LangShop supports Shopify translation API that sets language limits for multilingual stores on the platform. According to Shopify rules, you can add five more languages to your online store.
If you are a Shopify Plus merchant, you can add 20 languages. You will have 21 languages in total: your store language and 20 additional ones. You can add more than 20 languages, but only the first 20 will be published. If you want to publish another language, you need to unpublish one of the target languages.
