SiteTran runs as a small Widget Code in your theme's frame.html, the template Shift4Shop wraps around every page of your store by default. Shift4Shop keeps rendering your store as usual, and SiteTran shows each shopper their language.
Sign up free and add your store. Copy your Widget Code from the Dropdown Style page. It adds the language dropdown to your storefront.
In your Shift4Shop Store Manager, open the Template Editor for your theme, click frame.html, and paste the Widget Code right before </body>. Then save.
Open your store and pick a language. SiteTran discovers your text as you browse, then you translate it with AI, your own translators, or both, and publish.
<script>var sitetran = {site_id: your_site_id};</script> <script src="//c.sitetran.com/widget/v3.js"></script> <div id="sitetran_translate_element"></div>
SiteTran gives you your own ready-to-paste code, with your site ID already in it. The div is where the language dropdown appears.
frame.html. If you'd rather not edit the template, paste the same three lines into Content › Header and Footer › Global Footer with WYSIWYG off. Use one place, not both.div sets where the dropdown appears. Keep the two script lines before </body> and move just the div into your header in frame.html, or position it with CSS.Shift4Shop's own language setting swaps your store's English for one other Latin-alphabet language. SiteTran lets one store offer every language your shoppers speak. Here's how it handles each part of a Shift4Shop store.
When Add to Cart Action is set to QuickCart, Shift4Shop shows a cart preview pop-up after the page has loaded. Quick View opens products from category pages the same way. SiteTran watches the page for new content and translates it as it appears.
Buttons, headings and instructions from Store Language, plus error messages from System Messages, are shown on your pages, so SiteTran translates them with everything else. Keep your Store Language in English and let SiteTran add the other languages.
Product names, descriptions, options, category pages, the blog and Site Content pages are translated as shoppers see them. You don't duplicate your catalog into a second store, and nothing is written back to Shift4Shop.
Shift4Shop says its store language supports only Latin-alphabet languages, one at a time. SiteTran applies translations in the shopper's browser, so one store can offer Spanish, French, Chinese and right-to-left Arabic side by side.
Labels such as "Subtotal", "Qty" and your free shipping message are translated, while your prices, shipping rates and tax rules keep working exactly as you set them in Shift4Shop.
Text that apps, review widgets and add-ons place on your pages is translated like the rest of your store, including content they load after the page opens.
Shift4Shop is built for US merchants, and a US store doesn't have to go overseas to find shoppers who prefer another language. Start with the languages your customers already speak.
The largest group you can reach without changing shipping zones, currency or tax setup. Use Translation Rules to set the tone you want, such as formal "usted", and the Glossary for gear terms you never want reworded.

Shift4Shop applies a Content Security Policy to checkout pages, which allowlists the scripts that run there. Open a ticket with Shift4Shop support and ask them to allow SiteTran's widget, which loads from c.sitetran.com and connects to www.sitetran.com.
Once it's allowed, single-page and 3-page checkout and the thank-you page are translated like the rest of your store.
Before you promote a language, browse a product page, open QuickCart and place a test order in that language, so every phrase on the way to checkout is discovered and approved.

Shift4Shop has no built-in language switcher. Here's what each route involves, from editing Store Language to running a second store.
Shift4Shop's Store Language, System Messages and email templates let you rewrite your store's built-in text in another language. That changes it for every shopper. To offer two languages natively, Shift4Shop's guidance is to run a separate store for each.
Rewriting Store Language or duplicating a store changes what's saved in Shift4Shop. Translation services and SiteTran translate the finished page, so one store serves every language and theme, app and product text is included.

Here's what's translated as soon as you install SiteTran, and how to give each language its own indexable URL when you're ready.
SiteTran translates more than visible text. When a shopper switches language, the page's metadata switches with it.

On a hosted Shift4Shop store, a proxy or edge worker in front of your domain calls the API and caches the result. We'll help you decide whether it's worth it for your markets.
