A Practical Guide to nylas auth scopes

#cli #authentication #security #devtools

Authentication is the gate between your terminal and your mailbox. nylas auth scopes handles it.

The nylas auth scopes command shows which OAuth permissions are granted for a connected account — email read, email send, calendar access, contacts access, and more. Useful for debugging permission errors or verifying least-privilege access.

How It Works

The CLI stores credentials securely in your system keychain (macOS Keychain, Linux Secret Service, or Windows Credential Manager). Tokens are refreshed automatically — you authenticate once and commands just work.

Syntax 

nylas auth scopes [grant-id]
Enter fullscreen mode Exit fullscreen mode

Examples

Show scopes for active account:

nylas auth scopes
Enter fullscreen mode Exit fullscreen mode

Show scopes for specific grant:

nylas auth scopes grant_abc123
Enter fullscreen mode Exit fullscreen mode

Key Flags

Run nylas auth scopes --help to see all available flags. Add --json for machine-readable output — useful when piping into jq or feeding data to scripts.

nylas auth scopes --help
Enter fullscreen mode Exit fullscreen mode
