New to Square. Can a price modification, through applying a discount, be performed via Orders API when the order is created via the Ppoint of Sale application. The doc says that Order Update cannot be performed in such a case yet, but what about applying a discount? Thank you.
An order that is created on the Point of Sale application is only available via API once its fully paid for. At that time its no longe able to be updated. We’re constantly working to improve our features based on feedback like this, so I’ll be sure to share your request to the API product team. 
Thank you for your quick reply and forwarding it to the API product team, Bryan. I hope we’ll see that feature at some point as it would open up some exciting possibilities.
