We've added some new functionality to our Rest API. You can now use a vendor as a parameter when retrieving inventory. This is especially useful if you want to compare your stock for a vendor vs. their data feeds, especially when your vendors don't include out of stock products in their feed.
The second addition allows you to see the costs of your items and your bundled items when retrieving order information. This is particularly helpful when you’re using the API to import orders into an accounting system that tracks COGS.
