Anyone using RF Smart with Netsuite? How do I access RF Smart data via API/SuiteQL?

RF-Smart has a ton of tables. I've had to dissect what some of them do over the years but there is no shortcut. Look in the custom records for anything starting with rfs or rf-smart and then cross reference into the records catalog. There are a lot of obfuscated table relationships you will need to learn about as well.

Thanks I was able to find the data I was looking for in one of the tables. Now I want to add data on behalf of RF smart. Is that also something I can do?

Sure. Some of the records aren't available in the UI so you have to use code or a workflow.

Do you mean I need to write SuiteScript for this? Is it possible via REST API ?

Oh, I forgot your context. I suppose it could be. do the custom records appear in the rest catalog?

Yeah I can see that in the response of metadata catalog endpoint

I think you should be able to as long as your integration role has access to the custom record
