How to Get Full Calendar Sync & CRUD with the Nylas Calendar API

6 min read

    Need to build a calendar integration? Power your application with real-time, secure calendar sync with as little as four lines of code. Find out how the Nylas Calendar API can help.

    We have several meetings and appointments to keep track of on a daily basis, be it personal or professional. We heavily rely on our calendars to track our events. Come to think of it, all of the events in our lives are actually scattered between different calendar providers.

    All these calendars have their own systemic features that process data in different ways. We would need to build independent connections for individual providers. On top of that, we’d also have to maintain those connections and ensure the software works with past, present, and future versions of every provider’s API updates (sometimes they introduce breaking changes that hinder their functionality).

    You have the choice to build unique connections with every individual calendar provider, or you can use the Nylas Calendar API and save months of developer time through one simple integration.

    This way, you can spend more time focusing on the features you love to build.

    Our Calendar API powers your application with real-time, secure calendar sync. Why is it important you ask? It’s important because building scheduling and calendar sync features are mission-critical for many software companies.

    Without Nylas, developers could easily take 12 months or more to build these connections with each calendar provider where the infrastructure varies between Gmail,, Exchange, Office 365 and the rest.

    In this post, we will see how you can avoid all that by diving into some of the features and functionality of our Calendar API.


    The Nylas Calendar API

    The Nylas Calendar API acts as a layer of abstraction on top of all the calendar providers. You can streamline the scheduling process and updates in real-time.

    When an account authenticates to Nylas, one of our sync servers will claim the account and automatically start syncing calendar data into Nylas’ database. Each account connected to Nylas can have multiple calendars, and each calendar can have a collection of individual events.

    The calendar API accesses all of the information to secure a time that fits everyone’s schedule. It can also give the person you’re meeting with access to your calendar and lets them choose the time that works best.

    Once the appointment slot is reserved, the calendar is updated instantly, so there is never a chance of double booking or missing a meeting. Calendar Connectivity

    If you’re building a software that needs calendar connectivity with, the APIs, services, and templates often end up causing more dependencies than solutions.

    The Nylas Calendar API abstracts away all of the complexity of building an app that integrates with calendars and handles all product changes and API modifications, so you don’t experience outages or service disruptions.

    Nylas streamlines calendar sync from and every other calendar provider (Gmail, Exchange, Office 365, and the rest) giving you a dependable API that intelligently adapts to any changes the calendar providers introduce.

    Using the API, you have full CRUD (Create, Read, Update, and Delete) capabilities through powerful API primitives. In addition to these, Nylas powers all the calendar features your customers require.


    Booking and Cancellation

    By having access to all the synced calendars and real-time updates, reservations and cancellations become easily manageable. From single events on team calendars to custom recurring events, the Nylas Calendar API handles it all.

    You can update your plans from your calendar, and the changes will be reflected on the schedules of everyone affected in real-time.

    Appointment Reminders and Task Scheduling 

    Whatever the reason behind a missed appointment, it can get expensive for your company. With Nylas, everyone gets automated appointment reminders to remind all parties of scheduled meetings.

    The integration also has access to all the calendars which makes it easier to schedule tasks and makes deadline management a breeze.

    Productivity Analytics 

    The API also receives productivity data by analyzing cross-team availability. It pulls data from the calendar and calculates the open rate, the click-through rate, the email usage (how many emails were sent and received) and the calendar meetings (how frequently the meetings were scheduled). It collects all this data to determine how time is being spent  and helps provide a solution for how it can be improved.

    Quick-start SDKs

    With Nylas, you don’t have to build a calendar integration from scratch. We offer a suite of SDKs to get you started quickly so you can spend more time iterating features to your users’ exact specifications.

    We offer SDKs in three core languages: Ruby, Node JS, and Python. With just a few lines of code, you can integrate Nylas into your app faster, maintain higher code quality, and free up time for building core features.


    Security and Privacy

    Enterprise-grade security and privacy controls have always been at the heart of what we do. The Nylas Calendar API encrypts 100% of data with military-grade security standards.

    Here are some of the ways we protect and secure data in our infrastructure:
