The Whiplash API

Using the Whiplash API you can create an application to do any task you would normally do on
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 most common type of integration is notifying Whiplash of an order that needs to ship. In that scenario, there are four basic steps to cover:

  1. Authenticate your connection
  2. Create an Item, which represents a product in a specific size, style, and color
  3. Create an Order, which contains the address and shipping method
  4. Create an OrderItem, which references both the Order and the Item, telling Whiplash what product to ship.

Note that your implentation of each of these steps should check for the existence of the Whiplash object prior to your application creating it. Item, for example, is created once and shared by many orders.

Pro Tip:
You can save your own order/item ID as originator_id which will make it easier to look up your orders later. Using the Originator ID will also act as a safeguard to prevent your application from creating multiple copies of the same order/item.


We're no longer accepting v1 API connections, but established apps will still work for the foreseeable future. All new connections must be made through our v2 API. 

  1. The v1 API uses standard token authentication using your Customer key. It features limited endpoints.
  2. The v2 API is very comprehensive, and requires Oauth authentication. Request access here.

You may optionally specify which API version you'd like in an X-API-VERSION header. The default API version is currently 1.
New features/endpoints will only be added to the v2 API.

Testing Environment

We provide a testing server at

You can test things out with our shared Sandbox customer account, using authentication key kQmwEGWwPRtzEQzSeCvG, or you can e-mail us for your own test account.
