Using Nylas Notetaker

Looking for the Notetaker API references? You can find them here!

Nylas Notetaker is a real-time meeting bot that you can invite to online meetings to record and transcribe your discussions.

How Notetaker works

When you invite Notetaker to a meeting, it joins the session as a user and records your discussion. It then transcribes your meeting and sends status updates to you using webhook notifications.

Notetaker sends a message to attendees using the meeting provider’s messaging function a few minutes after joining the call. This message informs users that Notetaker is recording and transcribing the meeting, and that it’s the meeting host’s responsibility to collect consent.

Notetaker can join meetings in three ways:

Notetaker records the meeting until you either remove it from the session or the meeting ends. Then, it processes the data it recorded. Nylas sends notetaker.media webhook notifications as each processed file becomes available for download.

Set up Notetaker

To follow along with the samples on this page, you first need to sign up for a Nylas developer account, which gets you a free Nylas application and API key.

For a guided introduction, you can follow the Getting started guide to set up a Nylas account and Sandbox application. When you have those, you can connect an account from a calendar provider (such as Google, Microsoft, or iCloud) and use your API key with the sample API calls on this page to access that account’s data.

Set up Notetaker notifications

Nylas can send webhook notifications about Notetakers, like when they join calls and when recordings are available. You can set this up through the Nylas Dashboard or by making a POST /v3/webhooks request with your webhook_url and the trigger types you want to subscribe to. You can subscribe to the following Notetaker webhook triggers:

Invite Notetaker to a meeting

Notetaker currently supports Google Meet, Microsoft Teams, and Zoom sessions.

When you’re ready, invite Notetaker to a meeting by making a POST /v3/notetakers or POST /v3/grants/<NYLAS_GRANT_ID>/notetakers request with a link to your session. The join_time is an optional parameter. If you leave it blank, Notetaker joins the meeting immediately.

When you invite Notetaker to a meeting, Nylas sends a notetaker.meeting_state webhook notification showing that it’s attempting to join.

{
  "specversion": "1.0",
  "type": "notetaker.meeting_state",
  "source": "/nylas/notetaker",
  "id": "<WEBHOOK_ID>",
  "time": 1737500935555,
  "webhook_delivery_attempt": 0,
  "data": {
    "application_id": "<NYLAS_APPLICATION_ID>",
    "object": {
      "id": "<NOTETAKER_ID>",
      "grant_id": "<NYLAS_GRANT_ID>",
      "calendar_id": "<CALENDAR_ID>",
      "event": {
        "ical_uid": "<ICAL_UID>",
        "event_id": "<EVENT_ID>",
        "master_event_id": "<MASTER_EVENT_ID>"
      },
      "object": "notetaker",
      "state": "connecting",
      "meeting_state": "dispatched"
    }
  }
}

Notetaker is always considered a non-signed-in user on the meeting platform. If your meeting is limited to organization members only, you need to approve Notetaker when it tries to join. If you don’t approve its join request within 10 minutes of the scheduled join time, it times out and sends a notetaker.meeting_state webhook notification with the status set to failed_entry.

Nylas doesn’t de-duplicate Notetaker bots. Every POST /v3/notetakers or POST /v3/grants/<NYLAS_GRANT_ID>/notetakers request you make invites a new Notetaker to the specified meeting.

Get a list of scheduled Notetakers

You can make a GET /v3/notetakers or GET /v3/grants/<NYLAS_GRANT_ID>/notetakers request to get a list of scheduled Notetaker bots.

curl --request GET \
  --url "https://api.us.nylas.com/v3/grants/<NYLAS_GRANT_ID>/notetakers" \
  --header 'Accept: application/json, application/gzip' \
  --header 'Authorization: Bearer <NYLAS_API_KEY>'

Cancel a scheduled Notetaker

If you no longer need Notetaker in an upcoming meeting, you can make a DELETE /v3/notetakers/<NOTETAKER_ID>/cancel or DELETE /v3/grants/<NYLAS_GRANT_ID>/notetakers/<NOTETAKER_ID>/cancel request to cancel the scheduled Notetaker bot.

curl --request DELETE \
  --url "https://api.us.nylas.com/v3/grants/<NYLAS_GRANT_ID>/notetakers/<NOTETAKER_ID>/cancel" \
  --header 'Accept: application/json, application/gzip' \
  --header 'Authorization: Bearer <NYLAS_API_KEY>'

Remove Notetaker from a meeting

Notetaker continues recording your meeting until you either remove it from the session or end the meeting, then it processes the recorded data. If you want to stop recording your meeting before it ends, you can make a POST /v3/notetakers/<NOTETAKER_ID>/leave or POST /v3/grants/<NYLAS_GRANT_ID>/notetakers/<NOTETAKER_ID>/leave request to remove Notetaker from your session.

curl --request POST \
  --url "https://api.us.nylas.com/v3/grants/<NYLAS_GRANT_ID>/notetakers/<NOTETAKER_ID>/leave" \
  --header 'Accept: application/json, application/gzip' \
  --header 'Authorization: Bearer <NYLAS_API_KEY>'

Nylas sends a notetaker.meeting_state webhook notification when Notetaker is removed from a meeting.

{
  "specversion": "1.0",
  "type": "notetaker.meeting_state",
  "source": "/nylas/notetaker",
  "id": "<WEBHOOK_ID>",
  "time": 1737500935555,
  "webhook_delivery_attempt": 0,
  "data": {
    "application_id": "<NYLAS_APPLICATION_ID>",
    "object": {
      "id": "<NOTETAKER_ID>",
      "grant_id": "<NYLAS_GRANT_ID>",
      "calendar_id": "<CALENDAR_ID>",
      "event": {
        "ical_uid": "<ICAL_UID>",
        "event_id": "<EVENT_ID>",
        "master_event_id": "<MASTER_EVENT_ID>"
      },
      "object": "notetaker",
      "status": "disconnected",
      "meeting_state": "api_request"
    }
  }
}

Download processed files

Notetaker can currently recognize up to 10 speakers per transcription.

If you’re subscribed to notetaker.media webhook notifications, Nylas sends a notification when a meeting recording or transcription is processing, available to download, or deleted. You can use the media.recording and media.transcript URLs to download the files when they’re available.

{
  "specversion": "1.0",
  "type": "notetaker.media",
  "source": "/nylas/notetaker",
  "id": "<WEBHOOK_ID>",
  "time": 1737500935555,
  "webhook_delivery_attempt": 0,
  "data": {
    "application_id": "<NYLAS_APPLICATION_ID>",
    "object": {
      "id": "<NOTETAKER_ID>",
      "object": "notetaker",
      "state": "available",
      "media": {
        "recording": "<RECORDING_URL>",
        "transcript": "<TRANSCRIPT_URL>"
      }
    }
  }
}

You can also download the processed meeting files by making a GET /v3/notetakers/<NOTETAKER_ID>/media or GET /v3/grants/<NYLAS_GRANT_ID>/notetakers/<NOTETAKER_ID>/media request. Nylas responds with a link to the recording and a link to the transcript, if available. The links are valid for up to an hour; after that, you need to make another request to get the updated links.

Nylas stores Notetaker media files for a maximum of three days. After the three-day storage period, the files are deleted and you can’t retrieve them using the Nylas API.
