Would an Integration copied from Production to Release Preview have the same Consumer Token & Secret? I'm not seeing an option to reset those tokens within the RP UI. TIA!

happened to be looking at just the help page you need: https://system.netsuite.com/app/help/helpcenter.nl?fid=section_4254975694.html

Note: Tokens created using the Token-based Authentication feature in your NetSuite production account are not copied to your Release Preview or to your sandbox accounts. To test this feature in Release Preview or in a sandbox, you must create new tokens in that account. Each time the sandbox is refreshed, you must create new tokens in the sandbox.

Thanks @David B this is exactly what I needed!

You do seem to lose the ability to reset the client ID and client secret after a sandbox refresh. I haven't got my 2022.1 RP yet, but I would expect it to be the same (not being able to reset the credentials). However, I found more info that implies production integrations that are still active after a sandbox refresh (IMO also RP accounts) Sandbox Refresh Impact on Integration Records

After every sandbox refresh, review the list of integration records, and block those you do not plan to use, because after the refresh all production integration records are copied to your sandbox accounts, including the production settings.
