Frequently Asked Questions

How hard is calendar integration?

OAuth setup takes time, but APIs are well-documented. Use libraries like google-api and handle token refresh properly. Plan for 3-5 days per calendar.

How do you handle timezones?

Store everything in UTC. Convert for display using the users timezone (detected or selected). Test edge cases thoroughly.

What makes this different from Calendly?

Industry focus (healthcare HIPAA, legal intake), better pricing, specific integrations (CRM, EHR), or features Calendly lacks (group scheduling, resources).
