Teams Webhook Migration Alternative
Webhook-only tools are useful for simple sends, but they do not read Teams state, manage channels, upload files, or expose deterministic JSON output for agents.
CLI replacement shape
teams auth login --device-code
teams message send --team "$TEAM_ID" --channel "$CHANNEL_ID" --body "$BODY" --output json
Why this is different
OSO MS Teams CLI uses Microsoft Graph and can participate in richer workflows: discovery, reads, replies, reactions, files, retries, and error handling.
For fully unattended posting, plan for bot mode rather than client credentials message sends.
