Earlier this year, we added support for managing price extensions to the AdWords API. This included the addition of PriceFeedItem to extension setting services in v201607, and placeholder type ID 35 to feed services in all versions of the AdWords API. At that time, both supported only English price extension type, price qualifiers and price units.

Starting today, we are rolling out support for additional languages in price extension types, price qualifiers and price units. Price extensions’ headers and descriptions will be reviewed in the context of the specified language, and those written in languages other than the specified one will be disapproved.

How to use this feature

• Extension setting services: Set language to the locale of your desired language and use priceExtensionType, priceQualifier and priceUnit in the same way as before.
• Feed services: Check out the translated price extension types, price qualifiers and price units, and ensure that you use the translated price feed type (placeholder field ID 1), price qualifier (placeholder field ID 2) and price units (placeholder field ID 103, 203, …, 803) that match with the language code you specify as placeholder field ID 4. For all available placeholder fields for price feeds, refer to the feed placeholders page.

Note: All PriceTableRow entries must have the same currencyCode or you will get the ExtensionSettingError.INCONSISTENT_CURRENCY_CODES error.
