Manage intents with the API

Intents determine which user requests are understood and what action to take. In most cases, you use the Dialogflow ES console to manage intents. In advanced scenarios, you can use the API to manage intents. This document describes how to create, list, and delete intents using the API.

Before you begin

Before you begin, complete the following steps:

Read Dialogflow basics.
Perform setup steps.

Create an agent

Go to the Dialogflow ES console.
Sign in to the console if prompted. For more information, see the Dialogflow console overview.
In the sidebar menu, expand Loading agents.
Click Create new agent.
Enter the agent name, default language, and default time zone.
Enter an existing project. To let the Dialogflow console create a project, select Create a new Google project.
Click Create.

Use IntentView to return all intent data

By default, the API returns abbreviated intent data when you create, list, or get an intent. The following samples use this default.

To retrieve all intent data, you must set the IntentView parameter to INTENT_VIEW_FULL. For more information about intent data, see the methods for the Intents type.

Create intent

The following samples show you how to create an intent. For more information about intents, see the Intents reference.

REST

To create an intent for your agent, call the create method on the intent resource.

Before using any of the request data, make the following replacements:

PROJECT_ID: your Google Cloud project ID

HTTP method and URL:

POST https://dialogflow.googleapis.com/v2/projects/PROJECT_ID/agent/intents

Request JSON body:

{
  "displayName": "ListRooms",
  "priority": 500000,
  "webhookState": "WEBHOOK_STATE_UNSPECIFIED",
  "trainingPhrases": [
    {
      "type": "EXAMPLE",
      "parts": [
        {
          "text": "What rooms are available at 10am today?"
        }
      ]
    }
  ],
  "action": "listRooms",
  "messages": [
    {
      "text": {
        "text": [
          "Here are the available rooms:"
        ]
      }
    }
  ]
}

To send your request, expand one of these options:

curl (Linux, macOS, or Cloud Shell)

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login , or by using Cloud Shell, which automatically logs you into the gcloud CLI . You can check the currently active account by running gcloud auth list.

Save the request body in a file named request.json, and execute the following command:

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "x-goog-user-project: PROJECT_ID" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://dialogflow.googleapis.com/v2/projects/PROJECT_ID/agent/intents"

PowerShell (Windows)

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login . You can check the currently active account by running gcloud auth list.

Save the request body in a file named request.json, and execute the following command:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred"; "x-goog-user-project" = "PROJECT_ID" }

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -ContentType: "application/json; charset=utf-8" `
    -InFile request.json `
    -Uri "https://dialogflow.googleapis.com/v2/projects/PROJECT_ID/agent/intents" | Select-Object -Expand Content

APIs Explorer (browser)

Copy the request body and open the method reference page. The APIs Explorer panel opens on the right side of the page. You can interact with this tool to send requests. Paste the request body in this tool, complete any other required fields, and click Execute.

You should receive a JSON response similar to the following:

Response

{
  "name": "projects/PROJECT_ID/agent/intents/5b290a94-55d6-4074-96f4-9c4c4879c2bb",
  "displayName": "ListRooms",
  "priority": 500000,
  "action": "listRooms",
  "messages": [
    {
      "text": {
        "text": [
          "Here are the available rooms:"
        ]
      }
    }
  ]
}

The path segment after intents contains your new intent ID.
