Getting Version ID when generating product keys after an order

Im following the following tutorial http://wyday.com/limelm/help/how-to-generate-product-keys-after-order/ and trying to set some values in the CSharp example of WebAPI. In this example, I need to set the version ID in the fin-key.aspx.cs file.

The step 4 of the above tutorial states: "You can get the version ID by examining the URL in your browser. For instance, from the URL http://wyday.com/limelm/version/100/ you can see the version ID is 100".

But my URL is l http://ocalhost/Web_API. Im sure I am missing something. Where in my web app do I need to click to get the URL in the format http://ocalhost/Web_API/limelm/version/versionID where versionID would be some number that I can use to set the version ID? Thanks.
