Estos son los diferentes tipos de ID de producto en la Content API for Shopping:
ID de la oferta
Un offerId es una string que un comercio le asigna a un producto. Este ID representa un producto individual.
offerId es único para el conjunto de ofertas en la base de datos de Merchant Center y, por lo general, es un número secuencial numérico.
offerId puede ser un número de SKU interno que un comerciante asigna al producto.
ID de REST
Un ID de REST es el identificador único de un producto que Google asigna.
El ID de REST es productId para las llamadas a la API de REST.
Los ID de REST se agregan con el formato online:en:label:1111111111. El ID de REST consta de las siguientes 4 partes, separadas por dos puntos:
Canal ("en línea" o "local")
Idioma del contenido (con la designación de dos letras, por ejemplo, en o fr)
Etiqueta del feed (puede ser el código de dos letras del país de destino del feed, por ejemplo, US o FR)
ID de la oferta
Debes combinar esto como channel:contentLanguage:feedLabel:offerId, por ejemplo, online:en:US:1111111111.
ID de vendedor externo (mercados)
Marketplaces debe asignar un external_seller_id a las ofertas subidas a una cuenta de varios vendedores. Este campo representa a un vendedor individual.
Los valores external_seller_id distinguen entre mayúsculas y minúsculas, y deben cumplir con los siguientes criterios:
1 a 50 caracteres
Solo los caracteres ASCII alfanuméricos y el guion bajo (_), el guion (-), el punto (.) y la virgulilla (~)
En la siguiente tabla, se resumen algunos de los ID que se pueden asociar con un producto:
