Teams Meetings

Use the Teams meeting pipeline when you want Hermes to ingest Microsoft Graph meeting events, fetch transcripts first, fall back to recordings plus STT when needed, and deliver a structured summary to downstream sinks.

This page focuses on setup and enablement:

• Graph credentials
• webhook listener configuration
• Teams delivery modes
• pipeline config shape

For day-2 operations, go-live checks, and the operator worksheet, use the dedicated guide: Operate the Teams Meeting Pipeline.

What This Feature Does

The pipeline:

1. receives Microsoft Graph webhook events
2. resolves the meeting and prefers transcript artifacts first
3. falls back to recording download plus STT when no usable transcript is available
4. stores durable job state and sink records locally
5. can write summaries to Notion, Linear, and Microsoft Teams

Operator actions stay in the CLI (the teams-pipeline subcommand is registered by the teams_pipeline plugin — enable it via hermes plugins enable teams_pipeline or set plugins.enabled: [teams_pipeline] in config.yaml):

hermes teams-pipeline validate
hermes teams-pipeline list
hermes teams-pipeline maintain-subscriptions

Prerequisites

Before enabling the meetings pipeline, make sure you have:

• a working Hermes install
• the existing Microsoft Teams bot setup if you want Teams outbound delivery
• Microsoft Graph application credentials with the permissions required for the meeting resources you plan to subscribe to
• a public HTTPS URL that Microsoft Graph can call for webhook delivery
• ffmpeg installed if you want recording-plus-STT fallback

Step 1: Add Microsoft Graph Credentials

Add Graph app-only credentials to ~/.hermes/.env:

MSGRAPH_TENANT_ID=<tenant-id>
MSGRAPH_CLIENT_ID=<client-id>
MSGRAPH_CLIENT_SECRET=<client-secret>

These credentials are used by:

• the Graph client foundation
• subscription maintenance commands
• meeting resolution and artifact fetches
• Graph-based Teams outbound delivery when you do not provide a dedicated Teams access token

Step 2: Enable the Graph Webhook Listener

The webhook listener is a gateway platform named msgraph_webhook. At minimum, enable it and set a client state value:

MSGRAPH_WEBHOOK_ENABLED=true
MSGRAPH_WEBHOOK_PORT=8646
MSGRAPH_WEBHOOK_CLIENT_STATE=<random-shared-secret>
MSGRAPH_WEBHOOK_ACCEPTED_RESOURCES=communications/onlineMeetings

The listener exposes:

• /msgraph/webhook for Graph notifications
• /health for a simple health check

You need to route your public HTTPS endpoint to that listener. For example, if your public domain is https://ops.example.com, your Graph notification URL would typically be:

https://ops.example.com/msgraph/webhook

Step 3: Configure Teams Delivery and Pipeline Behavior

The meeting pipeline reads its runtime config from the existing teams platform entry. Pipeline-specific knobs live under teams.extra.meeting_pipeline. Teams outbound delivery stays on the normal Teams platform config surface.

Example ~/.hermes/config.yaml:

platforms:
  msgraph_webhook:
    enabled: true
    extra:
      port: 8646
      client_state: "replace-me"
      accepted_resources:
        - "communications/onlineMeetings"

  teams:
    enabled: true
    extra:
      client_id: "your-teams-client-id"
      client_secret: "your-teams-client-secret"
      tenant_id: "your-teams-tenant-id"

      # outbound summary delivery
      delivery_mode: "graph" # or incoming_webhook
      team_id: "team-id"
      channel_id: "channel-id"
      # incoming_webhook_url: "https://..."

      meeting_pipeline:
        transcript_min_chars: 80
        transcript_required: false
        transcription_fallback: true
        ffmpeg_extract_audio: true
        notion:
          enabled: false
        linear:
          enabled: false

Teams Delivery Modes

The pipeline supports two Teams summary-delivery modes inside the existing Teams plugin.

incoming_webhook

Use this when you want a simple webhook post into Teams without channel-message creation through Graph.

Required config:

platforms:
  teams:
    enabled: true
    extra:
      delivery_mode: "incoming_webhook"
      incoming_webhook_url: "https://..."

graph

Use this when you want Hermes to post the summary through Microsoft Graph into a Teams chat or channel.

Supported targets:

• chat_id
• team_id + channel_id
• team_id + home_channel fallback for the existing Teams platform

Example:

platforms:
  teams:
    enabled: true
    extra:
      delivery_mode: "graph"
      team_id: "team-id"
      channel_id: "channel-id"

Step 4: Start the Gateway

Start Hermes normally after updating config:

hermes gateway run

Or, if you run Hermes in Docker, start the gateway the same way you already do for your deployment.

Check the listener:

curl http://localhost:8646/health

Step 5: Create Graph Subscriptions

Use the plugin CLI to create and inspect subscriptions.

Examples:

hermes teams-pipeline subscribe \
  --resource communications/onlineMeetings/getAllTranscripts \
  --notification-url https://ops.example.com/msgraph/webhook \
  --client-state "$MSGRAPH_WEBHOOK_CLIENT_STATE"

hermes teams-pipeline subscribe \
  --resource communications/onlineMeetings/getAllRecordings \
  --notification-url https://ops.example.com/msgraph/webhook \
  --client-state "$MSGRAPH_WEBHOOK_CLIENT_STATE"

:::warning Graph subscriptions expire in 72 hours

Microsoft Graph caps webhook subscriptions at 72 hours and will not auto-renew them. You MUST schedule hermes teams-pipeline maintain-subscriptions before going live, or notifications will silently stop three days after any manual subscription creation. See Automating subscription renewal in the operator runbook — three options (Hermes cron, systemd timer, plain crontab).

:::

For subscription maintenance and day-2 operator flows, continue with the guide: Operate the Teams Meeting Pipeline.

Validation

Run the built-in validation snapshot:

hermes teams-pipeline validate

Useful companion checks:

hermes teams-pipeline token-health
hermes teams-pipeline subscriptions

Troubleshooting

Problem	What to check
Graph webhook validation fails	Confirm the public URL is correct and reachable, and that Graph is calling the exact /msgraph/webhook path
Jobs do not appear in hermes teams-pipeline list	Confirm msgraph_webhook is enabled and that subscriptions point at the right notification URL
Transcript-first never succeeds	Check Graph permissions for transcript resources and whether the transcript artifact exists for that meeting
Recording fallback fails	Confirm ffmpeg is installed and the Graph app can access recording artifacts
Teams summary delivery fails	Re-check delivery_mode, target IDs, and Teams auth config
