Can a sender dispute sending payment?

I am wondering if someone who sends you money can dispute the funds and reverse it back? For example, if I sell something to someone on a site like OfferUp, and they pay me with Apple Pay

The reason I ask is because payment services like Venmo can be scammers and they can reverse the payments by "disputing" them with the payment processor. I want to make sure that someone can't fake a payment to me, take the good, then dispute it and get their money back and keep the goods.
