API Reference

The Rayo API is based on REST. It has easy to understand URLs, accepts JSON request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.

You can use the Rayo API in QA for Sandbox testing purposes , which doesn't affect your live data or interact with the fulfillment networks. The host and API key you use to authenticate the request determines whether the request is production mode or QA mode.

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

Authentication

The Rayo API uses API keys to generate JWT to authenticate requests. You can view and manage your API keys in Rayo AVA account.

Your API keys have your role and permissions set up to the account level you are subscribed to. Do not share your secret API keys in publicly accessible areas such as GitHub, client-side code, and so on.

All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail.
