## Install the middleware

Add the Express adapter and Zod:

<Tabs>
  <Tab title="npm">
    ```bash Terminal theme={"system"}
    npm install zod @getruba/express
    ```
  </Tab>

  <Tab title="yarn">
    ```bash Terminal theme={"system"}
    yarn add zod @getruba/express
    ```
  </Tab>

  <Tab title="pnpm">
    ```bash Terminal theme={"system"}
    pnpm add zod @getruba/express
    ```
  </Tab>

  <Tab title="bun">
    ```bash Terminal theme={"system"}
    bun add zod @getruba/express
    ```
  </Tab>
</Tabs>

## Create the checkout entry route

Mount `Checkout` on a `GET` route. The middleware resolves the checkout and sends the buyer to it.

```typescript theme={"system"}
import express from "express";
import { Checkout } from "@getruba/express";

const app = express();

app.get(
  "/checkout",
  Checkout({
    accessToken: "xxx", // Or set an environment variable to RUBA_ACCESS_TOKEN
    successUrl: process.env.SUCCESS_URL,
    returnUrl: "https://myapp.com", // An optional URL which renders a back-button in the Checkout
    server: "sandbox", // Use sandbox if you're testing Ruba - omit the parameter or pass 'production' otherwise
    theme: "dark", // Enforces the theme - System-preferred theme will be set if left omitted
  })
);
```

### Inputs accepted by the checkout route

| Query value          | Use                                                  |
| -------------------- | ---------------------------------------------------- |
| `products`           | One product ID or the product selection for checkout |
| `customerId`         | Optional Ruba customer identity                      |
| `customerExternalId` | Optional identity from your own application          |
| `customerEmail`      | Optional buyer email prefill                         |
| `customerName`       | Optional buyer name prefill                          |
| `metadata`           | Optional URL-encoded JSON metadata                   |

For example, `?products=123&customerExternalId=user_42` selects a product and ties the session to your application identity.

## Create the account-management route

Return the Ruba customer ID for the current application user. The middleware then opens that customer's portal.

```typescript theme={"system"}
import express from "express";
import { CustomerPortal } from "@getruba/express";

const app = express();

app.get(
  "/portal",
  CustomerPortal({
    accessToken: "xxx", // Or set an environment variable to RUBA_ACCESS_TOKEN
    getCustomerId: (event) => "", // Function to resolve a Ruba Customer ID
    returnUrl: "https://myapp.com", // An optional URL which renders a back-button in the Customer Portal
    server: "sandbox", // Use sandbox if you're testing Ruba - omit the parameter or pass 'production' otherwise
  })
);
```

## Receive signed events

Mount `Webhooks` after JSON parsing. It validates the Ruba signature before invoking your callback.

```typescript theme={"system"}
import express from 'express'
import { Webhooks } from "@getruba/express";

const app = express()

app
.use(express.json())
.post('/ruba/webhooks', Webhooks({
  webhookSecret: process.env.RUBA_WEBHOOK_SECRET!,
  onPayload: async (payload) => /** Handle payload */,
}))
```

### Choose callback granularity

Use `onPayload` as a catch-all or register callbacks around the domain your application owns:

| Domain             | Available callbacks                                                                                                                                     |
| ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Checkout           | `onCheckoutCreated`, `onCheckoutUpdated`                                                                                                                |
| Orders and refunds | `onOrderCreated`, `onOrderPaid`, `onOrderRefunded`, `onRefundCreated`, `onRefundUpdated`                                                                |
| Subscriptions      | `onSubscriptionCreated`, `onSubscriptionUpdated`, `onSubscriptionActive`, `onSubscriptionCanceled`, `onSubscriptionRevoked`, `onSubscriptionUncanceled` |
| Catalog            | `onProductCreated`, `onProductUpdated`, `onBenefitCreated`, `onBenefitUpdated`                                                                          |
| Entitlements       | `onBenefitGrantCreated`, `onBenefitGrantUpdated`, `onBenefitGrantRevoked`                                                                               |
| Customers          | `onCustomerCreated`, `onCustomerUpdated`, `onCustomerDeleted`, `onCustomerStateChanged`                                                                 |
| Organization       | `onOrganizationUpdated`                                                                                                                                 |
