HI Hanzo, I'm creating a Subscription on my Java Backend but every invoices generated are in English, I would like to change by end customer's preferred language (most of the time French)

Hello 👋
I think the locale is set by the setting on customer object
Have you tried updating the customer's preferred language?
https://stripe.com/docs/api/customers/update#update_customer-preferred_locales

I tried preferredLocale but no effect:

                CustomerCreateParams.builder()
                    .setEmail(signupUser.getEmail())
                    .setName(signupUser.getNom())
                    .addPreferredLocale(signupUser.getLanguage())
                    .setShipping(
                    CustomerCreateParams.Shipping.builder()
                        .setAddress(
                        CustomerCreateParams.Shipping.Address.builder()
                            .setCity(signupUser.getVille())
                            .setCountry(signupUser.getLanguage())
                            .setLine1(signupUser.getAdresse())
                            .setPostalCode(signupUser.getCp())
                            .setState("")
                            .build()
                        )
                        .setName(createdSubscription.getNom())
                        .build()
                    )
                    .setAddress(
                CustomerCreateParams.Address.builder()
                        .setCity(signupUser.getVille())
                        .setCountry(signupUser.getLanguage())
                        .setLine1(signupUser.getAdresse())
                        .setPostalCode(signupUser.getCp())
                        .setState("")
                        .build()
                    )
                    .build();

                Customer customer = Customer.create(params);```

but I do not see any way to set the Preferred Language, only the locale

[mystic vessel]

Updating the customer after the invoice has been generated won't retroactivelly update the invoice.
The changes will apply when the next invoice is generated.

Can you create a new invoice for the customer after updating the locale?

[spark turret]

but since the beginning the Locale is set to FR

and every invoices are in EN

[mystic vessel]

Can you share an example customer ID and the invoice?

[spark turret]

yes

I can change the Language of the Customer on the Dashboard but I would need to do it programmatically

in the doc: https://stripe.com/docs/invoicing/customer?locale=fr-CA&dashboard-or-api=api it is explained how to change it on the Dashboard

but though API, they mention preferred_locales but I do not see how to do it

https://stripe.com/docs/api/customers/object#customer_object-preferred_locales

[mystic vessel]

You'd just send an array of locales by preference to the update customer endpoint
https://stripe.com/docs/api/customers/update#update_customer-preferred_locales

OR you can also just pass it in when you create a customer
https://stripe.com/docs/api/customers/create#create_customer-preferred_locales

[spark turret]

sorry preferred locale is set correctly

                CustomerCreateParams.builder()
                    .setEmail(signupUser.getEmail())
                    .setName(signupUser.getNom())
                    .addPreferredLocale(signupUser.getLanguage())```

but there is no effect on the language

[mystic vessel]

Can you share an example request ID of when you create the customer?

[spark turret]

hum...it seems it shall be fr but i set FR may be this is the reason why it doesn't work

[mystic vessel]

Try changing it

[spark turret]

I did

and I was right

language shall be set in lowercase

[mystic vessel]

Great, did that create the invoice in preferred locale too?

[spark turret]

yes

😉

finally !

that was a simple one !
