Cloud Custodian (c7n) to Azure Teams Incoming Webhook

Azure-webhook.yml

# Unfortunately we use Teams and I needed a way to deliver a payload to an incoming webhook via Lambda for
# various c7n things.
#
# Below is just an example.


policies:
    - name: call-Azure-webhook
      resource: ec2
      description: |
        Call webhook with list of resource groups
