      • getUserPseudoId

        String getUserPseudoId()
         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.

 Do not 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 user_pseudo_id = 2 [(.google.api.field_behavior) = REQUIRED];

 can be populated from the HTTP request.

 This flag should be set only if the API request is made directly from the
 end user such as a mobile app (and not if a gateway or a server is
 processing and pushing the user events).

 This should not be set when using the JavaScript tag in
 [UserEventService.CollectUserEvent][google.cloud.discoveryengine.v1.UserEventService.CollectUserEvent].

        String getSessionId()
         A unique identifier for tracking a visitor session with a length limit of

 span.

 A general guideline to populate the session_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
 [UserEvent.user_pseudo_id][google.cloud.discoveryengine.v1.UserEvent.user_pseudo_id]
 as prefix.
        string session_id = 6;

      • getAttributionToken

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

 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

      • getAttributesCount

        int getAttributesCount()
         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.

        boolean containsAttributes​(String key)
         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.
