title: Shopify API: Create a Promotion?
body: <p>Using the Shopify API, is there a way to creation promotions for your store?  If not, is there a way to programmatically create promotions in Shopify? (short of using CURL posts to the admin)</p>
  
  <p>That is, I can create a promotion by hand using the admin and navigating to the <code>Promotions</code> and clicking the <code>Add a discount code</code> link.  I'd like to be able to do the same thing programmatically, or to know for certain this isn't possible.  I don't see any obvious method on the <a href="http://api.shopify.com/" rel="nofollow noreferrer">api list</a>, but it seems like something should be an API method.</p>
