# Transport

Details about the Transport parameter for VAT transactions, including its usage and default values.

**Element type:** Required

**Endpoints/models 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 allow users to specify who in the VAT transaction is responsible for handling the transportation of physical goods. This is done using the `Transport` parameter. This parameter defaults to `Seller` for physical goods transactions. For services transactions, this parameter has no default and isn't required.

You can specify transport in either the [TransactionParameterModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/TransactionParameterModel/) or the [TransactionLineParameterModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/TransactionLineParameterModel/).
