public class ConversationsClient implements BackgroundResource

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:

 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().

The surface of this class includes several types of Java methods for each of the API's methods:

1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
3. A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

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 ConversationsSettings to create(). For example:

To customize credentials:

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

To customize the endpoint:

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

createConversation(CreateConversationRequest request)

public final Conversation createConversation(CreateConversationRequest request)

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.

Sample code:

 try (ConversationsClient conversationsClient = ConversationsClient.create()) {
   CreateConversationRequest request =
       CreateConversationRequest.newBuilder()
           .setParent(ProjectName.of("[PROJECT]").toString())
           .setConversation(Conversation.newBuilder().build())
           .setConversationId("conversationId-1676095234")
           .build();
   Conversation response = conversationsClient.createConversation(request);
 }
 

Parameter

Name	Description
request	CreateConversationRequest The request object containing all of the parameters for the API call.

Returns
