Unified.to alternative with a calendar API
Unified.to covers many categories, from HR to CRM to messaging. Apiroc covers one: calendars. That focus means deeper calendar features, native iCloud Calendar support, real-time webhooks and pricing built for calendar integrations.
Unified.to alternative
What does Apiroc offer as a Unified.to alternative?
Google Calendar, Outlook, iCloud Calendar and CalDAV servers have different APIs, different data models and different surprises. Apiroc gives you one unified calendar API so you can focus building your product, not dealing with calendar apis.

Multi-provider
Outlook, Google Calendar and iCloud Calendar support
Apiroc is a calendar-specific API. It connects Google Calendar, Microsoft Outlook (Office 365, Exchange and Outlook.com) and Apple iCloud Calendar through one API, with the same request and response shapes for every provider.
Reliability
Built by a team that lives in calendar APIs
We have spent years working with the Google, Microsoft and Apple calendar APIs, and Apiroc runs on infrastructure that has processed billions of calendar API calls. Automatic retries, rate limit handling and failover are part of the product.
Webhooks
Your app and webhooks
Webhooks let your app react the moment a calendar changes. Apiroc delivers signed notifications for Google Calendar and Outlook in one consistent format, so you do not need to poll. Webhooks for iCloud Calendar are planned.
Pricing
Pricing that scales with you
Calendars are usually one part of your product, so Apiroc is priced accordingly. The free plan includes 10 End User Accounts. Pro is $25 per month with 50 accounts included and $0.50 per additional account. Enterprise plans add volume discounts and custom limits.
