Frequently Asked Questions

What is the Gmail API?

The Gmail API is a RESTful interface that provides access to all of the data and functionality in Gmail mailboxes, enabling developers to parse email data, create email drafts, send emails, organize an email inbox with labels, modify settings for user accounts, and create filters to automatically label, forward, or archive emails.

At Nylas, we spend a ton of time integrating with third-party APIs, like the Gmail API, to build our email API, so we’re here to offer our expertise about what it takes to build a best-in-class integration with Gmail.

How is the Nylas API integration with the Gmail API secured?

The Nylas Email API encrypts 100% of your data with enterprise-grade security standards. In addition, Nylas is compliant or certified with GPDR, CCPA, SOC 2 Type II, ISO 27001, and HIPAA.

How do I get started integrating with the Gmail API?

Before you can access a Gmail account, you will need to authenticate the account with the appropriate permissions. All Google APIs use OAuth 2.0 for account authentication and authorization, which establishes a login process where your app negotiates with the Google Identity Platform to receive an access token for user accounts. This token provides limited access to user resources based on the scopes the user consented to as part of the authentication process. 

Alternatively, Nylas Hosted Auth auto-detects Google accounts, even for domains other than, and prompts users to sign in and accept the permissions your app needs. Your user’s credentials are stored safely on our SOC 2 Certified infrastructure, and Nylas provides an access token your app can use for Gmail data and functionality.
