For Wix integration, we do not support calculated shipping rates at checkout. You can associate the Gelato products with your existing shipping setup or create new shipping regions by referring to the Gelato flat rates shipping guide. For more information, please visit the article on how to set up shipping in the Wix Help Center.
You can set up shipping regions based on the countries you wish to sell to and our article What countries are included in each geographical area used for flat shipping.
You can set up product groups and link your store products to the relevant groups.
You can then set prices for each geographical region and product type with reference to the flat rate shipping fees in our product catalog.
