Creating Intents

Here is an example of creating an intent in a Dialogflow agent.

Set up your GCP project and authentication

Create an agent

Import the example intents and entities

Create intent

Protocol

Intents determine which user requests are understood and what action to take. In this example, we will create an intent to expand what the room reservation agent can respond to. The new intent will associate user questions about which rooms are available with the action listRooms.

  1. To create the intent, use the following curl command to access the intents endpoint. Replace project-id with your Google Cloud project ID. The command uses the gcloud command-line interface from the Google Cloud SDK to get an authorization token for the command. For instructions on setting up authorization, see Quickstart.

    curl -X POST -H "Authorization: Bearer "$(gcloud auth application-default print-access-token) -H "Content-Type: application/json; charset=utf-8" --data "{
  '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:'
          ]
        }
      }
    ],
}" "https://dialogflow.googleapis.com/v2/projects/project-id/agent/intents"

    You should see a response similar to the following:

    {
  "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:"
        ]
      }
    }
  ]
}

    If you detect intent with text of "what rooms are available at 9am?", then you should see a response similar to the following. Notice that the user intent is mapped to the listRooms action.

    {
  "responseId": "5b35eb91-084f-4072-ac08-3ed47ed6e6ae",
  "queryResult": {
    "queryText": "what rooms are available at 9am?",
    "action": "listRooms",
    "parameters": {},
    "allRequiredParamsPresent": true,
    "fulfillmentText": "Here are the available rooms:",
    "fulfillmentMessages": [
      {
        "text": {
          "text": [
            "Here are the available rooms:"
          ]
        }
      }
    ],
    "intent": {
      "name": "projects/project-id/agent/intents/5b290a94-55d6-4074-96f4-9c4c4879c2bb",
      "displayName": "ListRooms"
    },

  }
}
