Simple calculator API OpenAPI definition - Amazon API Gateway

Simple calculator API OpenAPI definition

The following is the OpenAPI definition of the simple calculator API. You can import it into your account. However, you need to reset the resource-based permissions on the Lambda function after the import. To do so, re-select the Lambda function that you created in your account from the Integration Request in the API Gateway console. This will cause the API Gateway console to reset the required permissions. Alternatively, you can use AWS Command Line Interface for Lambda command of add-permission.
