unique request identificator - prevents duplicate action (e.g. import of an order) The submission ID should be unique string that helps preventing duplication of imported data, sending multiple notifications for single action and so on. In distributed load-balanced environment this might be caused not just only by you calling API multiple times by error, but also by system failover that might occur automatically under high load. You are responsible for generating it in determinate yet unique way for a single source entity/action.
