# Request Context

> Read-only globals available inside backend scripts: request data, customer info, and visitor details.

These globals are injected automatically into every backend script execution. They are **read-only** — you cannot modify them directly.

## `request`

Information about the current HTTP request.

```javascript theme={null}
request.query          // { foo: 'bar', utm_source: 'google' }
request.headers        // see below
request.method         // 'GET' or 'POST'
request.body           // parsed JSON body (POST only, null for GET, max 64 KB)
request.ip             // IPv4 address, e.g. '1.2.3.4'
request.ip6            // IPv6 address (if available)
request.path           // '/my-page'
request.cookies        // { cookie_name: 'value' }
request.is_mobile      // true/false
request.is_tablet      // true/false
```

### `request.body`

When a page receives a `POST` request with a JSON body, it is parsed and available as `request.body`. Pages accept both GET and POST requests — the same backend script runs for both. Use `request.method` to distinguish.

```javascript theme={null}
if (request.method === 'POST' && request.body) {
  var data = request.body;
  console.log('Received:', data.name);
}
```

<Note>
  The body is capped at **64 KB**. Larger payloads are silently dropped (`request.body` will be `null`). Only JSON content types are parsed — form-urlencoded and multipart are not supported.
</Note>

### `request.headers`

A subset of request headers is exposed:

| Key               | Description                      |
| ----------------- | -------------------------------- |
| `user-agent`      | Browser/device user-agent string |
| `referer`         | Referring URL                    |
| `accept-language` | Visitor's language preferences   |
| `host`            | Domain the request was made to   |

<Warning>
  Full request headers are not exposed to prevent leaking internal infrastructure details (e.g. proxy headers, auth tokens).
</Warning>

## `customer`

The current customer object from the session, or `null` if no customer is set. Populated after checkout or check-order login.

```javascript theme={null}
customer.name
customer.email
customer.first_name
customer.last_name
customer.phone
customer.order_id
customer.order_ids           // array of order objects
customer.order_item
customer.order_item_name
customer.conversion_code
customer.payment_provider
customer.billing_first_name
customer.billing_last_name
customer.billing_address
customer.billing_city
customer.billing_state
customer.billing_zip
customer.billing_country
customer.shipping_first_name
customer.shipping_last_name
customer.shipping_address
customer.shipping_city
customer.shipping_state
customer.shipping_zip
customer.shipping_country
```

## `is_customer`

Boolean. `true` if the visitor has an active customer session (completed a purchase or logged in via check-order).

```javascript theme={null}
if (!is_customer) {
  redirect('/sales-page');
}
```
