# GraphQL Admin API: Update to `returnLineItems` connection

Starting in version `2024-07`, the [`Return.returnLineItems` connection](https://shopify.dev/docs/api/admin-graphql/2024-04/objects/Return#connection-returnlineitems) becomes an interface type. This change is designed to accommodate more diverse return item types in the future, which will increase your flexibility in handling returns.

To maintain compatibility with existing implementations, adjust their queries to use an inline fragment, as shown in the example below. This adjustment ensures that queries will continue to function correctly with the new interface type.

```graphql
returnLineItems(first: 30) {
  edges {
    cursor
    node {
      ... on ReturnLineItem {
        id
        ...ReturnLineItemAttributes
      }
    }
  }
}
```
