| Args: |
| placement: string, Required. Full resource name of the format: {name=projects/*/locations/global/catalogs/default_catalog/placements/*} The ID of the Recommendations AI placement. Before you can request predictions from your model, you must create at least one placement for it. For more information, see [Managing placements](https://cloud.google.com/retail/recommendations-ai/docs/manage-placements). The full list of available placements can be seen at https://console.cloud.google.com/recommendation/catalogs/default_catalog/placements (required) |
| body: object, The request body. |
| The object takes the form of: |
| |
| { # Request message for Predict method. |
| "filter": "A String", # Filter for restricting prediction results with a length limit of 5,000 characters. Accepts values for tags and the `filterOutOfStockItems` flag. * Tag expressions. Restricts predictions to products that match all of the specified tags. Boolean operators `OR` and `NOT` are supported if the expression is enclosed in parentheses, and must be separated from the tag values by a space. `-"tagA"` is also supported and is equivalent to `NOT "tagA"`. Tag values must be double quoted UTF-8 encoded strings with a size limit of 1,000 characters. Note: "Recently viewed" models don't support tag filtering at the moment. * filterOutOfStockItems. Restricts predictions to products that do not have a stockState value of OUT_OF_STOCK. Examples: * tag=("Red" OR "Blue") tag="New-Arrival" tag=(NOT "promotional") * filterOutOfStockItems tag=(-"promotional") * filterOutOfStockItems If your filter blocks all prediction results, nothing will be returned. If you want generic (unfiltered) popular products to be returned instead, set `strictFiltering` to false in `PredictRequest.params`. |
| "labels": { # The labels applied to a resource must meet the following requirements: * Each resource can have multiple labels, up to a maximum of 64. * Each label must be a key-value pair. * Keys have a minimum length of 1 character and a maximum length of 63 characters, and cannot be empty. Values can be empty, and have a maximum length of 63 characters. * Keys and values can contain only lowercase letters, numeric characters, underscores, and dashes. All characters must use UTF-8 encoding, and international characters are allowed. * The key portion of a label must be unique. However, you can use the same key with multiple resources. * Keys must start with a lowercase letter or international character. See [Google Cloud Document](https://cloud.google.com/resource-manager/docs/creating-managing-labels#requirements) for more details. |
| "a_key": "A String", |
| }, |
| "pageSize": 42, # Maximum number of results to return per page. Set this property to the number of prediction results needed. If zero, the service will choose a reasonable default. The maximum allowed value is 100. Values above 100 will be coerced to 100. |
| "pageToken": "A String", # The previous PredictResponse.next_page_token. |
| "params": { # Additional domain specific parameters for the predictions. Allowed values: * `returnProduct`: Boolean. If set to true, the associated product object will be returned in the `results.metadata` field in the prediction response. * `returnScore`: Boolean. If set to true, the prediction 'score' corresponding to each returned product will be set in the `results.metadata` field in the prediction response. The given 'score' indicates the probability of an product being clicked/purchased given the user's context and history. * `strictFiltering`: Boolean. True by default. If set to false, the service will return generic (unfiltered) popular products instead of empty if your filter blocks all prediction results. |
| "a_key": "", |

| "userEvent": { # UserEvent captures all metadata information Retail API needs to know about how end users interact with customers' website. # Required. Context about the user, what they are looking at and what action they took to trigger the predict request. Note that this user event detail won't be ingested to userEvent logs. Thus, a separate userEvent write request is required for event logging. |
| "attributes": { # Extra user event features to include in the recommendation model. The key must be a UTF-8 encoded string with a length limit of 5,000 characters. Otherwise, an INVALID_ARGUMENT error is returned. For product recommendation, an example of extra user information is traffic_channel, i.e. how user arrives at the site. Users can arrive at the site by coming to the site directly, or coming through Google search, and etc. |
| "a_key": { # A custom attribute that is not explicitly modeled in Product. |
| "numbers": [ # The numerical values of this custom attribute. For example, `[2.3, 15.4]` when the key is "lengths_cm". At most 400 values are allowed.Otherwise, an INVALID_ARGUMENT error is returned. Exactly one of text or numbers should be set. Otherwise, an INVALID_ARGUMENT error is returned. |
| 3.14, |

| "attributionToken": "A String", # Highly recommended for user events that are the result of PredictionService.Predict. This field enables accurate attribution of recommendation model performance. The value must be a valid PredictResponse.attribution_token for user events that are the result of PredictionService.Predict. This token enables us to accurately attribute page view or purchase back to the event and the particular predict response containing this clicked/purchased product. If user clicks on product K in the recommendation results, pass PredictResponse.attribution_token as a URL parameter to product K's page. When recording events on product K's page, log the PredictResponse.attribution_token to this field. |
| "cartId": "A String", # The id or name of the associated shopping cart. This id is used to associate multiple items added or present in the cart before purchase. This can only be set for `add-to-cart`, `purchase-complete`, or `shopping-cart-page-view` events. |

For instance, a special sale page may have the category hierarchy: "pageCategories" : ["Sales > 2017 Black Friday Deals"]. Required for `category-page-view` events. At least one of search_query or page_categories is required for `search` events. Other event types should not set this field. Otherwise, an INVALID_ARGUMENT error is returned. |
| "A String", |
| ], |
| "pageViewId": "A String", # A unique id of a web page view. This should be kept the same for all user events triggered from the same pageview. For example, an item detail page view could trigger multiple events as the user is browsing the page. The `pageViewId` property should be kept the same for all these events so that they can be grouped together properly. When using the client side event reporting with JavaScript pixel and Google Tag Manager, this value is filled in automatically. |
| "productDetails": [ # The main product details related to the event. This field is required for the following event types: * `add-to-cart` * `detail-page-view` * `purchase-complete` In a `search` event, this field represents the products returned to the end user on the current page (the end user may have not finished broswing the whole page yet). When a new page is returned to the end user, after pagination/filtering/ordering even for the same query, a new `search` event with different product_details is desired. The end user may have not finished broswing the whole page yet. |
| { # Detailed product information associated with a user event. |
| "product": { # Product captures all metadata information of items to be recommended or searched. # Required. Product information. Only Product.id field is used when ingesting an event, all other product fields are ignored as we will look them up from the catalog. |
| "attributes": { # 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]} }`.
