This tutorial series aims to help developers get started with using Vonage's SMS API in conjunction with Node-RED, a popular low-code development platform. The Vonage SMS API allows users to send and receive SMS messages worldwide through a simple HTTP-based API. With the addition of Nexmo nodes to the Node-RED palette, interacting with this API has become easier. To start, developers need a Vonage API account, a virtual phone number, and install the necessary runtime and editor for Node-RED. They can then set up a flow using the Nexmo nodes to send SMS messages, including customizing parameters such as the recipient's number, message text, and timestamp. The tutorial also covers setting up a webhook endpoint to receive delivery receipts from Vonage and exposes the local server to the internet using ngrok. By following this series, developers can gain hands-on experience with sending SMS messages using Node-RED and Vonage's SMS API.
