Answer: Using DefinitionSubstitutions for the AWS::StepFunctions::StateMachine to include the API endpoint.
The correct answer is A. This approach leverages CloudFormation's DefinitionSubstitutions property for the AWS::StepFunctions::StateMachine resource, allowing for the dynamic insertion of the API Gateway endpoint. This method is cost-effective because it utilizes native CloudFormation capabilities without requiring additional services or resources. Options B, C, and D involve storing the API endpoint in separate services (environment variables, Secrets Manager, or AppConfig), which adds unnecessary complexity and costs.
