Things created by AWS IoT automatically

Question

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?

"Automatically" means you can look at the following steps:

1. When do you want to create a thing automatically? What is that triggers that create-thing process?
2. Check this link for Just In Time registration of the devices
3. You can create a Lambda function mapped to the AWS API Gateway which can invoke the AWS-IOT SDK to create a thing.
4. Look at this page where they have created 50+ things using Javascript using aws-sdk library using serverless architecture approach
