Changelogs

Agent Account metadata
Agent Account metadataAgent AccountsEmailCalendar

Agent Account grants now support the metadata object on Events, Messages, and Drafts. Attach up to 50 key-value pairs per object and filter by the five reserved keys with metadata_pair, the same way connected grants do.

Agent Accounts in Scheduler
Agent Accounts in SchedulerAgent AccountsSchedulerCalendar

Agent Account grants can now own a Scheduler Configuration and act as the organizer, so an agent hands out its own booking link and takes bookings on its own calendar. Round-robin Configurations and non-primary calendars aren't supported yet.

iCloud CalDAV error code fix

iCloud CalDAV requests that fail with an authorization error now correctly return a 403 Forbidden response instead of a 504 Gateway Timeout, making permission issues easier to distinguish from timeouts.

Notetaker transcript fix

Fixed an issue where the Notetaker media endpoint reported no transcript available for a small number of meetings that already had a transcript.

Calendar owner_email field

The Calendar object now includes an owner_email field on Microsoft grants, naming the account that owns each calendar. Use it with is_owned_by_user to tell a user's own calendars apart from the ones shared with them.

CLI v3.1.30

Adds nylas email subscriptions commands to discover newsletter and mailing-list subscriptions from List-Unsubscribe headers, preview and open their unsubscribe actions, and clean up matching messages, for Google and Microsoft grants.

Java SDK v2.18.1

Adds TrackingOptions.domainName to send with a custom tracking domain for link and open tracking, and fixes attendees and anyEmail filters silently keeping only the last value when multiple values were passed.

Agent Account message headers

Agent Account grants now support both fields header options. Read the full header set with fields=include_headers, or just Message-ID, In-Reply-To, and References with fields=include_basic_headers, on message get and send requests.

@nylas/web-elements v2.5.17

Fixes the scheduler showing a misleading API request failed error after a booking was successfully cancelled, even though the cancellation succeeded.

Agent Account email search
Agent Account email searchAgent AccountsEmail

Agent Account grants now support full-text search on the Messages and Threads endpoints. One relevance-ranked query searches subjects, participants, visible body text, and attachment filenames with Boolean operators, quoted phrases, grouping, and negation.

Scheduler change attribution

New: Scheduler now stamps scheduler_last_start, scheduler_last_end, and scheduler_updated_at metadata on the events it books. Compare them against event.updated payload times to tell Scheduler reschedules apart from direct calendar edits.

Notetaker keyword hints
Notetaker keyword hintsNotetakerCalendar

New: Notetaker transcription_settings now accepts keywords and use_speaker_names_as_keywords to bias transcription toward names, acronyms, and product names it would otherwise mis-hear. Language and keyword hints are independent.

Node.js SDK v8.4.0

Adds nylas.transactionalSend.send() for domain-based transactional email, plus calendarId and eventId on the Notetaker model. Fixes the WebhookTriggers enum with truncated message triggers and a batch of previously missing trigger types, and bumps dependencies to their latest versions.

Ruby SDK v6.8.0

Adds admin API resources — Policies, Rules, Lists, Workspaces, and Domains — plus Applications update support and request body support on DELETE.

Agent Accounts (GA)
Agent Accounts (GA)Agent AccountsEmailCalendar

Agent Accounts are now generally available. Provision a dedicated name@yourdomain.com mailbox and calendar for an AI agent with a single API call, guardrail it with Policies, Rules, and Lists, and run it against every standard Nylas endpoint.

Node.js SDK v8.3.0

Adds the htmlAsMarkdown option to messages.clean(), plus the typed Workspaces, Agent Account Lists, and Manage Domains admin APIs and an icalUid event filter from v8.2.0. Fixes Applications and Rules field naming, the Rules list response envelope, and enables field-set reduction in threads.find().

Python SDK v6.16.0

Adds application and workspace admin APIs (applications.update() and Workspaces CRUD), callback URI support in application updates, and Microsoft Graph large attachment upload sessions. Fixes the JSON Content-Type header so draft and other JSON requests aren't rejected.

Java SDK v2.17.0

Adds application administration to the SDK: Applications.update(), Manage Domains admin CRUD with Nylas Service Account signing, and a Workspaces resource. Introduces transactional email via Domains.sendTransactionalEmail(), plus app-level Policies, Rules, and Lists resources for Agent Accounts.

Headers on Send + include_basic_headers

Get RFC threading headers on the Send Message response without a follow-up GET call. A new fields=include_basic_headers option returns just Message-ID, In-Reply-To, and References — across List Messages, Get Message, and Send Message — for a much smaller payload than the full header set.

Node.js SDK v8.1.2

Adds a Node-native stream helper for attachment downloads and a typed `fields` query parameter on `messages.send()` that returns response headers.
