HTTP SMS API

We've got some basic examples in six popular languages
to help you get started using our Text Messaging APIs.

Please note: While we will continue to support our HTTP API, this is a legacy product. Active development has moved to our REST API. As such, we encourage you to use our REST API. The REST API already offers new bulk sending and message scheduling options. No new features will be added to the HTTP API.
