`pnpm install @spaire/tanstack-start zod`

## Checkout

Create a Checkout handler which takes care of redirections.

```typescript
// routes/api/checkout.ts
import { Checkout } from "@spaire/tanstack-start";
import { createAPIFileRoute } from "@tanstack/react-start/api";

export const APIRoute = createAPIFileRoute("/api/checkout")({
  GET: Checkout({
    accessToken: process.env.SPAIRE_ACCESS_TOKEN,
    successUrl: process.env.SUCCESS_URL,
    returnUrl: "https://myapp.com", // Optional Return URL, which renders a Back-button in the Checkout
    server: "sandbox", // Use sandbox if you're testing Spaire - omit the parameter or pass 'production' otherwise
    theme: "dark" // Enforces the theme - System-preferred theme will be set if left omitted
  }),
});
```

### Query Params

Pass query params to this route.

- products `?products=123`
- customerId (optional) `?products=123&customerId=xxx`
- customerExternalId (optional) `?products=123&customerExternalId=xxx`
- customerEmail (optional) `?products=123&customerEmail=janedoe@gmail.com`
- customerName (optional) `?products=123&customerName=Jane`
- seats (optional) `?products=123&seats=5` - Number of seats for seat-based products
- metadata (optional) `URL-Encoded JSON string`

## Customer Portal

Create a customer portal where your customer can view orders and subscriptions.

```typescript
// routes/api/portal.ts
import { CustomerPortal } from "@spaire/tanstack-start";
import { createAPIFileRoute } from "@tanstack/react-start/api";
import { getSupabaseServerClient } from "~/servers/supabase-server";

export const APIRoute = createAPIFileRoute("/api/portal")({
  GET: CustomerPortal({
    accessToken: process.env.SPAIRE_ACCESS_TOKEN,
    getCustomerId: async (request: Request) => "", // Fuction to resolve a Spaire Customer ID
    returnUrl: "https://myapp.com", // Optional Return URL, which renders a Back-button in the Customer Portal
    server: "sandbox", // Use sandbox if you're testing Spaire - omit the parameter or pass 'production' otherwise
  }),
});
```

## Webhooks

A simple utility which resolves incoming webhook payloads by signing the webhook secret properly.

```typescript
// api/webhook/spaire.ts
import { Webhooks } from "@spaire/tanstack-start";
import { createAPIFileRoute } from "@tanstack/react-start/api";

export const APIRoute = createAPIFileRoute("/api/webhook/spaire")({
  POST: Webhooks({
    webhookSecret: process.env.SPAIRE_WEBHOOK_SECRET!,
    onPayload: async (payload) => {
      // Handle the payload
      // No need to return an acknowledge response
    },
  }),
});
```

#### Payload Handlers

The Webhook handler also supports granular handlers for easy integration.
