How to Connect SAP Leonardo to Google Dialogflow: a Simple Guide

 

Overview of SAP Leonardo and Google Dialogflow

 

  • SAP Leonardo is a comprehensive digital innovation system that integrates technologies like IoT, machine learning, and blockchain.
  •  

  • Google Dialogflow is a natural language understanding platform used to design and integrate a conversational user interface into mobile apps, web applications, devices, etc.

 

Pre-Requisites

 

  • An SAP Cloud Platform account with the necessary credentials and permissions.
  •  

  • Access to the SAP Leonardo Machine Learning Foundation services.
  •  

  • A Google Cloud Platform account with Dialogflow API enabled.
  •  

  • Basic understanding of RESTful APIs.

 

Set Up SAP Leonardo Credentials

 

  • Log into your SAP Cloud Platform Console.
  •  

  • Navigate to the “SAP Leonardo Machine Learning” section.
  •  

  • Under "Services," find and select the required service (e.g., Text Classification), then click on "Go to Service" for configuration options.
  •  

  • Retrieve API keys or OAuth tokens for the service that you plan to integrate with Dialogflow.

 

Configure Google Dialogflow

 

  • Access the Dialogflow Console from the Google Cloud Platform by navigating to the 'APIs & Services' section.

  • Input the webhook URL, which you will set up to handle requests, into this section. This URL will need to manage calls to SAP Leonardo’s APIs.

 

Develop the Integration Webhook

 

  • Set up a server environment (Node.js, Python, etc.) to create a webhook that will connect SAP Leonardo and Dialogflow.
  •  

  • Write a function to process the JSON payload from Dialogflow and extract the necessary intent information.
  •  

  • Embed the SAP Leonardo API request within this function. Below is a sample in Node.js:

 


const express = require('express');
const bodyParser = require('body-parser');
const request = require('request');
const app = express();

app.use(bodyParser.json());
app.post('/webhook', (req, res) => {
  const intent = req.body.queryResult.intent.displayName;
  
  if(intent === 'Your Intent Name'){
    // Example SAP Leonardo API call
    const url = 'https://api.sap.com/textClassification/';
    const options = {
      url: url,
      headers: {
        'Authorization': 'Bearer YOUR_OAUTH_TOKEN',
        'Content-Type': 'application/json'
      },
      body: JSON.stringify(req.body)
    };
    
    request.post(options, (error, response, body) => {
      if (!error && response.statusCode == 200) {
        const data = JSON.parse(body);
        // Process and send response back to Dialogflow
        res.json({ "fulfillmentText": "Response from SAP Leonardo" });
      }
    });
  }
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

 

Test the Integration

 

  • Deploy your server and webhook to a service like Heroku, AWS, or Google Cloud Functions.
  •  

  • Use Dialogflow’s 'Integrations' tab to test the agent in action.
  •  

  • Check logs and responses from both SAP Leonardo and Dialogflow to ensure the correct interaction and data flow.

 

Monitor and Maintain the Integration

 

  • Regularly monitor your application logs to identify integration issues quickly.
  •  

  • Implement error-handling mechanisms within your webhook to manage unexpected behaviors or API errors.
  •  

  • Stay updated with any changes to API endpoints or authentication methods on both SAP Leonardo and Google Dialogflow platforms.
