title: AWS CloudFormation API GatewayV2 Route Creation
body: <p>I am creating a template to create an http api with <code>apigatewayv2</code>.</p>
  
  <p>My API definition in template is:</p>
  
  <pre><code>sfHttpApi:
      Type: AWS::ApiGatewayV2::Api
      DependsOn: sfLambdaFunction
      Properties:
        Name: !Sub sfHttpAPI-${Region}-${Env}
        ProtocolType: HTTP
        Target: !Sub arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/arn:aws:lambda:${AWS::Region}:${AWS::AccountId}:function:${sfLambdaFunction}/invocations
        CredentialsArn: !GetAtt sfApiGatewayRole.Arn
  
    sfApiTriggerLambdaPermission:
      Type: "AWS::Lambda::Permission"
      Properties:
        Action: lambda:InvokeFunction
        FunctionName: !GetAtt sfLambdaFunction.Arn
        Principal: apigateway.amazonaws.com
        SourceArn: !Sub 'arn:${AWS::Partition}:execute-api:${AWS::Region}:${AWS::AccountId}:${sfHttpApi}/' 
  
    sfApiLambdProxyIntegration:
      Type: "AWS::ApiGatewayV2::Integration"
      Properties:
        Description: Lambda Integration
        ConnectionType: INTERNET
        IntegrationMethod: POST
        IntegrationUri: !Sub  "arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${sfLambdaFunction.Arn}/invocations"
        PayloadFormatVersion: '1.0'
        ApiId: !Ref sfHttpApi
        IntegrationType: AWS_PROXY
  
    sfRoute:
      Type: 'AWS::ApiGatewayV2::Route'
      DependsOn:
        - sfApiLambdProxyIntegration
      Properties:
        ApiId: !Ref sfHttpApi
        RouteKey: 'POST/'  **??? This is the part I dont know how to set**
        AuthorizationType: NONE
        Target: !Join 
          - /
          - - integrations
            - !Ref sfApiLambdProxyIntegration
  </code></pre>
  
  <p>I tried in different way to set routekey in route definition but getting error while creating the stack:</p>
  
  <blockquote>
    <p>The provided route key is not formatted properly for HTTP protocol.
    Format should be " /" or "$default"
    (Service: AmazonApiGatewayV2; Status Code: 400; Error Code:
    BadRequestException; Request ID: 53198c85-fc41-4c76-89c4-7d2db7a7a5b6)</p>
  </blockquote>
  
  <p>How can I set the routekey?</p>
