Build Custom Integrations with Our REST API
SchedulingKit is built API-first. Our comprehensive REST API gives developers full programmatic access to bookings, availability, events, contacts, and team management. Real-time webhooks push booking events to your systems the moment they happen — no polling required. Build custom dashboards, sync data with your CRM or EHR, create internal tools, or embed scheduling into your own product. Detailed documentation, SDKs, and sandbox environments make integration straightforward.
Understanding API & Webhooks
API & Webhooks is one of the foundational capabilities that separates professional scheduling from basic calendar tools. Build custom integrations with our REST API and real-time webhooks. Automate booking data flow to any internal system or third-party tool. When implemented well, it removes guesswork from the booking process and gives both you and your clients confidence that every appointment is handled correctly.
Without api & webhooks, scheduling often depends on manual coordination—back-and-forth emails, sticky notes, or spreadsheets that quickly fall out of sync. These workarounds create gaps: double-bookings slip through, availability windows go unadvertised, and administrative overhead grows with every new client. The result is lost revenue and a frustrating experience for everyone involved.
As part of SchedulingKit's broader workflow, api & webhooks connects directly to your calendar, notification, and client management systems. Changes propagate instantly, so your availability is always accurate, reminders go out on time, and your team stays aligned without any extra steps.

Best Practices
Get the most out of API & Webhooks with these practical tips
- 1
Use webhooks instead of polling the API for real-time booking updates — it's faster and uses fewer API calls.
- 2
Store webhook payloads idempotently using the event ID to handle potential duplicate deliveries safely.
- 3
Start with the sandbox environment to test your integration without affecting live booking data.
- 4
Implement pagination when fetching large datasets (bookings, contacts) to avoid timeout errors on high-volume accounts.
Frequently Asked Questions
Common questions about API & Webhooks
Is there a rate limit on the API?
Yes. Standard plans allow 100 requests per minute. Enterprise plans offer higher limits and dedicated endpoints for high-volume integrations.
What authentication method is used?
OAuth 2.0 for user-level access and API keys for server-to-server communication. Both are documented in our developer portal.
Are webhooks reliable?
Webhooks include automatic retries with exponential backoff. Failed deliveries are retried up to 5 times over 24 hours. You can also replay events from the dashboard.
Can I embed scheduling into my own product?
Yes. Our API and embeddable components let you build scheduling directly into your SaaS product, platform, or internal tool.
