Syncing calendar data to and from Exchange-based email applications is a difficult problem to solve. It’s especially difficult to build a system that lets you know about an event change in a matter of seconds.

In other words, it’s no big secret that creating an effective and secure Exchange calendar syncing feature is no easy feat. In fact, building a feature for just one calendar provider can take 12 months or more.

With the Nylas Calendar API, developers can build apps with seamless connectivity with ease.

Exchange is a famously complex protocol to implement — and with lengthy, hermetic documentation. In many cases, developers spend a bunch of time reverse-engineering the protocol to make it work. Integrating your application with the Nylas Calendar API lets you build scheduling and calendar functionality across

In fact, building scheduling features with the Nylas Google Calendar API just requires 4 lines of code across NodeJS, Python, and Ruby.



const Nylas = require('nylas');   Nylas.config({ appId: APP_ID, appSecret: APP_SECRET, });   var nylas = Nylas.with(ACCESS_TOKEN);{in:'inbox'}).then(count => { console.log('There are ${count} events in your inbox.'); });


from nylas import APIClient   nylas_client = APIClient(APP_ID, APP_SECRET, token) for event in, limit=5): print(event.title)


require 'nylas',app_secret:APP_SECRET, access_token:ACCESS_TOKEN)"Hello!").each do |event| puts event.title end
