How to Integrate Google Dialogflow with HubSpot

Set Up Google Dialogflow

• Visit the [Dialogflow Console](https://dialogflow.cloud.google.com/) and log in with your Google Account.
• Create a new project if you don't already have one. This will be your Dialogflow agent.
• Navigate to the agent settings and gather the project ID and the service account details for your setup.
• Ensure "API Enablement" for the Dialogflow API on your project in the Google Cloud Console.

Create a Service Account in Dialogflow

• Access the Google Cloud Console and navigate to the "IAM & Admin" section. Select "Service Accounts."
• Create a new service account. You'll need to grant this account the "Dialogflow API Client" role and any other roles your integration might require.
• Generate a new JSON key for your service account. Download and store this JSON file securely, as it contains the credentials needed to access Dialogflow programmatically.

Prepare HubSpot for Integration

• Log into your HubSpot account and navigate to "Settings" > "Integrations" > "API Key" to create or retrieve your HubSpot API key.
• Set up a mechanism in HubSpot to handle incoming requests. This could be a workflow, webhook, or custom code depending on your needs.

Set Up Your Environment for Coding

• Ensure that your development environment has access to the necessary SDKs and libraries. For JavaScript environments, the Node.js Dialogflow client library is essential.
• Install the Dialogflow client library:

npm install dialogflow

Process User Input in Dialogflow

• Create Intents in Dialogflow to handle user input. Define the training phrases, responses, and any required parameters.
• Utilize Dialogflow's Fulfillment to call webhooks as necessary. This allows data to be sent and received from HubSpot as needed.

Integrate Google Dialogflow with HubSpot

• Write code to handle communication between Dialogflow and HubSpot. This may involve using the HubSpot API to retrieve or send data depending on your bot’s needs.

const dialogflow = require('@google-cloud/dialogflow');
const sessionClient = new dialogflow.SessionsClient({ keyFilename: 'path/to/your/service-account-file.json' });

async function detectIntent(projectId, sessionId, query, languageCode) {
  const sessionPath = sessionClient.projectAgentSessionPath(projectId, sessionId);

  const request = {
    session: sessionPath,
    queryInput: {
      text: {
        text: query,
        languageCode: languageCode,
      },
    },
  };

  const responses = await sessionClient.detectIntent(request);
  return responses[0];
}

Connect Dialogflow Webhooks to HubSpot

• Create a Dialogflow Fulfillment Webhook URL that points to a service capable of processing Dialogflow requests and sending queries or data to HubSpot.
• Parse Dialogflow webhook request JSON to extract information and process it accordingly.
• Associate the webhook with HubSpot data actions like creating contacts or updating tickets using HubSpot API, making RESTful API calls as necessary.

Test Your Integration

• Interact with your bot in Dialogflow's test console or through an integrated channel (like a website) to verify the dialog flow and HubSpot integration.
• Check HubSpot to see the results of any actions your bot takes, ensuring the integration works as intended.
