You can send SMS messages using NodeJS and AWS Lambda by integrating the Twilio API with the serverless computing platform. To start, create an AWS Lambda function in the AWS Console and install the Twilio npm library to write a JavaScript code that uses the Twilio package to send SMS based on provided request parameters. The account credentials are retrieved from environment variables set up earlier. Once the function is uploaded to AWS Lambda, configure the Twilio Account by copying values such as the Account SID and Auth Token, and add them as Environment Variables within the Lambda function. Finally, test the function by sending a message with an HTTP request that includes a valid `to` number and message body. This integration leverages serverless cloud infrastructure and seamless communication capabilities to provide a reliable and efficient way to send SMS messages.
