dots below input)
3. Find template: "Post to a channel when a webhook request is received"
4. Name the workflow (e.g., "CLI Notification Bot")
5. Select target Team and Channel
6. Copy the generated HTTP POST URL

python3 scripts/send_teams.py <WEBHOOK_URL> --text "Hello Teams!"

python3 scripts/send_teams.py <WEBHOOK_URL> -t "🚀 Deployment completed successfully"

Inline JSON:

python3 scripts/send_teams.py <WEBHOOK_URL> -c '{
  "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
  "type": "AdaptiveCard",
  "version": "1.4",
  "body": [
    {
      "type": "TextBlock",
      "text": "Build Report",
      "weight": "Bolder",
      "size": "Medium"
    }
  ]
}'

From JSON file:

python3 scripts/send_teams.py <WEBHOOK_URL> -c card.json

python3 scripts/send_teams.py <WEBHOOK_URL> -r '{"type": "message", "text": "Custom"}'

scripts/send_teams.py

If you receive errors about a "suspended" workflow:

1. Open Power Automate (or your org's URL)
2. Go to My flows / Workflows
3. Find your workflow → Resume / Activate / Turn on
4. Retry sending your message
