About the Add to Cart API About the Add to Cart API Thank you for using Shopatron's Add to Cart! The Add to Cart web service makes it easy to add Shopatron ecommerce capabilities to your site. With Add to Cart, you can: 1. Place Add to Cart buttons on your site s product pages. The Add to Cart widget sends product data to a Shopatron cart. When a consumer clicks an Add to Cart button, your system makes an API call to add that product to the consumer s Shopatron shopping cart, at the correct price and quantity, with the specified options. 2. Add a Quick Cart view and icon to the header of your website. The Quick Cart retrieves the consumer s current cart contents from Shopatron. It displays cart information on the web page, and will update when the cart contents change. 3. Add a Shopatron shopping cart to your website. The shopping cart gets the HTML cart from Shopatron. Shopping cart data may be provided in a rendered HTML format that can be embedded into the central area of a shopping cart page, or it may be in a raw-data JSON format that can be formatted to create a cart page. Finally, in its simplest form, the shopping cart data may be provided as a standard Shopatron shopping cart. The shopping cart area may be fully hosted by Shopatron or it may be hosted by your company. 4. Process your orders in Shopatron! NOTE: This document is for clients who manage their product data in Shopatron. A separate document (available late 2012) will describe how to use Add to Cart if you manage your products elsewhere. Related Documentation This document describes how to use JavaScript to add shopping cart functionality to your web pages. If you don t need a high level of flexibility and control and are looking for a simpler process, you can use XML instead. For details, see Using the Add to Cart API with XML Guide.

Before You Modify Your Web Pages If you are seeking greater flexibility, see the JSON for Add to Cart User s Guide and the Add to Cart Developer's Guide. Before You Modify Your Web Pages Get your API key Before you can use the Add to Cart API on your own site, you must acquire an API key. This key gives you access to the API and identifies your site. Call Shopatron Merchant Support at (877) 715-7467 or email mss@shopatron.com to get your API key. Load the JavaScript library Before you can modify any page, you must load our JavaScript library. The process for loading the library is the same for every page. Simply add the following code to the <head> tag of the HTML for every page you modify. Replace xmvhrhuw with the API key you received from Shopatron. <script id="shopatroncart" src="http://mediacdn.shopatron.com/media/js/product/shopatronapi-2.2.0.min.js" type="text/javascript">{"apikey":"xmvhrhuw"}</script> <script src="http://mediacdn.shopatron.com/media/js/product/shopatronjst- 2.2.0.min.js" type="text/javascript"></script Include default styling If you are not styling the Add to Cart button, quick cart view, and shopping cart, add the following code to the <head> tag for each page you modify: <link rel="stylesheet" href="http://mediacdn.shopatron.com/media/css/product/shopatronjst-2.0.min.css" type="text/css" /> Want to Try It Out?
