Google Cloud Dialogflow ES

The Google Cloud Dialogflow modules enable you to monitor and respond to fulfillments, or create, update, retrieve, and delete agents, contexts, entities, and intents in your Google Cloud Dialogflow.

Getting Started with Google Cloud Dialogflow

Prerequisites

In order to use Google Cloud Dialogflow with Integromat, it is necessary to have a Google account. If you do not have one, you can create a Google account at dialogflow.cloud.google.com.

The module dialog fields that are displayed in bold (in the Integromat scenario, not in this documentation article) are mandatory!

Connecting Google Cloud Dialogflow to Integromat

To connect your Google Cloud Dialogflow account to Integromat you need to obtain the project's Client ID and Client Secret in the Google API Console.

1. Sign in to the Google API console using your Google credentials.

2. Click CREATE PROJECT.

Fulfillment

Watch for Fulfillments

Triggers when an intent action is performed.

The webhook URL needs to be generated in Integromat and then added to Google Cloud Dialogflow ES's Fulfillment settings.

1. Add the Watch for Fulfillment module to your Integromat scenario.

2. Generate and copy the webhook URL.

PSBTw5sapq.gif

3. Log in to your Google Cloud Dialogflow ES account.

4. Go to Fulfillment and enable webhooks.

BWQEcEJT9O.gif

5. Enter the webhook URL you have copied in step two to the URL field, and click Save.

xSDBEaIHPt.gif

6. Enable webhooks for the desired intent.

iIG5hACp6V.gif

Now, every time an intent with fulfillment enabled is matched, the Watch for Fulfillment module in your Integromat scenario is triggered.

Response to Fulfillment

When the Watch for Fulfillment module is triggered, the Response to Fulfillment module responds to Dialogflow with information on how to proceed.

The Watch for Fulfillment module must be added to the scenario before the Response to Fulfillment module.

Connection Establish a connection to your Google Cloud Dialogflow ES.
Fulfillment Messages

Add response messages. Select the messages to be presented to the user.

Text Specify the text response message.
Image Specify the image response message.

Card Specify the card response message.
Payload Specify a custom platform-specific response.
Simple Responses Specify the voice and text-only responses for Actions on Google.
Basic Card Specify the basic card response for Actions on Google.
Suggestions Specify the suggestion chips for Actions on Google.
Link Out Suggestion Specify the link out suggestion chip for Actions on Google.
List Select Specify the list card response for Actions on Google.
Carousel Select Specify the carousel card response for Actions on Google.
Browse Carousel Card  Specify the browse carousel card for Actions on Google.
Table Card Specify the table card for Actions on Google.
Media Content  Specify the media content card for Actions on Google.
Source Enter a custom field used to identify the webhook source.
Payload Enter the custom payload data as key-value pairs.
Output Contexts

When an intent is matched, any configured output contexts for that intent become active. Multiple output contexts can be applied to an intent.

Name

Enter the path to the context.

Example projects/zinc-involution-290910/agent/sessions/4380a89f-6461-ad33-7f89-652af5233856/contexts/test_context

Lifespan Count Defines the number of conversational turns for which the context remains active. The default lifespan is five conversational turns for normal intents and two conversational turns for follow-up intents. You can override the default lifespan for any contexts. In addition, all contexts expire after 20 minutes of becoming active. When an intent is matched with an output context that is already active, the lifespan and expiration timer are reset.
 Parameters Define parameters. For more details, please refer to the Dialogflow Documentation.

 

Followup Event Input When the Followup Event Input is set, Dialogflow ignores the Fulfillment Text, Fulfillment Messages, and Payload fields. When Dialogflow receives a webhook response that includes an event, it immediately triggers the corresponding intent in which it was defined.

Classification Threshold To set the score value to filter out false positive results and still get variety in matched natural language inputs for your agent, you can tune the machine learning classification threshold. If the returned score value is less than the threshold value, then a fallback intent will be triggered, or, if there are no fallback intents defined, no intent will be triggered. The score values range from 0.0 (completely uncertain) to 1.0 (completely certain). If set to 0.0, the default of 0.3 is used.

  • Text
    A conversational query in the form of text.
  • Event
    An event that specifies which intent to trigger.
Query Input - Audio Configuration

Set the query to instruct the speech recognizer how to process the audio content. For a description of the fields, please refer to the Dialogflow documentation.

Query Input - Text

Specify the text to represent the natural language text to be processed. For a description of the fields, please refer to the Dialogflow documentation.

Query Input - Event

Specify the event to match intents by event name instead of the natural language input. For a description of the fields, please refer to the Dialogflow documentation.

Is Fallback Select the Yes option to set this intent as a fallback intent.
ML Disabled

Select the Yes option to disable Machine Learning for the intent.
