I dont mind making my own research as to how they would go about creating their API.
Sure this might take a while to do so but with enough dedication I might be able to crack down on how everything would work.
theres a way simpler solution to this u can make a dev product in the donation game fr tht ytber and then make a small button prompting the donator to buy it and the donation is done as simple as tht
After looking, you can get a list of owners of an asset (ie. T-Shirt) using Roblox’s API https://inventory.roblox.com/docs#!/Assets/get_v2_assets_assetId_owners
You would have to set something up that checks that endpoint every now and then to see who has it, and if someone who wasn’t there has it, it’ll display it somehow. The only issue is that you have to be the owner of the asset or the API won’t work. Hope this helps
I prefer using Developer Products to then trigger the Post event.
After a bit of research I found that Streamlabs as an API that works with Javascript.
With some offsite coding I can basically make all of this work.
