How to get corresponding google photo ids and google files? - google-api

Question

Users may optionally have their Google Photos show up as a folder in Google Drive. Deleting in Drive deletes in Photos, and vice versa (with exceptions for albums and other gotchas). See https://support.google.com/photos/answer/6156103 for details.
Is it possible to get the correspondence between a Photos mediaItem resource and Drive files resource via the API?
I've already done the naive thing: look for matching and embedded ids in both. No luck. Sample returns from the API are included below. (Ids and URLs were slightly mangled to make them non-functional.)
example mediaItem:

Answer 1

Starting July 10 2019, Google Photos and Google Drive no longer sync, so there no longer is any correspondence between photos in Drive and Photos - they are entirely separate entities.
You can however import photos from Google Drive to Google Photos.
