# API Reference

## Introduction

The Gluwa API follows [REST](http://en.wikipedia.org/wiki/Representational_State_Transfer) design guideline. The API has predictable resource-oriented URL's and returns [JSON-encoded](http://www.json.org/) responses, and uses standard HTTP response codes, authentication, and verbs.

Please note that the sandbox environment is deprecated and will be replaced with an alternative solution in the future.

### Base URL

### HTTPS Over HTTP

All API requests must be made over [HTTPS](http://en.wikipedia.org/wiki/HTTP_Secure). Calls made over plain HTTP will fail. 

### Client SDK's

By default, the Gluwa API Docs demonstrate using curl to interact with the API over HTTP. You could also use one of our official Software Development Kits (SDK) to see interact with our API.
