I am wondering how one creates many "things" in the AWS IoT solution via API without using the AWS web interface since this is not realistic in case I want thousands or millions of things. I guess you could write some script utilizing the "aws" client described here "http://docs.aws.amazon.com/iot/latest/developerguide/thing-registry.html" but thats not optimal if I want to control it from another service.
I assumed there would be a RESTish API to do this but it doesn't seem like it if I read the docs: "You use the AWS IoT console or the AWS CLI to interact with the registry."
Anyone who created thousands/millions of things - how did you interact with AWS IoT?
