Application and workspace admin APIs: manage applications and workspaces from the SDK.
applications.update() for PATCH /v3/applications.
Redirect URI updates corrected to PATCH /v3/applications/redirect-uris/{id}.
A Workspaces resource for /v3/workspaces CRUD, plus auto_group and manual_assign.
Callback URIs in application updates: UpdateApplicationRequest now accepts callback_uris, and a new UpdateApplicationRedirectUriRequest exposes optional id, platform, and settings. Include an existing callback URI id to preserve or update an entry. Workspace auto-grouping also gains invalid_also support.
Microsoft Graph large attachment support: a resumable upload-session flow sends attachments up to 150 MB on Microsoft (Graph) grants, mirroring the Node.js SDK.
attachments.create_upload_session(identifier, request_body) returns a pre-signed url and an attachment_id.
Upload the file bytes directly to that URL, then call attachments.complete_upload_session(identifier, attachment_id) to finalize it.
Reference the attachment_id in messages.send() or drafts.create(). See the create and complete upload-session references.
JSON Content-Type header: JSON requests now send Content-Type: application/json without the ; charset=utf-8 parameter that the Nylas API rejected. This fixes draft creation and other JSON requests that previously failed with “only JSON and multipart supported.”
