Explanation

To use one API across multiple environments in API Gateway, you define the API’s routes (HTTP method + path) and attach an integration that invokes your Lambda backend. Then you create separate stages for each environment (for example, dev/test/prod) and use stage variables to dynamically select the correct Lambda target per stage, so the same API definition can point to different environment-specific backends.
