Introducing the new Gmail API
June 25, 2014
For a while now, many of you have been asking for a better way to access data to build apps that integrate with Gmail. While IMAP is great at what it was designed for (connecting email clients to email servers in a standard way), it wasn’t really designed to do all of the cool things that you have been working on, which is why this week at Google I/O, we’re launching the beta of the
new Gmail API
.
Designed to let you easily deliver Gmail-enabled features, this new API is a standard Google API, which gives RESTful access to a user’s mailbox under OAuth 2.0 authorization. It supports CRUD operations on true Gmail datatypes such as messages, threads, labels and drafts.
As a standard Google API, you make simple HTTPS calls and get your responses in JSON, XML or Google Protobuf formats. You can also make these calls from standard web languages like Java and Python without using a TCP socket, which means the API is accessible from many cloud environments that couldn’t support IMAP.
In contrast to IMAP, which requires access to all of a user’s messages for all operations, the new API gives fine-grained control to a user’s mailbox. For example, if your app only needs to send mail on behalf of a user and does not need to read mail, you can limit your permission request to send-only.
To keep in sync, the API allows you to query the inbox change history, thereby avoiding the need to do “archaeology” to figure out what changed.
Finally, a huge benefit is speed. While there’s still some tuning to be done (“beta” - remember?), results from our tests and feedback from pre-release developers suggest that the new Gmail API is delivering dramatic performance improvements over IMAP for web application use cases.
Check out the launch video and get started with samples, tutorials, and API references at

. We can’t wait to see what you build.
