My website want to accept Ethereum as payment

Initially I want to use Binance Pay, but because I don't have a company, Binance rejected my application.

So now I want to integrate my own payment receiving end, but I don't know where to start.

I can give customer my wallet address and let them send ETH in, but then I have no way to verify which transaction belongs to which user.

I guess that's why exchanges give every user a specific deposit address and automatically collect fund from them. Any idea how to do it? Or maybe there are other ways I can receive ETH from my website users?
