Prevent API sprawl with an API catalogue

An API catalogue is a crucial tool for managing an organisation's growing inventory of APIs, preventing the chaos of API sprawl by providing a structured, internal library that allows developers to discover and use available APIs efficiently. Unlike a developer portal, which targets specific markets and provides additional documentation, an API catalogue organises all APIs, including those under development, to avoid duplication and enhance reuse. Effective management of an API catalogue involves defining processes for adding new APIs, maintaining URL path conventions, and potentially automating API registration through continuous delivery processes. As organisations aim for "big 'R'" reuse, they often transition to managing an API platform that supports internal and external developers, fostering innovation and integration with partners and customers. A case study in the hospitality industry illustrates the challenges and benefits of implementing an API catalogue, such as improving accessibility and automating deployment, ultimately leading to a more modular and composable API infrastructure that supports diverse developer needs.
