Documentation

Overview

Package dialogflow provides access to the Dialogflow API.

This package is DEPRECATED. Use package cloud.google.com/go/dialogflow/apiv2 instead.

For product documentation, see: https://cloud.google.com/dialogflow/

Creating a client

Usage example: 

import "google.golang.org/api/dialogflow/v2"
...
ctx := context.Background()
dialogflowService, err := dialogflow.NewService(ctx)

In this example, Google Application Default Credentials are used for authentication.

For information on how to create and obtain Application Default Credentials, see https://developers.google.com/identity/protocols/application-default-credentials.

Other authentication options

By default, all available scopes (see "Constants") are used to authenticate. To restrict scopes, use option.WithScopes: 

dialogflowService, err := dialogflow.NewService(ctx, option.WithScopes(dialogflow.DialogflowScope))

To use an API key for authentication (note: some APIs do not support API keys), use option.WithAPIKey: 

dialogflowService, err := dialogflow.NewService(ctx, option.WithAPIKey("AIza..."))

To use an OAuth token (e.g., a user token obtained via a three-legged OAuth flow), use option.WithTokenSource: 

config := &oauth2.Config{...}
// ...
token, err := config.Exchange(ctx, ...)
dialogflowService, err := dialogflow.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))

See https://godoc.org/google.golang.org/api/option/ for details on options.

The states of a CX session are represented by pages. For each flow, you define many pages, where your combined pages can handle a complete conversation on the topics the flow is designed for. At any given moment, exactly one page is the current page, the current page is considered active, and the flow associated with that page is considered active. Every flow has a special start page. When a flow initially becomes active, the start page page becomes the current page. For each conversational turn, the current page will either stay the same or transition to another page. You configure each page to collect information from the end-user that is relevant for the conversational state represented by the page. For more information, see the Page guide (https://cloud.google.com/dialogflow/cx/docs/concept/page).

Response messages are also used for output audio synthesis. The approach is as follows: * If at least one OutputAudioText response is present, then all OutputAudioText responses are linearly concatenated, and the result is used for output audio synthesis. * If the OutputAudioText responses are a mixture of text and SSML, then the concatenated result is treated as SSML; otherwise, the result is treated as either text or SSML as appropriate. The agent designer should ideally use either text or SSML consistently throughout the bot design. * Otherwise, all Text responses are linearly concatenated, and the result is used for output audio synthesis. This approach allows for more sophisticated user experience scenarios, where the text displayed to the user may differ from what is heard.
