Introduction
The Crezco Payables API is organized around REST. Our API has predictable resource-oriented URLs, accepts and returns JSON-encoded data and uses standard HTTP response codes, authentication, and verbs.
You can use the Crezco Payables API in our Sandbox environment which is separated from your Production data and does not interact with the live banking networks. The URL you call and the API key you use to authenticate the request determines whether the request is live mode or sandbox mode.
