Tweeting via SMS using Bandwidth’s V2 Messaging API, NodeJS, the Twitter API, and secure callbacks

The text discusses how to integrate Bandwidth's APIs, specifically the Messaging V2 API, with other tools and APIs. It provides an example of combining Bandwidth's Messaging V2 API with Twitter's API to enable users to tweet using only SMS. The guide assumes that the reader already has a configured account with Bandwidth for V2 messaging. The basic structure of this project involves setting up a POST route on a server that receives callbacks from Bandwidth when an SMS message comes in, and then forwarding the data to Twitter to create a tweet. The guide also covers secure callbacks using Basic Auth credentials.
