Class UserEventServiceClient (2.55.0)

GitHub RepositoryProduct Reference

Service Description: Service for ingesting end user actions on the customer website.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (UserEventServiceClient userEventServiceClient = UserEventServiceClient.create()) {
   WriteUserEventRequest request =
       WriteUserEventRequest.newBuilder()
           .setParent("parent-995424086")
           .setUserEvent(UserEvent.newBuilder().build())
           .setWriteAsync(true)
           .build();
   UserEvent response = userEventServiceClient.writeUserEvent(request);
 }
 

Note: close() needs to be called on the UserEventServiceClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods
Method Description Method Variants

WriteUserEvent

Writes a single user event.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • writeUserEvent(WriteUserEventRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • writeUserEventCallable()

CollectUserEvent

Writes a single user event from the browser. This uses a GET request to due to browser restriction of POST-ing to a 3rd party domain.

This method is used only by the Retail API JavaScript pixel and Google Tag Manager. Users should not call this method directly.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • collectUserEvent(CollectUserEventRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • collectUserEventCallable()

PurgeUserEvents

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.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • purgeUserEventsAsync(PurgeUserEventsRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • purgeUserEventsOperationCallable()

  • purgeUserEventsCallable()

ImportUserEvents

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.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • importUserEventsAsync(ImportUserEventsRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • importUserEventsOperationCallable()

  • importUserEventsCallable()

RejoinUserEvents

Starts a user-event rejoin operation with latest product catalog. Events are not annotated with detailed product information for products that are missing from the catalog when the user event is ingested. These events are stored as unjoined events with limited usage on training and serving. You can use this method to start a join operation on specified events with the latest version of product catalog. You can also use this method to correct events joined with the wrong product catalog. A rejoin operation can take hours or days to complete.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • rejoinUserEventsAsync(RejoinUserEventsRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • rejoinUserEventsOperationCallable()

  • rejoinUserEventsCallable()

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of UserEventServiceSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 UserEventServiceSettings userEventServiceSettings =
     UserEventServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 UserEventServiceClient userEventServiceClient =
     UserEventServiceClient.create(userEventServiceSettings);
 

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 UserEventServiceSettings userEventServiceSettings =
     UserEventServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 UserEventServiceClient userEventServiceClient =
     UserEventServiceClient.create(userEventServiceSettings);
 

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 UserEventServiceSettings userEventServiceSettings =
     UserEventServiceSettings.newHttpJsonBuilder().build();
 UserEventServiceClient userEventServiceClient =
     UserEventServiceClient.create(userEventServiceSettings);
