How to create an API monitor using an OpenAPI (Swagger) spec
OpenAPI and Swagger help users design and document APIs in a way that is readable from both humans and machines. As a consequence, they can also be used to generate the code that will run the specified API - both on the provider and consumer side. Can we leverage this same principle to simplify API monitoring? After a brief first look at OpenAPI and Swagger, this article will show how we can quickly use them to monitor a new or existing API.
