# Discovery Engine API . projects . locations . dataStores . userEvents

## Instance Methods

Close httplib2 connections.

Writes a single user event from the browser. This uses a GET request to due to browser restriction of POST-ing to a third-party domain. This method is used only by the Discovery Engine API JavaScript pixel and Google Tag Manager. Users should not call this method directly.

Bulk import of user events. Request processing might be synchronous. Events that already exist are skipped. Use this method for backfilling historical user events. Operation.response is of type ImportResponse. Note that it is possible for a subset of the items to be successfully inserted. Operation.metadata is of type ImportMetadata.

Deletes permanently all user events specified by the filter provided. Depending on the number of events specified by the filter, this operation could take hours or days to complete. To test a filter, use the list command first.

Writes a single user event.

### Method Details

`close()`

    Close httplib2 connections.

`collect(parent, ets=None, uri=None, userEvent=None, x__xgafv=None)`

    Writes a single user event from the browser. This uses a GET request to due to browser restriction of POST-ing to a third-party domain. This method is used only by the Discovery Engine API JavaScript pixel and Google Tag Manager. Users should not call this method directly.

    Args:
      parent: string, Required. The parent resource name. If the collect user event action is applied in DataStore level, the format is: `projects/{project}/locations/{location}/collections/{collection}/dataStores/{data_store}`. If the collect user event action is applied in Location level, for example, the event with Document across multiple DataStore, the format is: `projects/{project}/locations/{location}`. (required)
      ets: string, The event timestamp in milliseconds. This prevents browser caching of otherwise identical get requests. The name is abbreviated to reduce the payload bytes.
      uri: string, The URL including cgi-parameters but excluding the hash fragment with a length limit of 5,000 characters. This is often more useful than the referer URL, because many browsers only send the domain for third-party requests.
      userEvent: string, Required. URL encoded UserEvent proto with a length limit of 2,000,000 characters.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

        { # Message that represents an arbitrary HTTP body. It should only be used for payload formats that can't be represented as JSON, such as raw binary or an HTML page. This message can be used both in streaming and non-streaming API methods in the request as well as the response. It can be used as a top-level request field, which is convenient if one wants to extract parameters from either the URL or HTTP template into the request fields and also want access to the raw HTTP body. Example: message GetResourceRequest { // A unique request id. string request_id = 1; // The raw HTTP body is bound to this field. google.api.HttpBody http_body = 2; } service ResourceService { rpc GetResource(GetResourceRequest) returns (google.api.HttpBody); rpc UpdateResource(google.api.HttpBody) returns (google.protobuf.Empty); } Example with streaming methods: service CaldavService { rpc GetCalendar(stream google.api.HttpBody) returns (stream google.api.HttpBody); rpc UpdateCalendar(stream google.api.HttpBody) returns (stream google.api.HttpBody); } Use of this type only changes how the request and response bodies are handled, all other features will continue to work unchanged.
      "contentType": "A String", # The HTTP Content-Type header value specifying the content type of the body.
      "data": "A String", # The HTTP request/response body as raw binary.
      "extensions": [ # Application specific response metadata. Must be set in the first response for streaming APIs.
        {
          "a_key": "", # Properties of the object. Contains field @type with type URL.
        },
      ],
    }

`import_(parent, body=None, x__xgafv=None)`

    Bulk import of user events. Request processing might be synchronous. Events that already exist are skipped. Use this method for backfilling historical user events.

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.

`purge(parent, body=None, x__xgafv=None)`

    Deletes permanently all user events specified by the filter provided. Depending on the number of events specified by the filter, this operation could take hours or days to complete. To test a filter, use the list command first.

    Args:
      parent: string, Required. The resource name of the catalog under which the events are created. The format is `projects/{project}/locations/global/collections/{collection}/dataStores/{dataStore}`. (required)
      body: object, The request body.

      "filter": "A String", # Required. The filter string to specify the events to be deleted with a length limit of 5,000 characters. The eligible fields for filtering are: * `eventType`: Double quoted UserEvent.event_type string. * `eventTime`: in ISO 8601 "zulu" format. * `userPseudoId`: Double quoted string. Specifying this will delete all events associated with a visitor. * `userId`: Double quoted string. Specifying this will delete all events associated with a user. Note: This API only supports purging a max range of 30 days. Examples: * Deleting all events in a time range: `eventTime > "2012-04-23T18:25:43.511Z" eventTime < "2012-04-23T18:30:43.511Z"` * Deleting specific eventType in a time range: `eventTime > "2012-04-23T18:25:43.511Z" eventTime < "2012-04-23T18:30:43.511Z" eventType = "search"` * Deleting all events for a specific visitor in a time range: `eventTime > "2012-04-23T18:25:43.511Z" eventTime < "2012-04-23T18:30:43.511Z" userPseudoId = "visitor1024"` * Deleting the past 30 days of events inside a DataStore: `*` The filtering fields are assumed to have an implicit AND.
      "force": True or False, # The `force` field is currently not supported. Purge user event requests will permanently delete all purgeable events.

    Writes a single user event.

    Args:
      parent: string, Required. The parent resource name. If the write user event action is applied in DataStore level, the format is: `projects/{project}/locations/{location}/collections/{collection}/dataStores/{data_store}`.

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.

The value must be one of: * RecommendResponse.attribution_token for events that are the result of RecommendationService.Recommend. * 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.

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.
      "documents": [ # List of Documents associated with this user event.

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 UserEvent.documents is desired.
        { # Detailed document information associated with a user event.
          "conversionValue": 3.14, # Optional. The conversion value associated with this Document. Must be set if UserEvent.event_type is "conversion". For example, a value of 1000 signifies that 1000 seconds were spent viewing a Document for the `watch` conversion type.

One example is for `search` events, the associated SearchRequest may contain a filter expression in SearchRequest.filter conforming to https://google.aip.dev/160#filtering. Similarly, for `view-item-list` events that are generated from a RecommendRequest, this field may be populated directly from RecommendRequest.filter conforming to https://google.aip.dev/160#filtering. The value must be a UTF-8 encoded string with a length limit of 1,000 characters. Otherwise, an `INVALID_ARGUMENT` error is returned.
      "mediaInfo": { # Media-specific user event information. # Media-specific info.
        "mediaProgressDuration": "A String", # The media progress time in seconds, if applicable. For example, if the end user has finished 90 seconds of a playback video, then MediaInfo.media_progress_duration.seconds should be set to 90.

Other event types should not set this field. Otherwise, an `INVALID_ARGUMENT` error is returned.
        "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.

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.

The value must be one of: * RecommendResponse.attribution_token for events that are the result of RecommendationService.Recommend. * 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.

One example is for `search` events, the associated SearchRequest may contain a filter expression in SearchRequest.filter conforming to https://google.aip.dev/160#filtering. Similarly, for `view-item-list` events that are generated from a RecommendRequest, this field may be populated directly from RecommendRequest.filter conforming to https://google.aip.dev/160#filtering. The value must be a UTF-8 encoded string with a length limit of 1,000 characters. Otherwise, an `INVALID_ARGUMENT` error is returned.

Other event types should not set this field. Otherwise, an `INVALID_ARGUMENT` error is returned.
        "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.
