# What is SeatLayer?

SeatLayer is reserved-seating infrastructure for products that need buyers to choose a real seat, table, booth, or general-admission place. You own the customer, checkout, and payment. SeatLayer owns venue geometry and live inventory.

> **The integration contract**
>
> The **browser holds** inventory temporarily. **Your server books** after it has inspected the hold and completed your payment or order logic.

## Two objects power everything

- **Chart** — The reusable venue document: rows, tables, booths, GA areas, sections, accessibility metadata, and pricing categories.
- **Event** — A published chart placed on sale with independent, realtime seat inventory. Reuse one chart for many performances.

## Seat lifecycle

| Status | Meaning | Who changes it |
|---|---|---|
| `free` | Available to select | Expiry, release, or operator |
| `held` | Reserved for a short checkout window | Buyer SDK |
| `booked` | Permanently sold | Your server |
| `not_for_sale` | Removed from sale | Organizer or operator |

The picker receives inventory updates in realtime, so buyers see a seat disappear before they can select stale inventory. A successful booking is all-or-nothing: conflicts return without partially booking the request.

## What stays in your product

- Buyer identity, orders, payments, refunds, and tax logic.
- The final decision to confirm a booking.
- Your own checkout UI and business rules.

## What SeatLayer provides

- A white-label Designer for authoring complex venues.
- Buyer SDKs for script tag, JavaScript, React, React Native, iOS, Android, and Flutter.
- Realtime holds and inventory synchronization.
- Server APIs, signed webhooks, an embeddable control room, and reporting.

- **Build the full loop** — Continue to the [Quickstart](/start/quickstart) to create a test event, embed the picker, and confirm a booking.
- **Inspect the server contract** — Jump to the [booking endpoint](/server-api/booking) for request fields, responses, and conflict handling.
