Parameters
Name	Description
data	array Optional. Data for populating the Message object.
↳ expire_time	Google\Protobuf\Timestamp The timestamp when this product becomes unavailable for SearchService.Search. Note that this is only applicable to Type.PRIMARY and Type.COLLECTION, and ignored for Type.VARIANT. In general, we suggest the users to delete the stale products explicitly, instead of using this field to determine staleness. If it is set, the Product is not available for SearchService.Search after expire_time. However, the product can still be retrieved by ProductService.GetProduct and ProductService.ListProducts. expire_time must be later than available_time and publish_time, otherwise an INVALID_ARGUMENT error is thrown. Corresponding properties: Google Merchant Center property expiration_date.
↳ ttl	Google\Protobuf\Duration Input only. The TTL (time to live) of the product. Note that this is only applicable to Type.PRIMARY and Type.COLLECTION, and ignored for Type.VARIANT. In general, we suggest the users to delete the stale products explicitly, instead of using this field to determine staleness. If it is set, it must be a non-negative value, and expire_time is set as current timestamp plus ttl. The derived expire_time is returned in the output and ttl is left blank when retrieving the Product. If it is set, the product is not available for SearchService.Search after current timestamp plus ttl. However, the product can still be retrieved by ProductService.GetProduct and ProductService.ListProducts.
↳ name	string Immutable. Full resource name of the product, such as projects/*/locations/global/catalogs/default_catalog/branches/default_branch/products/product_id.
↳ id	string Immutable. Product identifier, which is the final component of name. For example, this field is "id_1", if name is projects/*/locations/global/catalogs/default_catalog/branches/default_branch/products/id_1. This field must be a UTF-8 encoded string with a length limit of 128 characters. Otherwise, an INVALID_ARGUMENT error is returned. Corresponding properties: Google Merchant Center property id. Schema.org property Product.sku.
↳ type	int Immutable. The type of the product. Default to Catalog.product_level_config.ingestion_product_type if unset.
↳ primary_product_id	string Variant group identifier. Must be an id, with the same parent branch with this product. Otherwise, an error is thrown. For Type.PRIMARY Products, this field can only be empty or set to the same value as id. For VARIANT Products, this field cannot be empty. A maximum of 2,000 products are allowed to share the same Type.PRIMARY Product. Otherwise, an INVALID_ARGUMENT error is returned. Corresponding properties: Google Merchant Center property item_group_id. Schema.org property Product.inProductGroupWithID.
↳ collection_member_ids	array The id of the collection members when type is Type.COLLECTION. Non-existent product ids are allowed. The type of the members must be either Type.PRIMARY or Type.VARIANT otherwise an INVALID_ARGUMENT error is thrown. Should not set it for other types. A maximum of 1000 values are allowed. Otherwise, an INVALID_ARGUMENT error is return.
↳ gtin	string The Global Trade Item Number (GTIN) of the product. This field must be a UTF-8 encoded string with a length limit of 128 characters. Otherwise, an INVALID_ARGUMENT error is returned. This field must be a Unigram. Otherwise, an INVALID_ARGUMENT error is returned. Corresponding properties: Google Merchant Center property gtin. Schema.org property Product.isbn, Product.gtin8, Product.gtin12, Product.gtin13, or Product.gtin14. If the value is not a valid GTIN, an INVALID_ARGUMENT error is returned.
↳ categories	array Product categories. This field is repeated for supporting one product belonging to several parallel categories. Strongly recommended using the full path for better search / recommendation quality. To represent full path of category, use '>' sign to separate different hierarchies. If '>' is part of the category name, replace it with other character(s). For example, if a shoes product belongs to both ["Shoes & Accessories" -> "Shoes"] and ["Sports & Fitness" -> "Athletic Clothing" -> "Shoes"], it could be represented as: "categories": [ "Shoes & Accessories > Shoes", "Sports & Fitness > Athletic Clothing > Shoes" ] Must be set for Type.PRIMARY Product otherwise an INVALID_ARGUMENT error is returned.

↳ language_code	string Language of the title/description and other string attributes. Use language tags defined by BCP 47. For product prediction, this field is ignored and the model automatically detects the text language. The Product can include text in different languages, but duplicating Products to provide text in multiple languages can result in degraded model performance. For product search this field is in use. It defaults to "en-US" if unset.
↳ attributes	array|Google\Protobuf\Internal\MapField Highly encouraged. Extra product attributes to be included. For example, for products, this could include the store name, vendor, style, color, etc. These are very strong signals for recommendation model, thus we highly recommend providing the attributes here. Features that can take on one of a limited number of possible values. Two types of features can be set are: Textual features. some examples would be the brand/maker of a product, or country of a customer. Numerical features. Some examples would be the height/weight of a product, or age of a customer. For example: { "vendor": {"text": ["vendor123", "vendor456"]}, "lengths_cm": {"numbers":[2.3, 15.4]}, "heights_cm": {"numbers":[8.1, 6.4]} }. This field needs to pass all below criteria, otherwise an INVALID_ARGUMENT error is returned: * Max entries count: 200. * The key must be a UTF-8 encoded string with a length limit of 128 characters. * For indexable attribute, the key must match the pattern: [a-zA-Z0-9][a-zA-Z0-9_]*.

↳ audience	Google\Cloud\Retail\V2\Audience The target group associated with a given audience (e.g. male, veterans, car owners, musicians, etc.) of the product.
↳ color_info	Google\Cloud\Retail\V2\ColorInfo The color of the product. Corresponding properties: Google Merchant Center property color. Schema.org property Product.color.
↳ sizes	array The size of the product. To represent different size systems or size types, consider using this format: [[[size_system:]size_type:]size_value]. For example, in "US:MENS:M", "US" represents size system; "MENS" represents size type; "M" represents size value. In "GIRLS:27", size system is empty; "GIRLS" represents size type; "27" represents size value. In "32 inches", both size system and size type are empty, while size value is "32 inches".

↳ publish_time	Google\Protobuf\Timestamp The timestamp when the product is published by the retailer for the first time, which indicates the freshness of the products. Note that this field is different from available_time, given it purely describes product freshness regardless of when it is available on search and recommendation.
↳ retrievable_fields	Google\Protobuf\FieldMask Indicates which fields in the Products are returned in SearchResponse. Supported fields for all types: * audience * availability * brands * color_info * conditions * gtin * materials * name * patterns * price_info * rating * sizes * title * uri Supported fields only for Type.PRIMARY and Type.COLLECTION: * categories * description * images Supported fields only for Type.VARIANT: * Only the first image in images To mark attributes as retrievable, include paths of the form "attributes.key" where "key" is the key of a custom attribute, as specified in attributes. For Type.PRIMARY and Type.COLLECTION, the following fields are always returned in SearchResponse by default: * name For Type.VARIANT, the following fields are always returned in by default: * name * color_info The maximum number of paths is 30. Otherwise, an INVALID_ARGUMENT error is returned. Note: Returning more fields in SearchResponse can increase response payload size and serving latency. This field is deprecated.
