Serverless JavaScript Projects 3.2: Build a Twilio and IBM Watson AWS Lambda

This video tutorial guides viewers through building a Lambda function to handle traffic from Twilio, pass it to IBM Watson, and return the response. It covers setting up a serverless application, configuring API endpoints, and handling responses in handler.js. The tutorial also includes testing the endpoint with Postman and debugging. The video concludes with finalizing the Lambda function and preparing for further enhancements.
