Class ConversationsClient (4.54.0)

GitHub RepositoryProduct Reference

Service Description: Service for managing Conversations.

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 (ConversationsClient conversationsClient = ConversationsClient.create()) {
   LocationName parent = LocationName.of("[PROJECT]", "[LOCATION]");
   Conversation conversation = Conversation.newBuilder().build();
   Conversation response = conversationsClient.createConversation(parent, conversation);
 }

Note: close() needs to be called on the ConversationsClient 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

CreateConversation

Creates a new conversation. Conversations are auto-completed after 24 hours.

Conversation Lifecycle: There are two stages during a conversation: Automated Agent Stage and Assist Stage.

For Automated Agent Stage, there will be a dialogflow agent responding to user queries.

For Assist Stage, there's no dialogflow agent responding to user queries. But we will provide suggestions which are generated from conversation.

If Conversation.conversation_profile is configured for a dialogflow agent, conversation will start from Automated Agent Stage, otherwise, it will start from Assist Stage. And during Automated Agent Stage, once an Intent with Intent.live_agent_handoff is triggered, conversation will transfer to Assist Stage.

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

  • createConversation(CreateConversationRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • createConversation(LocationName parent, Conversation conversation)

  • createConversation(ProjectName parent, Conversation conversation)

  • createConversation(String parent, Conversation conversation)

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

  • createConversationCallable()

ListConversations

Returns the list of all conversations in the specified project.

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 ConversationsSettings 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
 ConversationsSettings conversationsSettings =
     ConversationsSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 ConversationsClient conversationsClient = ConversationsClient.create(conversationsSettings);

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
 ConversationsSettings conversationsSettings =
     ConversationsSettings.newBuilder().setEndpoint(myEndpoint).build();
 ConversationsClient conversationsClient = ConversationsClient.create(conversationsSettings);

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
 ConversationsSettings conversationsSettings =
     ConversationsSettings.newHttpJsonBuilder().build();
 ConversationsClient conversationsClient = ConversationsClient.create(conversationsSettings);
