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 next to "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 set up the recipient in my.cloudradar.io.
Back on my.cloudradar.io insert the copied URL into the field "Connector URL of incoming Webhook".
