Integrate with Apple Calendars without using CalDAV with the Cronofy Unified Calendar API
There are millions of iPhone users out there.
Allowing them to connect their Apple Calendar to your application creates a better user experience and puts you one step ahead of your competition.
However, it’s not easy.
The only way to connect to iCloud is using CalDAV. This client/server document protocol is used to submit and retrieve Apple Calendar documents.
Unfortunately, CalDAV can be a challenge for developers used to more commonly styled HTTP APIs.
This mean that many applications that could benefit from calendar sync don’t take advantage of it and their users miss out.
Using Cronofy’s unified calendar API, you can solve these problems and more.
Full calendar sync made easy
With traditional calendar integration, two versions of an event exist in two different calendar services.
Both can be updated independently, meaning that if an event is cancelled or rescheduled, one party may miss out on important details.
To avoid conflict deadlocks and infinite update loops, you’re responsible for handling ownership and state transitions.
The Cronofy API resolves these synchronization challenges.
Changes to calendar events are idempotent. You don’t have to worry about if an event already exists or not, you just tell us what state you want to it be in and we’ll make the necessary changes.
Cronofy also differentiates between events sourced from your application (‘Managed’) and events already in the user’s calendars (‘Unmanaged’) to ensure that you have reliable integration from the start.
Deliver great scheduling features to your users
Only allowing users to connect to one calendar service can result in a poor user experience.
It could even mean that they don’t use your product and go to a competitor instead.
Connecting software to multiple calendar services, however, is a costly investment.
You have to spend time not only creating individual connections to each calendar API, but also maintaining those connections and ensuring it works with previous versions of each calendar service.
All the maintenance is handled by us, meaning that you have more time to spend on creating a great product for your customers.
The iCloud Calendar API offers limited connectivity options.
Either your application can access everything in a user’s calendar, or nothing. There is no other option.
Unless you use Cronofy.
With Cronofy, you can customize how much of a user’s calendar your software has access to.
If it only needs their free/busy data, you can set it up so that that’s all it will see.
This free/busy data can be hosted on our EU or US servers.
