EventSync Calendar API: Seamless Calendar Integration

EventSync Calendar API is a robust solution for developers and businesses looking to unify calendar management across multiple platforms. Whether you’re building a scheduling app, automating event workflows, or syncing team calendars, EventSync simplifies the process with a single, easy-to-use API.

Why EventSync?

EventSync eliminates the complexity of working with multiple calendar APIs. Instead of integrating Google Calendar, Outlook, and Apple Calendar separately, you connect to EventSync once and gain access to all platforms. This reduces development time, minimizes errors, and ensures consistency across your application.

Core Features

• Unified API: Interact with Google Calendar, Outlook, and Apple Calendar through a single endpoint.
• Real-Time Sync: Events are synchronized in real time, ensuring all calendars stay up to date.
• Webhook Support: Receive instant notifications for event changes, cancellations, or new bookings.
• Conflict Detection: Automatically identify and resolve scheduling conflicts across connected calendars.
• Customizable Permissions: Control read/write access for different users or applications.

Use Cases

• Scheduling Apps: Build apps that allow users to book appointments across multiple calendars.
• Team Coordination: Sync team calendars to avoid conflicts and streamline meeting scheduling.
• Automation Workflows: Trigger actions (e.g., sending reminders or updating CRM systems) based on calendar events.
• Customer Engagement: Integrate calendars with customer portals for seamless appointment management.

EventSync is designed for scalability, supporting everything from small startups to enterprise-level applications. The API is RESTful, well-documented, and backed by 99.9% uptime.

Getting Started

Step 1: Sign Up for an API Key

Visit the EventSync Developer Portal and sign up for a free account. Navigate to the API Keys section and generate a new key for your application.

Step 2: Install the SDK

EventSync provides SDKs for popular languages like JavaScript, Python, and Ruby. Install the SDK for your preferred language:

npm install eventsync-sdk
# or
pip install eventsync

Step 3: Authenticate Your Users

Use OAuth 2.0 to authenticate users with their calendar platforms. Redirect users to the EventSync authorization endpoint:

const authUrl = eventsync.auth.getAuthUrl({
  scope: ['calendar.read', 'calendar.write'],
  redirectUri: 'YOUR_REDIRECT_URI'
});

Exchange the authorization code for an access token:

const token = await eventsync.auth.getToken('AUTH_CODE');

Step 4: Sync Calendars

List all connected calendars for a user:

const calendars = await eventsync.calendars.list();

Sync events from a specific calendar:

const events = await eventsync.events.list({ calendarId: 'CALENDAR_ID' });

Step 5: Set Up Webhooks

Register a webhook endpoint in your application to receive event updates. Subscribe to events using the EventSync API:

await eventsync.webhooks.subscribe({
  url: 'YOUR_WEBHOOK_URL',
  events: ['event.created', 'event.updated']
});

Step 6: Handle Conflicts

Enable conflict detection in your API settings. Use the conflicts endpoint to check for overlaps before creating events:

const conflicts = await eventsync.events.checkConflicts({
  startTime: '2026-01-20T10:00:00Z',
  endTime: '2026-01-20T11:00:00Z'
});
