I've been reading more or less every StackOverflow question about Google Photos, and still I haven't figured out the answer.

I need, for my Rails app, to get the url of every single photo uploaded on Google Photos. 

I can't use Picasa for a long term project, G Drive API does not find all the photos, G+ can't find all the photos

Please, help me find a solution O.o It can be Javascript-based, or curl-based, I'll translate it. 

Thanks in advance! 

UPDATE

I've found <https://github.com/howdy39/google-picker-api-demo> which lets me get all my photos inside an album. It's something, but I hope Google will release better Google Photos API soon. :)
