What is the correct syntax for Swagger 2.0 AWS requestParameters for MessageAttributes ? to map them from body to header

Question

I'm not familiar enough with AWS to verify whether the syntax for mapping requestParameters is correct for AWS Swagger 2.0 config. The message will be send to SQS with a body like this

{
    "QueueUrl": "https://sqs.us-east-1.amazonaws.com/177715257436/MyQueue/",
    "MessageBody": "This is a test message",
    "MessageAttributes": {
        "EndpointURL": {
            "DataType": "String",
            "Value": "my_attribute_value_1"
        }
    }
}

I have the next config for Swagger 2.0. The main thing here is requestParameters, where MessageAttributes.EndpointURL.Value is remmapped to -> "method.request.header.EndpointURL". I expect to receive this value in EndpointURL Header for my method. Also, I set a default value for this Header(EndpointURL) with endpoint path value.

 /test:
    post:
      consumes:
        - "application/json"
      parameters:
        - name: EndpointURL
          in: header
          type: string
          default: '/test'
      produces:
        - "application/json"
      responses:
        200:
          description: "200 response"
          schema:
            $ref: "#/definitions/TestDto"
      x-amazon-apigateway-integration:
        credentials: "{{RoleARN}}"
        uri: "uri"
        responses:
          default:
            statusCode: "200"
        requestParameters:
          integration.request.body.MessageBody: "method.request.body.MessageBody"
          integration.request.body.MessageAttributes.EndpointAddress.Value: "method.request.header.EndpointURL"
        passthroughBehavior: "when_no_match"
        httpMethod: "POST"
        type: "aws"

Next question

1 Can anyone verify/check whether this is correct syntax for remapping values from integration.request.body.MessageAttributes to method.request.header.EndpointURL. ?

2 If it's correct I expect to receive this Header value in a method for SQS Listener.

@SqsListener(value = "${messaging.service-queue-url}")
public void onMessage(String message, @Header("EndpointURL") String endpointUrl) {
}
