Regarding Google Photos API change from March 15:
Can the new API retrieve a link to an album? (To an album the api has created)
Browserlink would be enought, view only access. (Source: )
The old API could retreive a link that gave permissions to ad media and to make comments. This is removed for sure.
I would ask a developer to create an automation instead where my user upload the media via google forms to a drive folder and all images in that drive folder are automaticaly uploaded to a corsponding google photos album.
But even then I still need a link I can send to my clients, enabling them to view the album. I am not sure if this is removed as well?
