question

I passed none - there wasn't anything actually written about CatalogVersion in the API docs: only that it was optional, and that the example was "5". But I still don't know how it's directly relevant.

I see a starred catalog - I assume this is the "primary".

How do I determine the catalog version? I thought I already chose both the item and from what catalog it came from when I generated the coupons:

In the example it said "5" - is this an index?

If this is an index, would this be version "2"?

I'm still a bit confused about the versions since I thought it's already tied to the coupon - if you could explain it more I'd appreciate it :)

Those (Plate Armor, Cloth Armor, etc.) actually are the versions of your catalog. In short, the original design of the system was that all a game's items would be in a single catalog version, which could be named whatever you want. As you release new versions of your game, you could then version the catalog as well - the fact that the API methods use the primary catalog was specifically designed for this, so that you could just change the primary catalog and have everything automatically switch to the new version. The stores were designed as the way to have logical subsets of the catalog items.

Since many people are using the catalog the way you are (multiple catalogs in a game), we'll be addressing this in a future update, so that we make a cleaner path for people to use them in that manner.

var json = {
                
    "CouponCode" : LastSubmittedKey,
    CatalogVersion : "Game"
};

Ah so "Game" is actually my CatalogVersion? Ahh... I would've never guessed ;) Thanks for that. I'll give it a shot.

Yes, whenever you create a new catalog, you are asked for a unique identifier - the Game Manager asks for a "Name", for instance. That is always used as the Catalog Version for the specific catalog.
