I've got a button setup for redeeming Gift Cards. Server uses our Gift Card redeem button and processes the card but since it's setup as a tender they are able to highlight the Gift Card amount and select adjust and can change the tender to a greater amount without it communicating with our cloud server to take the amount off the card. I've been messing with the Authorization tab under the tender I setup for the GC Redeem but it lets your type anything an to push the tender adjust through. Anyone run in to this before or know how I can lock that tender down so it can't be adjusted manually? Are there security settings to not allow servers to adjust any tenders?
