Is there an upload API for Google Photos (photos.google.com)?

Question

Does the Google Photos app, released on May 28, 2015, have an API which allows uploading of photos? The app seems to build on Picassa and Google+. Can one of their APIs can

Answer 1

I figured it out using Fiddler against the Google Photos Uploader and toggling the resolution level back and forth.

If you use the mediaBackground upload, it has a parameter for "storage". If you set the parameter to "standard", it is unlimited quota. If you set it to "full", it is against your quota.

So the API Call for full-res quota photos is:

/resumable/upload/plus/v1whitelisted/mediasets/me.cinstant/mediaBackground?uploadType=resumable&imageSize=1024&mediaType=photo&storage=**full**&remainingMediaCount=111

While the API call for standard-res (up to 16 megapixel) unlimited photos is:

/resumable/upload/plus/v1whitelisted/mediasets/me.cinstant/mediaBackground?uploadType=resumable&imageSize=1024&mediaType=photo&storage=**standard**&remainingMediaCount=111
