# Sales location

**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 the location where a sale took place. This is done using the`SalesLocation` parameter. Optional values for this parameter are`onsite` and`offsite`.

```
"lines": [  {    "parameters":[      {        "name":"SalesLocation",        "value":"offsite"      }    ]  }]
```
