Alternatives to AWS SQS (Access Key) Routes

We’d like to set up an AWS SQS Route, but our infrastructure has moved away from IAM keys and secrets for external access. Is it possible to get an AWS Account ID that we can use set fine-grained security rules that will only allow the Blues Notehub AWS account to send messages into our queue?

We will review this request.
We use AWS’ fine-grained security rules internally so we understand your desire.
