The AWS JavaScript SDK (and presumably SDKs for other langauges) are dynamically configured from JSON files that specify all the possible API endpoints and their request/response structure for the given service.

In the case of Amazon Personalize, the minimal documentation only describes how to "load" these JSON files for the CLI SDK:

https://docs.aws.amazon.com/personalize/latest/dg/aws-personalize-set-up-aws-cli.html

Here is an example of how to configure a service client object in the JavaScript SDK. I arrived at this conclusion by exploring the node_modules/aws_sdk directory, specifically the apis, and clients subdirectory.

(Download the service models from the page linked above.)
