This input allows you to define actions that can be triggered before and after a pending order is opened. The time they are executed (before or after) is determined by the keyword before the actual action name. As you may already know from previous topics, actions always take the a:
prefix. When you set actions using this prefix they will always be executed after the opening of the pending order. In order to set the action to be triggered before the opening event, you have to use the prefix a_before:
instead.
