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.
Send email attachments up to 150MB on Microsoft (Outlook and Exchange Online) grants using a new pre-upload flow. Upload the file once, then reference it by ID when sending.
You can now restrict what your Agent Accounts send. Block sends to specific recipients, domains, or TLDs before they reach the provider — so an autonomous agent can't email the wrong address on its own.
Agent Accounts are Nylas-hosted email and calendar identities that an AI agent owns end-to-end. Create a real [email protected] mailbox through the API, assign policies and rules to guardrail its behavior, and use every existing Nylas endpoint against the new grant.
Compressed webhook delivery for webhooks, SNS, and Pub/Sub; a new message.created.cleaned trigger for Clean Conversations; and a field-name correction on the IMAP sync completed notification.
Automatic browser language detection for scheduler, translated editor labels, and fixes for EU region API URLs and redirect query parameters.
Updated OpenAPI specs to correctly document nullable fields across Scheduler, Events, Contacts, Availability, Free/Busy, and Attachments APIs.
New Signatures API lets you create, store, and manage reusable HTML email signatures per grant, and attach them automatically when sending messages or creating drafts.
Better scheduler auth error handling, date normalization fixes, and deferred booking ref initialization for private configurations.
Callback URI management, admin auth config fixes, and reduced code duplication across CLI commands.
Adds 'maybe' event status for calendar events and JSON body support for booking deletion.
CLI authentication, disposable email blocking, and authentication reliability improvements.
Adds a scheduling availability API for retrieving availability via the new /v3/scheduling/availability endpoint.
