Connecting to backend using unity

I have a bunch of questions about my website accessibility by unity which runs on a free domain in infinityfree
i want to use it to connect to my mysql databases and save game data in there and i was wondering if all this is even possible in infinityfree
it would be a big help if u provide guidance
thanks a bunch

Not possible.

Take note

thanks a bunch for the quick reply
i will try connecting to web and let web handle the requests

That also won’t work. InfinityFree is a webhosting provider, not an API or storage provider.
