Under the Hood: An Agent Account Is Just a Grant

Short summary

Nylas Agent Accounts reuse the existing grant abstraction meant for OAuth-connected accounts, eliminating separate API endpoints or schemas. Message, calendar, contact, and event operations work identically for AI agents as for human users—same webhooks, CRUD patterns, and auth. Developers can reuse existing handlers by branching on the grant's provider field, trading off immutable system folders and soft deletes for integration simplicity.

• •Agent Accounts use the same /v3/grants/* API endpoints as OAuth accounts—no separate integration path
• •Full mailbox, calendar, contact, and webhook support with IMAP/SMTP access for supervised operation
• •Inherited quirks: system folders immutable, deletes soft, templates and smart compose unsupported
