Definition & Explanation

A freight forwarder is integrating a new customs system interface, but the live authority API has not yet been released for external access. This is the typical use case for API stubbing: a lightweight, pre-configured module stands in for the real external interface, returning fixed, realistic responses to defined requests. Unlike broader API simulation, a stub focuses on a small set of hard-coded response scenarios rather than a full behavioral model. IT providers and logistics companies rely on stubs to build and validate integration logic without touching production systems or generating unwanted traffic against live customs infrastructure.
