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

When an AWS::Serverless::StateMachine is specified, AWS Serverless Application Model (AWS SAM) generates an AWS::StepFunctions::StateMachine base CloudFormation resource.

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

Role property is not specified

When the Role property of an AWS::Serverless::StateMachine is not specified, AWS SAM generates an AWS::IAM::Role CloudFormation resource.

An API event source is specified

When the Event property of an AWS::Serverless::StateMachine is set to Api, but the RestApiId property is not specified, AWS SAM generates the AWS::ApiGateway::RestApi CloudFormation resource.

An event bridge (or event bus) event source is specified

When the Event property of an AWS::Serverless::StateMachine is set to one of the event bridge (or event bus) types, AWS SAM generates the AWS::Events::Rule CloudFormation resource. This applies to the following types: EventBridgeRule, Schedule, and CloudWatchEvents.
