Methods

Create()

public static SessionsClient Create()

Synchronously creates a SessionsClient using the default credentials, endpoint and settings. To specify custom credentials or other settings, use SessionsClientBuilder.

Returns
Type	Description
SessionsClient	The created SessionsClient.

CreateAsync(CancellationToken)

public static Task<SessionsClient> CreateAsync(CancellationToken cancellationToken = default)

Asynchronously creates a SessionsClient using the default credentials, endpoint and settings. To specify custom credentials or other settings, use SessionsClientBuilder.

Parameter
Name	Description
cancellationToken	CancellationToken The CancellationToken to use while creating the client.

Returns
Type	Description
TaskSessionsClient	The task representing the created SessionsClient.

DetectIntent(DetectIntentRequest, CallSettings)

public virtual DetectIntentResponse DetectIntent(DetectIntentRequest request, CallSettings callSettings = null)

Processes a natural language query and returns structured, actionable data as a result. This method is not idempotent, because it may cause contexts and session entity types to be updated, which in turn might affect results of future queries.

If you might use Agent Assist or other CCAI products now or in the future, consider using [AnalyzeContent][google.cloud.dialogflow.v2beta1.Participants.AnalyzeContent] instead of DetectIntent. AnalyzeContent has additional functionality for Agent Assist and other CCAI products.

Note: Always use agent versions for production traffic. See Versions and environments.

Parameters
Name	Description
request	DetectIntentRequest The request object containing all of the parameters for the API call.
callSettings	CallSettings If not null, applies overrides to this RPC call.

Returns
Type	Description
DetectIntentResponse	The RPC response.

Example

// Create client
SessionsClient sessionsClient = SessionsClient.Create();
// Initialize request argument(s)
DetectIntentRequest request = new DetectIntentRequest
{
    SessionAsSessionName = SessionName.FromProjectSession("[PROJECT]", "[SESSION]"),
    QueryParams = new QueryParameters(),
    QueryInput = new QueryInput(),
    OutputAudioConfig = new OutputAudioConfig(),
    InputAudio = ByteString.Empty,
    OutputAudioConfigMask = new FieldMask(),
};
// Make the request
DetectIntentResponse response = sessionsClient.DetectIntent(request);

DetectIntent(SessionName, QueryInput, CallSettings)

public virtual DetectIntentResponse DetectIntent(SessionName session, QueryInput queryInput, CallSettings callSettings = null)

Processes a natural language query and returns structured, actionable data as a result. This method is not idempotent, because it may cause contexts and session entity types to be updated, which in turn might affect results of future queries.

If you might use Agent Assist or other CCAI products now or in the future, consider using [AnalyzeContent][google.cloud.dialogflow.v2beta1.Participants.AnalyzeContent] instead of DetectIntent. AnalyzeContent has additional functionality for Agent Assist and other CCAI products.

Note: Always use agent versions for production traffic. See Versions and environments.

Parameters
Name	Description
session	SessionName Required. The name of the session this query is sent to. Supported formats: `projects/<Project ID>/agent/sessions/<Session ID>, projects/<Project ID>/locations/<Location ID>/agent/sessions/<Session ID>, projects/<Project ID>/agent/environments/<Environment ID>/users/<User ID>/sessions/<Session ID>, projects/<Project ID>/locations/<Location ID>/agent/environments/<Environment ID>/users/<User ID>/sessions/<Session ID>, If Location ID is not specified we assume default 'us' location. If Environment ID is not specified, we assume default 'draft' environment (Environment ID might be referred to as environment name at some places). If User ID is not specified, we are using "-". It's up to the API caller to choose an appropriate Session ID and User Id. They can be a random number or some type of user and session identifiers (preferably hashed). The length of the Session ID and User ID must not exceed 36 characters. For more information, see the API interactions guide. Note: Always use agent versions for production traffic. See Versions and environments.
