This summary provides an overview of how to use the Twilio Java Helper Library with AWS CDK to deploy an AWS Lambda function that sends SMS messages using Twilio's Programmable SMS API. The deployment process involves setting up a Java development environment, creating a new CDK project, defining the Lambda function and its handler, packaging the code for deployment, defining the API Gateway HTTP API, and deploying the application to an AWS account. The application can be tested by sending a POST JSON request to the deployed API endpoint with a receiver phone number and message.
