# Build the VIP experience

> Embed bespoke, exclusive VIP experiences into your app: a curated catalog, points and tiers, wallets, and a real-time concierge.

Expys delivers the ultimate VIP experience. We help you turn your highest-value
clients into loyalists by giving them bespoke, money-can't-buy moments they
remember for life: curated experiences, luxury travel, exclusive access, and a
real-time concierge - not the generic perks every competitor already offers.

These docs are for the teams who embed that experience into their own product.
Expys supplies the experiences, points, redemptions, member tiers, and concierge;
you bring the app your VIPs already use.

<Note>
  **VIP isn't a segment - it's where your business is won.** A small fraction of
  your users drives a disproportionate share of revenue and lifetime value. Expys
  is built to identify, delight, and grow exactly those clients.

Programs built on Expys drive proven revenue lift, top-tier NPS, and long,
repeated in-app engagement - while your hosts keep full ownership of the
relationship and Expys runs sourcing, booking, and on-site execution at scale.

## How you build it

Expys is a public REST `/v1` API with native SDKs for TypeScript, Swift, and
Kotlin. Your app embeds the member experience; your backend orchestrates points,
members, and analytics. Most teams have a live browse-and-redeem flow running
against the sandbox in an afternoon.

<CardGroup cols={2}>
  <Card title="Quickstart" icon="rocket" href="/quickstart">
    Install an SDK, mint a member token, and run your first browse-and-redeem
    flow in under five minutes.
  </Card>

  <Card title="Authentication" icon="key" href="/authentication">
    The two-token model: your backend mints short-lived member tokens with a
    secret Org-API-Key.
  </Card>

  <Card title="API reference" icon="terminal" href="/api-reference/introduction">
    Every endpoint, with schemas and a live "Try it" playground against the
    sandbox.
  </Card>

  <Card title="SDKs" icon="cubes" href="/sdks/overview">
    Install and usage notes for the TypeScript, Swift, and Kotlin SDKs.
  </Card>
</CardGroup>

## The two sides of the API

The surface splits in two, and knowing which credential goes where is the single
most important integration rule.

<CardGroup cols={2}>
  <Card title="Member mode" icon="mobile">
    Runs in your app with a short-lived **member token**. Browse experiences,
    redeem, read eligibility and wallet, and use the concierge.
  </Card>

  <Card title="Server mode" icon="server">
    Runs only on your backend with the secret **Org-API-Key**. Exchange tokens,
    mint points, manage members, read analytics, and register webhooks.
  </Card>
</CardGroup>

<Warning>
  The Org-API-Key is a secret. It belongs on your backend only - never ship it in
  an app, a mobile binary, or client-side code. See
  [Authentication](/authentication).
