is there a REST API to create a Data Source?

[Dave Oshinsky]

My ultimate goal is to be able to use Import Set API to import data from JSON to an existing Target table, doing this in a program using REST API's. The Import Set API is available as a REST API, but a prerequisite for importing to a Target table is to first create a Staging table. In another Developer form thread on the subject of creating a Staging table, one reply was that creating a Data Source automatically creates a Staging table.  Is there a REST API to create a Data Source?

I've asked in separate threads whether there is a REST API to clone an existing table, to create a new table, and now I'm narrowing the question down to creating a Staging table for Import Set API. It seems that many of these operations are intended for manual operation via the Service Now web UI, but a number of these operations do not have well documented (or perhaps any) REST API to allow running the operation from a program.

I don't think it's the best practice to directly create an import set. However you could create this with a few GlideRecords and a custom Scripted REST api. In this scripted REST api you can write any GlideRecord logic you require.

Similar services such as Salesforce have extensive API sets that allow programs to import data to an instance, without the need for a human to sit at a web browser to configure the import or prerequisites of the import. It seems that Service Now has a REST API (Import Set API) to perform the import itself, but not to setup for the import (such as creation of Staging table, or Data Source). I see that Script REST API involves a human sitting at a web browser to configure the REST API extension. Is there a way for a program to run a script (provided by the program) via REST API?
