Any suggestions on a configuration page within NetSuite for an external application? 1. We have full control of the application 2. We'd like to control the configuration from NetSuite as we have end-users defining a list of configuration entries My first thought is a custom record, but that seems a bit overkill as it will only be one record. Is there a better record/type to use for storing this single configuration? If using the record approach, I suppose we could use it as snapshots. The record will primarily contain mappings between lists

We have been using the custom record approach for Setup Records with integrations. You need to persist/store your mapping somewhere, so the custom record will allow you this. Unless you want to store this on files into the file cabinet.

@eminero I think the "file" approach can be used with a custom form/html display. But it's likely easier to go the custom record approach. It's easy to document internally to say "don't create a new one, because if you do, we won't do anything with it"

In our case, we set in script parameters the setup record id to be used, in that way you can have multiple instances connecting to different environments (keys/tokens) or mappings like your case scenario, this is just for testing purposes, as long as you set the value to be used, you would be fine.

good idea
