An API manager, sometimes called an API gateway, handles the parts of API integration that get harder to manage as usage grows: authentication, rate limiting, request transformation, logging, and analytics. Rather than building that control layer into every individual integration, IBM i teams route API traffic through a gateway that enforces the same rules everywhere.
Buyers researching IBM i API integration software often start by asking about specific connectors, but the more durable evaluation question is whether the platform includes real API management capability or only point-to-point connections.
