The Whiplash API.

Using the Whiplash API you can create an application to do any task you would normally do on WhiplashMerch.com. For example, you could use the API to get a list of all orders that have been shipped recently, change order addresses before they've gone out, create new orders and more.

The Whiplash API is implemented as JSON or XML over HTTP using all four verbs (GET/POST/PUT/DELETE). Each resource, like Order, Item, etc., has its own endpoints.

Authentication

An authentification token is required for all API requests. It should be included in an X-API-KEY header.

Your API key is available on your preferences page.

Versioning

The current version of the Whiplash API is 1. You may optionally specify which API version you'd like in an X-API-VERSION header (if, for instance, you wanted to continue to use an older API version when a new one is released). The default API version will always be the most recent, though users would typically be notified with a new API version release. Newly added features or endpoints to any given API version will be backward compatible.
