Develop REST APIs using OpenAPI in API Gateway

You can use API Gateway to import a REST API from an external definition file into API Gateway. Currently, API Gateway supports OpenAPI v2.0 and OpenAPI v3.0 definition files, with exceptions listed in Amazon API Gateway important notes for REST APIs. You can update an API by overwriting it with a new definition, or you can merge a definition with an existing API. You specify the options by using a mode query parameter in the request URL.
