This is Version 1 of the UltraCart REST API. It is now legacy. It will remain forever, but no new development will be done.

Please see Version 2 for new development.

Version 2 Supplemental Documentaion

Introduction (Things you'll wish you read first)

The UltraCart REST API aims to be a lightweight protocol for tying a checkout page(s) to the UltraCart back end.

// this code was removed due to incompatibility with the current UltraCart engine.

Every call needs a merchant id (our merchant id is DEMO). We need to know who you are. There are four ways to provide the merchant id to the server:

Use your StoreFront url instead of secure.ultracart.com within your proxy script.
Query Parameter: _mid=DEMO
HTTP Header: 'X-UC-Merchant-Id': 'DEMO'
Cookie named UltraCartMerchantId

The very best way is to use your StoreFront url. Every merchant has free StoreFronts with their account. Make sure you have one configured with a valid theme, and then change your proxy script to point to your StoreFront url. For example, change the destination from secure.ultracart.com to <MerchantID>.ultracartstore.com. Any requests directed to a StoreFront will automatically resolve the merchant id automatically.

Most of the examples below use the http header since it's easy to use with jQuery. If you wished to do it for all your ajax calls, you could execute this javascript:

jQuery.ajaxSetup({ cache: false, headers: {'X-UC-Merchant-Id': 'DEMO', "cache-control": "no-cache"});

However, that makes each call less atomic (and jQuery doesn't recommend it). Still, it's an option and make work well with your site.

If you receive an error "Missing Merchant ID", you've forgotten to do one of the above.

Now, in case you're wondering why the three methods use different names...

We made the query parameter as short as possible to keep the urls as short as possible. We used an underscore to denote "meta data" to the call.
We follow common practices for naming custom http headers. While the X- prefix is officially out of vogue, we still think it looks cool.
The cookie 'UltraCartMerchantId' is used in hundred of existing UltraCart checkout pages. So it made sense to stick with that cookie name.

When something doesn't work or you get an error, open your browser console and view the headers. Look for the error.

then fix it.

Can't? Then get on github.com. Ask for help.

Object Model

Any json objects referenced below may be found on the Checkout REST API screen. These two APIs have lots of overlap.

Site REST API

The site rest api deals with calls that are more merchant-centric rather than cart-centric. They usually return information that is the same regardless of the cart, such as a merchant's return policy or allowed countries.

When a site rest call does take a cart, it's to augment the call with customer specific information.

For example, if a merchant has pricing tiers configured, then the prices for items will be different if a customer is logged in or not. Those calls that take cart objects will consider the logged in user when returning back pricing, etc.

You'll see this behavior on some of the item calls.

When a call takes an optional cart object, the method type will usually change from a 'get' to a 'post', and the post payload will be the cart's json. Don't forget to set the right type if you're passing in the cart.

/rest/site/stateProvinces

Method	GET	Comments
Description	returns back all states for the country provided	This is a convenience function to retrieve all configured states for a country. It just avoids having to hard code a bunch of states in an application. If you're just shipping to the US, this call doesn't make sense. However, if you ship internationally, this call can be very handy to populate a state/province field with the correct values dynamically whenever the country field changes from (example) United States to Canada.
