To receive messages from CloudRadar on Microsoft Teams you need to create a so-called incoming web hook on some channel.
On the very left navigation click on "Teams" and select a channel you want the messages to be posted. This can be any existing channel or you create a new one and you name it "CloudRadar Monitoring" for example.
Click on the three dots of a channel to unfold the menu. Click on
Configure of Incoming Webhook.
Give the web hook a name that appears as sender of all messages, for example choose "CloudRadar" as name.
Optionally you can upload a custom image, for example the cloudradar logo.
Click Create and copy the generated URL of the web hook. Use this URL to setup the recipient in my.cloudradar.io.
