Hi, I am new to the eBay developer SDK. I am trying to find out if there are any special rules, functions, category IDs that I need to follow or utilize to accomplish selling automobiles and trucks. I tried to find the category ID for Automobiles, but was unsuccessful. I also tried to find an example that shows how to sell cars... but also could not find one. Can someone help me out with a small example on the function calls and category ID to use? I am not sure if the SDK selling functions are the same for selling automobiles. Thank you in advance.
