Capturing file changes with Google Drive SDK

Question

Honest to say, I haven't been able to deeply look inside the Google Drive API so far but I wonder if the API has support for what I need. I would like to capture changes under a specific folder and notify the users which has access to that folder.

For example, I have a folder named Foo and there are three people who have access to that folder. When Person 1 makes a notable change (uploads a file, changes a file, deletes a file, etc) under that folder, I would like to notify the Person 2 and Person 3.

Please note here that these changes can be done from anywhere, not just from my client. The person can take the action through the Google Drive web interface or the user might be syncing his/her computer with the Google Drive.

The only part I cannot visualize in my head is how to capture the changes under a specific folder.

For the record, I will be using .NET for my client.

Answer 1

What you're looking for is the changes feed in our just-launched Drive SDK v2. However, the changes feed does not yet support retrieving changes for just a specific folder. Instead, it gives all changes to a user's entire Drive. This is a feature request that we're considering implementing, but I don't have a timeline as to when we'll implement this yet.
