How Do People Track UGC Limited Copies?

I would like to implement this in my game, but I do not know how to:

You just need to use the catalog API. In your game, you’d do this using HttpService every X amount of time.

To get the total copies and the copies sold, you can use https://catalog.roblox.com/v1/catalog/items/{ASSETID}/details?itemType=Asset. It will return something like this:

{
    "expectedSellerId": 0,
    "owned": false,
    "isPurchasable": false,
    "id": 12345,
    "itemType": "Asset",
    "assetType": 8,
    "name": "Example",
    "description": "example.",
    "genres": [
        "All"
    ],
    "itemRestrictions": [
        "Collectible"
    ],
    "creatorHasVerifiedBadge": false,
    "creatorType": "Group",
    "creatorTargetId": 12345,
    "creatorName": "group name",
    "price": 0,
    "lowestPrice": 30,
    "lowestResalePrice": 30,
    "unitsAvailableForConsumption": 76,
    "favoriteCount": 12345,
    "offSaleDeadline": null,
    "collectibleItemId": "173a9e38-e594",
    "totalQuantity": 12345,
    "saleLocationType": "ExperiencesDevApiOnly",
    "hasResellers": true,
    "quantityLimitPerUser": 1
}

Then you can parse totalQuantity for the total number of copies, and unitsAvailableForConsumption for the number of copies that are still available.

If you’re wondering how to get all the other info (resellers, rap, copies, etc.) about UGC limiteds, I wrote a detailed explanation on the required endpoints here.
