locale

locale is composed of language identifier and region identifier, connected by \"_\" that specifies the language in which the response will be returned. You can find a link to the complete list of locales along with the Point of Sale List in Supported Points of Sale. Note that even though the Listings API supports localization for all locales listed in the list, all locales are not valid for all Points of Sale. For example, Ecom US POS supports en_US, es_MX and zh_CN. For Ecom US POS, the Listings API will respond with content in Spanish for requests with either locale=es_MX or es_US. However, only the deeplinks for locale=es_MX should work properly and switch the website to Spanish, while the ones for locale=es_US will be fallen back to English. If not specified in the query, the native language for that POS will be returned. And if more than one language is supported, the response will be returned in the first language depending on the language setting of the POS.
