# Úvod

hiMail API (version 1.0) is organized around [REST](http://en.wikipedia.org/wiki/Representational_State_Transfer). Our API has predictable resource-oriented URLs, accepts [form-encoded](https://en.wikipedia.org/wiki/POST_\(HTTP\)#Use_for_submitting_web_forms) request bodies, returns [JSON-encoded](http://www.json.org/) responses, and uses standard HTTP response codes, authentication, and verbs.

The hiMail API may differ as we release new versions over time. Log in to your dashboard of hiMail to see the particular version, API base URI and authentication key.
