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.
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.
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.
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.
Adds admin API resources — Policies, Rules, Lists, Workspaces, and Domains — plus Applications update support and request body support on DELETE.
Agent Accounts are now generally available. Provision a dedicated [email protected] 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.
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().
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.
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.
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.
Adds a Node-native stream helper for attachment downloads and a typed `fields` query parameter on `messages.send()` that returns response headers.
Fixes camelCase metadata keys being silently snake_cased on the multipart form-data path used for large send and draft payloads.
Expands the events resource with resources, textDescription, multi-event-type filtering, and select/tentativeAsBusy query params. Adds metadata_pair filtering on list messages, Google Calendar color_id, and expanded notetaker meeting settings. Fixes events-exception parsing, thread ID encoding, scheduler participant defaults, and folder deserialization with select.
Expanded localized scheduler copy, plus React-only fixes for date and time slot clicks and schedulerApiUrl handling on full page refresh.
Adds typed support for Agent Accounts (Policies, Rules, Lists, and the new provider: 'nylas' BYO Auth variant) and resumable upload sessions for large attachments up to 150 MB on Microsoft grants.
Sandbox apps now show a security notice in the hosted auth flow before users grant access. The screen highlights the permissions being requested and gives users a one-click path to report the application to the Nylas security team. Production, Staging, Development, and Shared GCP App flows are unchanged.
New: Notetaker now accepts transcription_settings to force a language or narrow what automatic language detection considers — useful when your users consistently speak one or more languages and auto-detect has been mis-identifying them. Transcripts also return the detected language code.
Send endpoints now accept an Idempotency-Key header so retries don't deliver duplicate emails. Pass a unique key per logical send and Nylas caches the response for 1 hour — safe for workflow engines, background queues, and any client that retries after a network blip.
Fixes scheduler date and time slot clicks when auth props are set after mount, and restores the schedulerApiUrl region on full page refresh in React.
Adds Transactional Send, Manage Domains with service account request signing, and the Policies, Rules, and Lists APIs for Agent Accounts. Fixes camelCase query params on list grants.
