Checkout : Customer Locale

[Blessy]

How does customer-locale value in checkout api response determined? is it from browser settings ?

[KarlOffenberger]

Good question.

Did a quick test using browsers in different locales but customer_locale was always "en" which is also what the store locale is. Thus, I suspect any orders placed via the store will extend that locale to the customer_locale.

@Shopify - clarification?

[KarlOffenberger]

Hmm, even after changing the stores language to "de", still customer_locale remains "en". Confusing.

We can send "order" customer_locale through the API or not? SHOPIFY said that param is "read-only" on API doc.
