# Configuration

With the Tax Groups service plugin integrated into your app, Wix will retrieve the tax group you provide whenever it calls a catalog of products from your app. 
Follow these steps to add the service plugin and enable Wix to communicate with your app.

1. Go to [Extensions](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/about-extensions.md) in your app's dashboard.

1. Click **+ Create Extension** in the top right.

1. Find **Tax Groups Provider** and click **+ Create**.

1. 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|Base URI of the service plugin implementation. Since no endpoint is calling this path, it may be left blank.|
   | `defaultTaxGroup` |string|Name of the default tax group for this app. All products retrieved from this app will be categorized, by default, with this group name. The `id` for this tax group is the app's ID.|
   | `additionalTaxGroups` |object| Additional tax groups to be added to a site's tax settings when the app is installed. Each `additionalTaxGroup` must include an `id` and a `name`. |
   | `componentName` |string| A unique name for this component. This is an internal name that will only appear in the app dashboard.|

1. Click [**Test Your App**](https://dev.wix.com/docs/build-apps/launch-your-app/app-distribution/test-your-app/test-your-app-on-a-premium-site.md).
