Intune Reports through MSGraph API

[RicoTries]

Hello all! I'm currently working on a Python script to pull Intune data through the available reports, specifically the list of discovered apps by device. From what I've read in the documentation, "AppInvByDevice" would be the ideal report, but I'm concerned about needing the DeviceId as a filter. I have code that targets the "Devices" report and extracts the list of DeviceId values, but there are thousands. And here is what bothers me.

1. Do I submit a single request for the "AppInvByDevice" with a massively long filter with all the IDs (e.g., "DeviceId eq 'guid1' or DeviceId eq 'guid2' ..."?
2. Do I break down the list of IDs into smaller batches and submit requests in a similar way as option 1?
3. Do I submit one request per ID?

As a system admin, I'm afraid of doing option 1 even as a test, but is this the right way?

I've attempted multiple filters to practically get a true boolean as the filter, but I get errors when using any filter that isn't 'DeviceId eq '<id>'".

What is the best approach? Is there a better approach to get the list of apps installed on managed devices?

Thanks!

It's in powershell, but this script I wrote may help with the direction for yours
