Sadly, purchaseInfo doesn’t return its Asset Icon ID. Please just re-check what it returns here: MarketplaceService.ProcessReceipt
You indeed have to fetch the ProductInfo from MarketPlaceService. @Wildcutepenguin, just try my solution out in case you missed it out.
Yeah, my confused mind.
Don’t forget to add the RemoteEvent though.
Just so everyone is on the same page, this is what my script looks like. currently*
local MarketplaceService = game:GetService("MarketplaceService")
local GetProductInfo = MarketplaceService.GetProductInfo
local debounce = false
game.ReplicatedStorage.SendText.OnServerEvent:Connect(function(player, box, text)
box.Text = text
end)
MarketplaceService.ProcessReceipt = function(purchaseInfo)
local plr = game:GetService("Players"):GetPlayerByUserId(purchaseInfo.PlayerId)
if purchaseInfo.ProductId == 1167909680 and debounce == false then
debounce = true
print("24 HOUR ADVERT bought.")
local ID = tonumber(plr.PlayerGui.AdGui.Frame.TextBox.Text)
local success, response = pcall(function()
return MarketplaceService:GetProductInfo(ID)
end)
if success then
game.Workspace.AdvertBoard.SurfaceGui.Frame.Template.Image = "rbxassetid://"..ID
else
warn(response)
end
wait(1)
debounce = false
elseif purchaseInfo.ProductId == 1167909777 and debounce == false then
debounce = true
print("THREE DAY ADVERT bought.")
wait(1)
debounce = false
elseif purchaseInfo.ProductId == 1167909888 and debounce == false then
debounce = true
print("30 DAY ADVERT bought.")
wait(1)
debounce = false
end
return Enum.ProductPurchaseDecision.PurchaseGranted
end
This only works for decals, not thumbnails of clothing or games.
@ProBaturay @0V_ex @Brickman808
Sorry for the late response. Try this
local ID = tonumber(plr.PlayerGui.AdGui.Frame.TextBox.Text)
local asset
local success, response = pcall(function()
asset = MarketplaceService:GetProductInfo(ID)
end)
if success then
game.Workspace.AdvertBoard.SurfaceGui.Frame.Template.Image = asset.IconImageAssetId
else
warn(response)
end
That’s ok but the script still doesn’t work. 
Instead
"rbxassetid://" .. asset.IconImageAssetId
Yes! We have a solution finally.
It only works on games, is there any way for it to work for clothing too?
What do you mean by clothing? Are you trying to dress a body up?
No, I just want them to be able to advertise games, shirts and pants.
