Use ROBLOX's Web API's to get a game icon?

I want to know if you can use the ROBLOX web API's to get a game's icon. Not the thumbnail. By icon I mean the square image that appears when searching the game. Any help is appreciated.

First, you download an image of the roblox square (You just search it up online) then you go to the develop page and go to the place you want to edit. Then, you click on the gear image on the right of the place you want to edit. Next, click configure place and go to the game icon tab. After that, click choose file. Click on the roblox square and press open, right under the choose file button, press upload image and there u go. Please accept my answer if this helped:) ~rilgundam
