Stripe recognizes the default language of your ecommerce and uses the same language to show the payment form to customers.
If your site’s language is not among those supported by Stripe, then Stripe will be set to English.
In any case, it is possible to customize the text elements of the form.
To do this, you can go to the back-office Prestashop menu:
Choose the tab International > Translation
- Type of translation > Translation of installed modules
- Select your module > Stripe payment module
- Select your language > select the language in use on your site
- Click on Modify button
At this point you will see the list of all the elements that you can customize.
To find a specific item, use the search function inside your browser that you can normally activate using the (CTRL + F) key combination.
