What are global commands?
Global commands are commands that are used on the action of any item within your shop. So if you set up a global on-purchase command, when any item is purchased within that shopping module, that command will be sent.
How do I use it?
A new global commands section is available in your DonationCraft Settings.
Global commands are a great way to setup a response to charge backs on items or just running common commands on all items.
