What an iTeam agent does with the Microsoft Teams API
Agent in the department channel
The finance agent answers questions about payments in the team channel, checking the ERP.
Approval in Teams
When a process needs approval, the manager gets the message in Teams and approves or declines right there.
Meeting summary
With the transcript enabled, the agent summarizes the meeting and posts the decisions and tasks in the project channel.
Project team created
At the start of a project, the agent creates the team and the standard channels, and adds the members.
From the credential to the agent at work, with approval
Register the app in Entra ID
IT creates the application with minimal permissions and publishes the iTeam bot in the organization's catalog.
Connect it in iTeam
Credentials stay in the vault, and each agent works only in the channels and chats it was added to.
Test with approval
Start in a pilot channel. Creating teams and mass messages go through approval.
