Configuration

With the Tax Calculation service plugin integrated into your app, Wix will call your app with Calculate Tax whenever tax needs to be recalculated on a site. For example, when line items are updated in a cart or checkout. Follow these steps to add the service plugin and enable Wix to communicate with your app.

1. Go to the Extensions tab in the Wix Dev Center.

2. Click + Create Extension in the top right.

3. Find Tax Calculation Provider and click + Create.

4. Use the JSON editor to create the extension's configuration file. Configure the parameters by referencing the table below or the Documentation section to the right of the editor. For each parameter, add the parameter name and value in the JSON editor.

   Name	Type	Description
   deploymentUri	string	Required. Base URI where the endpoints are called. Wix appends the endpoint path to the base URI. For example, to call the Calculate Tax endpoint at https://my-tax-calc.com/v1/calculateTax, the base URI you provide here is https://my-tax-calc.com/.
   calculatorDisplayName	string	Display name of the tax calculator.
   unsupportedCountries	array	List of countries, in ISO-3166 alpha-1 format, that the calculator does not support.
