Gmail API

The Gmail API is a RESTful service: programmatically manage Gmail mailboxes, execute CRUD operations on messages and threads, and automate sending with a 1 billion unit daily quota.

The Gmail API provides a powerful, RESTful interface for deep integration with a user's Gmail mailbox. Use it to programmatically execute CRUD operations on core resources: messages, threads, drafts, and labels. Developers leverage the API for critical tasks like mail extraction, automated message sending, and account migration. You can manage attachments, apply system labels (e.g., `INBOX`), and utilize push notifications via Google Cloud Pub/Sub for real-time updates. The system enforces a substantial daily quota of 1 billion quota units, with methods like `messages.send` costing 100 units.
