API Gateway

OpenAPI

OpenAPI is a powerful specification designed to document and define your API configuration comprehensively. By leveraging OpenAPI, you can streamline your API deployment process with ease.

How OpenAPI Works

When you provide an OpenAPI specification to an API Gateway, the gateway parses the file and automatically sets up all the defined routes. This automation simplifies the task of managing multiple endpoints and ensures consistency throughout your API deployment.

Furthermore, if you create an API using an API Gateway, you have the option to export its OpenAPI specification. This exported document can be shared with your clients, empowering them to generate and integrate API calls seamlessly into their applications.

Note

OpenAPI specifications not only help in the initial setup of your API routes but also serve as a reliable source of truth for future updates and integrations.
