Gmail API Introduces Granular OAuth Scopes

Developers can now utilize fine-grained permissions such as https://www.googleapis.com/auth/gmail.drafts.create for composing drafts, https://www.googleapis.com/auth/gmail.messages.readonly for reading emails, https://www.googleapis.com/auth/gmail.labels.create for label management, and https://www.googleapis.com/auth/gmail.settings.filters.readonly for filter access. Numerous methods across users.drafts, users.messages, users.labels, users.threads, and users.settings.filters have been updated to list these new, specific scopes as primary options. While broader scopes like gmail.modify and gmail.readonly are still supported, developers are strongly encouraged to review their applications and migrate to these more targeted scopes to improve security posture and user trust.
