What Does "ebay License Number" Mean?

We had previously tried to set up the ebay add on when we purchased it from CS but that did not work out because we couldn’t get it to communicate. Well, I’m back at trying to torture myself again and couldn’t get to the point of putting all the my information in. The problem is I can’t figure out where to find the “eBay license number” at the very top that it is asking for. Previously I believe this was where you put the license number that came direct from CS-Cart but according to Imac this is something we get from ebay now. So I was wondering if anyone who is trying to use the “included” ebay function in version 4.2.1 figured out where the “eBay license number” is on the ebay developer site.

I found instructions for version 4.1.? here:

CS-Cart Documentation — CS-Cart 4.16.x documentation

…but it does not appear to be for version 4.2?

I have all of the other information:




…but again, I am just not seeing the ebay license number they are referring to.
