AWS CloudFormation resources generated when AWS::Serverless::HttpApi is specified

When an AWS::Serverless::HttpApi is specified, AWS Serverless Application Model (AWS SAM) generates an AWS::ApiGatewayV2::Api base AWS CloudFormation resource.

AWS::ApiGatewayV2::Api

LogicalId: <httpapi‑LogicalId>

Referenceable property: N/A (you must use the LogicalId to reference this AWS CloudFormation resource)

In addition to this AWS CloudFormation resource, when AWS::Serverless::HttpApi is specified, AWS SAM also generates AWS CloudFormation resources for the following scenarios:

StageName property is specified

When the StageName property of an AWS::Serverless::HttpApi is specified, AWS SAM generates the AWS::ApiGatewayV2::Stage AWS CloudFormation resource.

AWS::ApiGatewayV2::Stage

LogicalId: <httpapi‑LogicalId><stage‑name>Stage

<stage‑name> is the string that the StageName property is set to. For example, if you set StageName to Gamma, the LogicalId is: MyHttpApiGammaStage.

Referenceable property: <httpapi‑LogicalId>.Stage

StageName property is not specified

When the StageName property of an AWS::Serverless::HttpApi is not specified, AWS SAM generates the AWS::ApiGatewayV2::Stage AWS CloudFormation resource.

AWS::ApiGatewayV2::Stage

LogicalId: <httpapi‑LogicalId>ApiGatewayDefaultStage

Referenceable property: <httpapi‑LogicalId>.Stage

DomainName property is specified

When the DomainName property of the Domain property of an AWS::Serverless::HttpApi is specified, AWS SAM generates the AWS::ApiGatewayV2::DomainName AWS CloudFormation resource.

AWS::ApiGatewayV2::DomainName

LogicalId: ApiGatewayDomainNameV2<sha>

<sha> is a unique hash value that is generated when the stack is created. For example, ApiGatewayDomainNameV2926eeb5ff1.

Referenceable property: <httpapi‑LogicalId>.DomainName
