Our new serverless REST API makes it easy to deploy code to Twilio Functions, our serverless code execution environment, and Twilio Assets, our static file hosting service. This new API allows code written in NodeJS and static asset files to be created locally and deployed to the Twilio Serverless environment. The REST API can be used directly with the Twilio helper libraries, or via the Twilio CLI and the Twilio Serverless Toolkit.
Existing Functions and Assets are incompatible with the new API, but they will remain accessible via the web Console as they are today.
