# ByDoctor API: Clinic Management Integration Reference

> Integrate your systems with ByDoctor's clinic management platform. Access appointments, patients, payments, and real-time webhook events.

ByDoctor is a Brazilian clinic management platform that provides a public REST API and webhook system so you can integrate external tools, automate workflows, and synchronize data with your own systems. This documentation covers everything you need to build integrations against the ByDoctor API — from authentication to real-time event subscriptions.
