## Discussion

Discussion The AppSupportedLanguages object provides metadata about a supported advertising market, including the country name, its ISO 3166-1 alpha-2 countryCode, and the language settings relevant for ad delivery. The adsSupportedLanguages field lists all languages available for ads in that market. The adsDefaultLanguages field lists the languages the system applies automatically when you don’t set explicit language targeting. The Query Supported App Languages endpoint returns this object, which you use to validate locale choices before setting them on creatives or ad groups. Example {   "name": "United States",   "countryCode": "US",   "adsSupportedLanguages": [     {       "language": "en",       "languageCode": "en-US"     },     {       "language": "es",       "languageCode": "es-US"     }   ],   "adsDefaultLanguages": [     {       "language": "en",       "languageCode": "en-US"     }   ] }
