Save Months of Time With the Nylas API for Google Calendar


We built the Nylas Calendar API to make it easy for developers to build apps that connect to user's Google Calendars. 

With Nylas, you can built a more secure, stable connection to Google Calendar data that provides a reliable service even when Google Calendar itself experiences an outage.

Our API comes out-of-the-box with security certifications, and eliminates the need for ongoing support and maintenance costs.


Add Calendar Sync in 4 Lines of Code

import Nylas from 'nylas';   Nylas.config({ appId: APP_ID, appSecret: APP_SECRET, });   var nylas = \Nylas.with(ACCESS_TOKEN);   nylas.threads .count({in:'inbox'}) .then(count => { console.log( `There are ${count} events in your inbox.` ); });
from nylas import APIClient   client = APIClient( APP_ID, APP_SECRET, token, ) threads = \client.threads.where( unread=True, limit=5, )  for thread in threads: print(thread.subject)
require 'nylas'   nylas = app_id: APP_ID, app_secret: APP_SECRET, access_token: ACCESS_TOKEN )   threads = nylas"Hello!")   threads.each do |thread| puts thread subject end

Enterprise-Grade Security


The Nylas Calendar API gives you even more control over the types of Google Calendar data you sync than the Google Calendar API offers. 

Syncing more data than your users need can leave you open to security vulnerabilities and loses user trust.

With the Nylas Calendar API, you can request read only access, or modify permissions depending on your integration requirements.

Nylas is also SOC 2 certified, Privacy Shield Certified, GDPR-compliant, and HIPAA and FINRA-ready. Data is encrypted in transit and at rest with enterprise-grade security standards.
