Build an SMS Web Service With Java

The Vonage SMS API service allows developers to send and receive SMS messages globally, with a Java SDK providing an easier-to-use alternative to REST APIs. The tutorial builds on existing knowledge of sending SMS messages with Java, creating a web service around it using Gradle, Gretty, and the Vonage Java SDK. The process involves setting up a Gradle project, downloading the Vonage Java SDK, building a web service, and configuring the servlet in the servlet container. The resulting web service can be tested using Postman, allowing developers to send SMS messages with their chosen virtual phone number and API credentials.
