Interface UserEventOrBuilder (2.55.0)

Extra user event features to include in the recommendation model.

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 Retail 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.

map<string, .google.cloud.retail.v2.CustomAttribute> attributes = 7;

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. The value must be a valid SearchResponse.attribution_token for user events that are the result of SearchService.Search.

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.

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.

A general guideline to populate the sesion_id:

1. If user has no activity for 30 min, a new session_id should be assigned.
2. The session_id should be unique across users, suggest use uuid or add visitor_id as prefix.

Required. A unique identifier for tracking visitors.

For example, this could be implemented with an HTTP cookie, which should be able to uniquely identify a visitor on a single device. This unique identifier should not change if the visitor log in/out of the website.

Don't set the field to the same fixed ID for different users. This mixes the event history of those users together, which results in degraded model quality.
