To use Microsoft Teams Admin integration in n8n, start by adding the HTTP Request node to your workflow canvas and authenticate it using a generic authentication method. Once connected, you can make custom API calls to Microsoft Teams Admin to query the data you need using the URLs you provide, for example: you can use the authenticated HTTP Request node to create new teams, update existing settings, or retrieve data such as team members or channel lists. For instance, to create a new team, send a POST request to the corresponding Microsoft Teams Admin API endpoint with the necessary payload. Similarly, you could implement a GET request to fetch users' status or activity reports for monitoring purposes.
