API Portal is a web-based, self-service portal that enables an organization to securely expose APIs to external developers, partners, and other consumers for use in building their own applications on their desired platforms. API portals are bridges between API providers and API consumers that provide information about the API at every stage of an API’S lifecycle. API portals allow providers to expose and publicize their APIs, educate developer communities about them, provision user access, generate client keys and more. For API consumers, API portals are the place to register applications, reset credentials, share and interact with API documentation, provide feedback about the quality of the API and report bugs.
