   viewed.
 * `detail-page-view`: Products detail page viewed.
 * `home-page-view`: Homepage viewed.

 * `promotion-not-offered`: Promotion is not offered to a user.
 * `purchase-complete`: User finishing a purchase.
 * `search`: Product search.
 * `shopping-cart-page-view`: User viewing a shopping cart.
        string event_type = 1 [(.google.api.field_behavior) = REQUIRED];

      • getVisitorId

        String getVisitorId()
         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.

 The field must be a UTF-8 encoded string with a length limit of 128
 characters. Otherwise, an INVALID_ARGUMENT error is returned.

 The field should not contain PII or user-data. We recommend to use Google
 Analytics [Client
 ID](https://developers.google.com/analytics/devguides/collection/analyticsjs/field-reference#clientId)
 for this field.
        string visitor_id = 2 [(.google.api.field_behavior) = REQUIRED];
        Returns:
        The visitorId.

      • getVisitorIdBytes

      • getSessionId

        String getSessionId()
         A unique identifier for tracking a visitor session with a length limit of
 128 bytes. A session is an aggregation of an end user behavior in a time
 span.

 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.
        string session_id = 21;
        Returns:
        The sessionId.

      • getSessionIdBytes

        int getAttributesCount()
         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.

 error is returned:

   allowed. Each value must be a UTF-8 encoded string with a length limit of
   256 characters.
