At APIDays in Sydney, we announced the preview of Telstra’s new 127.0.0.1 (home) for APIs, which currently consists of a public SMS API. The preview is open to all developers, and those who are interested in participating can register at http://dev.telstra.com

Check out the SMS API Quickstart Guide for an overview

As this is a Preview, we would love you to help us out with feedback, so please let us know through the forums (https://dev.telstra.com/forum) or send us an email to t.dev@team.telstra.com
