How to Send and Receive SMS Messages With Node.js and Azure Functions

This article explains how to use Vonage's SMS API with Azure Functions and Node.js to send and receive SMS messages. The author starts by setting up a Vonage account, installing the required libraries, and creating an Azure Function App. They then create a Webhook function that receives incoming SMS messages from Vonage and logs them to the console. To test this functionality, the author sets up a Vonage phone number, deploys the Azure Function App, and sends an SMS message using the Vonage Node.js SDK. The response is converted into emojis, demonstrating how to send a response back to the original sender.
