# Bundled line items

To ensure that items aren't split into different pick jobs or routed to different facilities, items can be bundled. An item bundle is created by adding multiple items to a custom service and setting the `isBundled` flag to `true` within the order. The line items that should be bundled must be part of the `orderLineItems` array within the order.

```json
"customServices": [
  {
    "customServiceDefinition": {
      "isBundled": true
    },
    "articleItems": [
      {
        "tenantArticleRef": "32168",
        "quantity": 1
      }, {
        "tenantArticleRef": "31851",
        "quantity": 1
      }
    ],
    "customServiceItems": []
  }
]
```
