We are setting up some merchant functions
If a customer sends too many coins in a transfer for an order
Can you send the change back to address you received the coins from .
i.e 1) Order 1234 12.5 BTC Merchant Recieve Address (1234abc)
2) Customer Sends 12.6 BTC to Merchant Address (1234abc) from his Address (4567def)
3) Merchant detects overpayment And sends the 0.1 btc back to customers (4567def) Address as change
Will this work in that the customer will get his change ??
