## Description

Add parameters to a location.
            
Some locations can be taxed differently depending on the properties of that location. In AvaTax, these tax-affecting properties are called "parameters".
            
A parameter added to a location will be used by default in tax calculation but will not show on the transaction line referencing the location.
            
A parameter specified on a transaction line will override a location parameter if they share the same parameter name.
            
To see available parameters for this location, call `/api/v2/definitions/parameters?$filter=attributeType eq Company`
            
Some parameters are only available for use if you have subscribed to specific AvaTax services. To see which parameters you are able to use, add the query parameter "$showSubscribed=true" to the parameter definition call above.
