Yes. AddEvent has a full REST API that lets you create, update, and manage events and calendars programmatically - without touching the dashboard.

What you can do with the AddEvent API

• Create events from your own system - CRM, booking platform, database, or any backend
• Update events - change details, reschedule, or cancel events programmatically
• Manage calendars - create subscription calendars and add events to them via code
• Retrieve events and calendar data - pull event details back into your system
• Access RSVP attendee data - retrieve registrations and attendee information programmatically
• Trigger Add to Calendar functionality - embed Add to Calendar directly in your application flow

Who it's designed for

Teams who need to integrate AddEvent into a custom application, booking system, CRM, or automated workflow rather than creating events manually in the dashboard. Common use cases:

• A SaaS platform that auto-creates calendar events when a user books a session
• A healthcare system that pushes appointment events to patient calendars at booking time
• An e-commerce platform that adds shipping-window or delivery events automatically
• An event management platform that syncs its event database to AddEvent for calendar distribution

Getting started with the API

Full documentation is available at addevent.com/c/documentation. You'll need an API token from your account settings.

Plan availability

API access is included on Small Business, Professional, and Enterprise plans. It is not available on the free Hobby plan.

Zapier as a no-code alternative

If you need integrations without writing code, the AddEvent + Zapier integration connects AddEvent to 6,000+ apps - including Google Sheets, HubSpot, Salesforce, Slack, and more - without touching the API directly.
