# Passing guest preferred language to Guesty

You can send each guest's preferred language to Guesty with their booking. This is supported as of HomeRunner Gravity Forms add-on version 0.4.0.

1. Update the HomeRunner Gravity Forms add-on to version 0.4.0 or later.
2. On the checkout form, add a hidden field and set its parameter name to **language**. This uses the same dynamic-population mechanism as **quote_id**. A visible field labeled "Language" or "Preferred Language" also works.
3. Populate the field with the current language code, a two-letter ISO 639-1 code such as nl, en, de, or fr. Longer codes like nl-NL are accepted and trimmed to the two-letter code automatically.
4. Run a test booking.

**What you see in Guesty.** The value appears on the Guesty guest profile as the preferred language. Guesty's automated message flows key off this value.

**Good to know.** The field is optional, and bookings without it behave exactly as before. Non-language values are ignored rather than causing errors.

**For developers.** The **homegf_guest_language** filter can supply the value in code instead of a form field.
