Step 1: Set Up Your AWS CDK Project

Step 2: Use the AWS CDK to create an API Gateway REST API with Synchronous Express State Machine backend integration

Step 3: Test the API Gateway

Step 4: Clean Up

package com.myorg;


import software.amazon.awscdk.core.Construct;
import software.amazon.awscdk.core.Stack;
import software.amazon.awscdk.core.StackProps;
import software.amazon.awscdk.services.stepfunctions.Pass;
import software.amazon.awscdk.services.stepfunctions.StateMachine;
import software.amazon.awscdk.services.stepfunctions.StateMachineType;
import software.amazon.awscdk.services.apigateway.StepFunctionsRestApi;

public class StepfunctionsRestApiStack extends Stack {
    public StepfunctionsRestApiStack(final Construct scope, final String id) {
        this(scope, id, null);
    }

    public StepfunctionsRestApiStack(final Construct scope, final String id, final StackProps props) {
        super(scope, id, props);

        Pass machineDefinition = Pass.Builder.create(this, "PassState")
                                .result(Result.fromString("Hello"))
                                .build();
        
        StateMachine stateMachine = StateMachine.Builder.create(this, "MyStateMachine")
                                    .definition(machineDefinition)
                                    .stateMachineType(StateMachineType.EXPRESS)
                                    .build();
                                    
        StepFunctionsRestApi api = StepFunctionsRestApi.Builder.create(this, "StepFunctionsRestApi")
                                   .stateMachine(stateMachine)
                                   .build();
                                   
    }
}
