Methods

#attributes

def attributes() -> ::Google::Protobuf::Map{::String => ::Google::Cloud::DiscoveryEngine::V1::CustomAttribute}

Returns

(::Google::Protobuf::Map{::String => ::Google::Cloud::DiscoveryEngine::V1::CustomAttribute}) — Extra user event features to include in the recommendation model. These attributes must NOT contain data that needs to be parsed or processed further, e.g. JSON or other encodings.

If you provide custom attributes for ingested user events, also include them in the user events that you associate with prediction requests. Custom attribute formatting must be consistent between imported events and events provided with prediction requests. This lets the Discovery Engine API use those custom attributes when training models and serving predictions, which helps improve recommendation quality.

This field needs to pass all below criteria, otherwise an INVALID_ARGUMENT error is returned:
- The key must be a UTF-8 encoded string with a length limit of 5,000 characters.
- For text attributes, at most 400 values are allowed. Empty values are not allowed. Each value must be a UTF-8 encoded string with a length limit of 256 characters.
- For number attributes, at most 400 values are allowed.
For product recommendations, an example of extra user information is traffic_channel, which is how a user arrives at the site. Users can arrive at the site by coming to the site directly, coming through Google search, or in other ways.

#attribution_token

def attribution_token() -> ::String

Returns

(::String) — Token to attribute an API response to user action(s) to trigger the event.

Highly recommended for user events that are the result of RecommendationService.Recommend. This field enables accurate attribution of recommendation model performance.

The value must be one of:

- SearchResponse.attribution_token for events that are the result of SearchService.Search.
This token enables us to accurately attribute page view or conversion completion 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 RecommendResponse.attribution_token as a URL parameter to product K's page. When recording events on product K's page, log the RecommendResponse.attribution_token to this field.
