AWS::ApiGatewayV2::ApiMapping

The AWS::ApiGatewayV2::ApiMapping resource contains an API mapping. An API mapping relates a path of your custom domain name to a stage of your API. A custom domain name can have multiple API mappings, but the paths can't overlap. A custom domain can map only to APIs of the same protocol type. For more information, see CreateApiMapping in the Amazon API Gateway V2 API Reference.
