Taking Payment through OfferUp

Hello everyone, I apologize if this is the wrong place to post this. I sold something today and the buyer suggested I used the OfferUp payment system. I hadn’t heard of it and only use the app when I’m moving so people usually just pay in cash. I went through the prompt in the messaging system and the buyer said that her payment went through on her end, however I have no notifications of that. How can I tell if the payment went through?

Did you accept any offers from the buyer? If so, you should see a prompt to meet up or ship. When you meet up or ship, it'll change the transactions bar at the top of your offers page to pending.
