# API and Building Apps

Sesami provides public API access and an app platform, giving developers the tools to extend Sesami and build custom integrations.

## API Access

Sesami's API lets you integrate Sesami into your own systems and workflows:

* **Automate tasks** — sync booking data with external systems
* **Build custom integrations** — connect Sesami with your CRM, ERP, or internal tools
* **Sync data** — pull appointment, service, and resource data into your own platforms
* **Create custom booking flows** — build tailored experiences using the Sesami SDK

All Sesami plans include **API and SDK access**.

## Sesami Apps

Sesami Apps let you build embedded experiences that run directly inside the Sesami Admin Portal and within the booking flow.

### What Sesami Apps Can Do

* **Admin Portal integration** — add a settings/configuration page where merchants manage your app
* **Booking flow extensions** — deploy functionality at specific points in the customer booking experience (e.g., collecting data during booking, displaying info in appointment details)
* **Enhance workflows** — extend Sesami's capabilities with custom features

### Example: Sesami Forms App

The [Sesami Forms App](/apps-integrations/sesami-forms-app.md) is a great example — it embeds an intake form directly in the booking flow, collecting customer information during the booking process.

### Public and Private Apps

* **Private apps** — built for a specific shop or internal use
* **Public apps** — shareable via the Sesami App Store
