The Zester API is organized around REST. Our API has predictable resource-oriented URLs, accepts form-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.

You can use the Zester API in test mode, which does not affect your live data or interact with other networks. 

The API key you use to authenticate the request determines whether the request is live mode (production environment) or test mode (test environment).

The Zester API differs for every account as we release new versions and tailor functionality. 

The following document is customized to your API version, with your test key and data including the following functionalities:
