This tutorial will walk through a common use case for the Kong Gateway Key Authentication plugin: using API key authentication to protect a route to an API server endpoint. Install Kong Gateway: Set up a Node.js Express API server with a single endpoint. (0:30) Set up Kong Gateway to sit in front of an upstream service: our API server. (2:30) Set up the Key Authentication plugin to protect the route by requiring a valid API key in the request header. If the user provides no key, they’ll receive a 401 Unauthorized response. (7:30) Use Kong to create a consumer (a valid user) and a credential (an API key). (10:30) Demonstrate that a request through Kong—if it includes a valid API key—is forwarded to our API server. (11:55)
