Hey there!
I would like to make it easier for my board of executives to add decals into our database to remotely load them in-game. When putting a number into an image label (gui object), you will see that it changes.
Is there a web api that I can call with the store id (the link from the url to the decal page) and retrieve the asset it? (The number that it changes to)
Thanks a lot in advance! 
Kind regards,
Jonas
There used to be an API that someone created for this purpose but to the looks of it, it’s deprecated:
You could look into F3X’s source code and see how they do it, I am not sure myself though.
Aha, where can I find their source? Though, I believe they will just be using insertservice or margetplaceservice:getproductinfo. I’d need a web api 
Addon: I just tested that endpoint, it still appears to be working!! Hurray! Thanks a lot!
If anyone knows how it is done, let me know. I’m interested in that .
I use MarketplaceService to get the image of the decal. Note this returns a smaller resolution image, but it works.
Thanks! Sadly, I’m looking for a web api 
Found an endpoint that might be of use:
GET api.roblox.com/marketplace/productinfo
Parameters:
assetId | long | The ID of the asset.
Returns:
{
"TargetId": 123456789,
"ProductType": "User Product",
"AssetId": 123456789,
"ProductId": 24870409,
"Name": "Hat",

},

}
Hope I helped
The AssetId key/field matches the ID passed as an argument to GetProductInfo().
