# Nylas Node.js SDK v8.4.0

Source: https://developer.nylas.com/docs/changelogs/2026-06-24-nylas-nodejs-v8-4-0/

## Added

- **Transactional send API**: a new `nylas.transactionalSend` resource adds `send()` for domain-based transactional email against [`POST /v3/domains/{domainName}/messages/send`](/docs/reference/api/manage-domains/). Use it to send transactional messages from a verified domain.
- **`calendarId` and `eventId` on `Notetaker`**: the `Notetaker` model now exposes optional `calendarId` and `eventId` fields, so you can associate a notetaker session with the calendar and event it was created for.

## Fixed

- **Truncated message webhook triggers**: `message.created.truncated` and `message.updated.truncated` are now part of the `WebhookTriggers` enum, so you can subscribe to truncated message notifications with full type support.
- **Missing webhook trigger types**: the `WebhookTriggers` enum now includes `message.deleted`, `message.created.cleaned`, `grant.imap_sync_completed`, the Notetaker triggers, the Agent Account and transactional deliverability triggers, and the legacy tracking triggers.

## Changed

- **Dependencies**: bumped dependencies to their latest reasonable versions.
