Choose the right API approach for you

Trusted by developers to schedule hundreds of millions of interviews, Cronofy's scheduling platform offers two modes built upon the same high-performance, reliable scheduling infrastructure.




Embedded Scheduler

## Accelerate development time by embedding our scheduler into your own application

Fully managed scheduling tooling for your users. Each user has a Cronofy Account which allows them to manage their working hours, conferencing and other preferences. Companies and teams use Cronofy to setup complex scheduling rule and workflows.

The Scheduler API allows you to leverage all of this setup and configuration and deliver it embedded deeply into your application.

This is the option to choose when you want to enable all of the Cronofy scheduling features for your users with minimal effort and the quickest time to market.

Access multiple API endpoints that allow you to craft a completely tailored interview scheduling experience for your users. Complex multi-person availability lookups, working hours management, realtime syncing of calendar changes, and fully customizable UI Elements to accelerate your feature delivery.

> We set up a deep calendar integration which enables our customers to easily manage interviews and schedules. Cronofy allows us to display room and employee availability inside Personio. Booking time slots with rooms has become so simple. Our users also love that they can track who accepted or declined interview invites. This way they have all necessary information in one central place and save valuable time.
