I'm trying to integrate with the Payroll API and the documentation is a bit lacking. I've managed to setup the Postman collection as per: https://developer.intuit.com/app/developer/qbo/docs/workflows/integrate-with-payroll-api/get-started

I have the normal API collection along with normal auth working, but for Payroll I can't create an Auth token because my Sandbox company does not have Payroll enabled (it gives me an error that the payroll scope isn't supported because payroll is not enabled).

I can't enable Payroll on my Sandbox company (it just fails to load the page) and the docs do mention that there is currently no sandbox support for Payroll.

Which means I have to test using production data (which is Ok since I only really want to integrate with our own company), but it looks like I need to publish the app first so that it can be installed by the company. Which I can't do since I can't test anything.

Is there a way to install/link an unpublished app to a production company so that I can at least test the code? Or some other way to test integrating with the payroll API so I can see if the information I need is available.
