I have to write a python script with which I should be able list other protected buckets owned by other people who are ready grand access. For this I created a project and enabled Google Cloud Storage in my Google API console, then I installed gsutil and stored 'my credentials' in '.boto' file. now I have to list metadata of all buckets where I have access. My question is what I or other buckets owners has to do to grant access to me/my project so that my script can list metadata of all buckets/object inside bucket?
I'm following this doc for python scripting: https://developers.google.com/storage/docs/gspythonlibrary
