The API for Google Calendar is a detailed, effective tool for managing the integration of one of the web’s key calendar services. In addition to being a toolkit for Google Calendar events, it also provides the means for integrating objects like access controls.
However, as great as it is, Google’s API also has some significant limitations...
Calendar integration is fundamentally a synchronization problem.You have two representations of an event existing in two application domains, both of which can be updated independently. In order to avoid conflit deadlocks and infinite update loops you have to carefully manage ownership and state transitions.
Unlike the Google Calendar API, the Cronofy API is built to resolve these synchronization challenges. Events upserts and deletes are idempotent. We also differentiate between events sourced from your application (‘Managed’) and events already in the user’s calendars (‘Unmanaged’) to ensure you have a reliable integration out of the box.
The Google Calendar API only provides binary access to calendar data. You can read everything or nothing. So if you want to provide rich calendar integration you have to face up to the challenges of managing that personal data in a safe and secure way.
It’s overly painful to integrate with more calendar services, e.g. iCloud or Exchange. This means all end users must be forced to use Google Calendar regardless of their preferences or needs, or that several calendar APIs need to be managed independently of each other - a costly, time-consuming, unreliable and demanding approach.
Even if you’re not planning integrations with other calendar services right now, it’s good to have that ability on hand in case it’s needed as businesses and projects change direction. Maintaining multiple calendar integrations manually is a headache, but just using one of those APIs is risky.
Happily, these Google Calendar API problems can be solved easily: with Cronofy.
