How to set the booking engine to French on your hotel website

Set the engine language for a 100% French experience

Key points:

  • The search engine language depends on the settings provided by your service provider (D-Edge, Reservit, Amenitiz, Mirai, etc.).
  • You can force the display in French via a link parameter or a configuration option.
  • A good translation of the search engine improves conversion rates and the consistency of the customer journey.
  • It is possible to add a language selector if you cater to an international clientele.

If your booking engine suddenly displays in English, it's usually due to a misconfigured language setting or an incomplete URL. Here's how to force it to display in French, providing a smooth and reassuring experience for your French-speaking visitors.

1. Check the language settings of the booking engine

Log in to your provider interface (D-Edge, Reservit, Amenitiz, Mirai, BookAssist, etc.) and then look for the Language / Language settings section. Make sure that:

  • French (FR) is indeed activated in the list of available languages.
  • French is set as the default language.
  • Custom texts (buttons, titles, confirmations) are translated.

💡 In some tools, you need to click “Save” or “Apply” for the language to actually be activated on the client side.

2. Check if the language is supported via the URL

Many search engines use a parameter in the URL to set the display language. For example:

  • D-Edge: https://secure.d-edge.com/?lang=fr

  • Reservit: https://reservation.reservit.com/?lang=fr

  • Amenitiz: https://booking.amenitiz.io/?lang=fr

💡 Quick fix: If your current link doesn't contain ?lang=fr, add it to the end of the URL in your "Book Now" button. 👉 Example: https://secure.d-edge.com/?hotel=XXXX&lang=fr

Next, republish your site and test the button again. The search engine will immediately display in French.

3. Correct the language via the embed code (if an embedded widget is used)

If your search engine is embedded directly into a page via HTML/iframe code, the language is sometimes defined in the script parameters. Example line in the code:

<iframe src="https://booking.amenitiz.io/?lang=fr" width="100%" height="800"></iframe>


💡 If you see lang=en, simply replace it with lang=fr and republish the site.

4. Check the default language of the browser or visitor

Some search engines automatically detect the language based on the user's browser. If your site is aimed at a French-speaking audience, you can:

  • Force the French language in the URL (?lang=fr) to bypass automatic detection.
  • Or offer a language selector (FR / EN / DE / ES) for international visitors.

💡 In this case, each “Book” button must point to the engine version corresponding to the selected language.

5. Publish and test the configuration

After changing the language setting, publish your site and then:

  • Click the “Book” button.
  • Check that the search engine interface (dates, buttons, booking steps) is in French.
  • Also try it on mobile and tablet.

If the engine still displays in English despite the changes, contact your service provider: it may be a server-side setting or an update that has not been propagated.

Conclusion

Yes, you can easily display your booking engine in French. Simply add the parameter ?lang=fr to your link or check the language settings in your provider area. An interface consistent with your website's language builds visitor trust and increases direct conversions.
