# Seller classification

**Element type: Required**

**Endpoints used:** [TransactionParameterModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/TransactionParameterModel/), [TransactionLineParameterModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/TransactionLineParameterModel/)

Your integration must provide a way for users to specify whether a transaction is taking place within a state or between states. This is done using the`SellerClassification` parameter. For beverage alcohol transactions, the available values are:

-   `InStateDirectShipper`
-   `OutOfStateDirectShipper`

```
"lines": [  {    "parameters":[      {        "name":"SellerClassification",        "value":"OutOfStateDirectShipper"      }    ]  }]
```
