About the Wix eCommerce Shipping Rates Service Plugin

As a shipping provider, you can integrate your shipping rates service plugin (formerly SPI) with Wix to allow a merchant's stores or businesses to request and use your shipping services on their Wix sites. The shipping rates are then displayed on the site's cart and checkout pages.

The integration is done via an app in the Wix App Market (created in the Wix Studio workspace), and the Wix Shipping Rates service plugin.

Using the service plugin, you can design your app to:

  • Provide shipping estimates, including fees and times.
  • Provide shipping rates using your own custom logic.
  • Provide services for delivery and pickup.

Terminology

  • Get Shipping Rates: Wix calls this service plugin endpoint to retrieve the shipping rates you provide.
  • Merchant: Business that offers products on their Wix site to customers.
  • Wix site owner: The person managing the merchant's Wix site.
  • Shipping Rates Provider: A 3rd-party app that implements custom logic to calculate shipping rates.
