AWS Marketplace SaaS Product Integration Testing - SNS subscriptions

During the product creation process, you'll receive the actual Amazon Resource Name (ARN) to the SNS topic. For example: arn:aws:sns:us-east-1:123456789012:aws-mp-subscription-notification-PRODUCTCODE [+] and this SNS topic is created by AWS for marketplace notifications automatically. Please note that, the SNS topic is created and managed by AWS marketplace and doesn’t belong to your AWS account. The reason why AWS docs mentions SQS as a potential subscription to the SNS topics created around AWS Marketplace entitlements and subscriptions is because you can subscribe SQS to the SNS topic that was created in the AWS marketplace account because SQS supports cross account subscriptions from SQS console while a Lambda subscription needs to be created from SNS console to which you will not have access as the SNS topic resides in an AWS managed account. Furthermore, as a workaround you can use Lambda to poll SQS for your use case and the message flow will be as follow: SNS -> SQS -> Lambda
