Get list of all files in Google Photos

My ultimate goal is to get a list with all the files (photos, videos) in my Google Photos account preferably with their path. enter image description here

If I have to use some API I would rather use a .NET based one. Can you provide some directions in this matter?

I've tried the Gdata API, via the PicasaService, but providing my email/password as credentials did not work and I always get 404 response.

    How to list all files in your Google Photos:

    I was surprised at how long it took me to find this API. It's not necessarily "secret information", but I suppose most users are perfectly happy viewing their Google Photos "the old fashioned way". My initial goal was to be able to determine which photos had/had not properly uploaded before I risk deleting anything as valuable as even my "3rd backup copy" of old photos.

    Short Answer: (The "Easy" Way)

    1. Make sure you're logged into your Google Account on your "usual" (default) browser.

    2. Click this:   https://picasaweb.google.com/data/feed/api/user/default

    You'll get a text-based list of all your Google Photos Albums. Both the album list and the photo list look suspiciously like RSS Feeds (and can be bookmarked as such if you should so desire).

    I know you don't want to copy your list of photos manually, but I suspect others that come across this question want the "easy" way:

    Authentication: For the sake of simplicty, first make sure you are signed in to your Google account from any Google page, such as from the top-right corner of the Google Search page. This will allow you to use the generic addresses listed below -- otherwise the word "default" would need to be replaced with your Google ID, as as well as other changes to accomodate Google API Authentication.

    API Endpoints

    If you have a preferred method of sending GET requests then all you'll need is two URL's.

    As I understand it, all Google Photos are stored in Albums (even if they don't appear to be). Therefore, in order to list all photos, you must parse all of your albums, listing the photos in each one.

    The GET call to list your Google Photos albums is:

    https://picasaweb.google.com/data/feed/api/user/default

    The GET call to list all photos within an album is:

    https://picasaweb.google.com/data/feed/api/user/default/albumid/__[albumID]__

    Retrieving the List Programmatically: (The ".NET API" Way)

    .NET Example from Google:

    PhotoQuery query = new PhotoQuery(PicasaQuery.CreatePicasaUri(username, albumid));

PicasaFeed feed = service.Query(query);

foreach (PicasaEntry entry in feed.Entries)
{
    Console.WriteLine(entry.Title.Text);
}

    ★ The string "default" can be used in place of a real username, in which case the server will use the username of the current user credentials used to authenticate the request.

    List all Google Photos using VBA: (The"Web-Scrapey Way" with Excel)

    Excel has built-in XML-Parsing functionality, in various forms:

    ...but not even the newest features seem to support enough [of what I assume to be] variations in XML style/source, to be of use to me... (or maybe I'm just doing something wrong.

    Thus, my preferred method for parsing XML is to simply load it into a String with an HttpRequest and then use Instr and Mid to locate the values I'm interested in. It's messy, but I've used it as a "quick fix" to retrieve several types of data from several types of sites.

    While writing this answer I seem to have misplaced my related code (side effect of over-multitasking?!) -- but if you made it this far, you probably get the gist of it. The simple function for retrieving the source from a URL is below. If you're interested in seeing the rest, add a comment and I'll look harder. :-)

    Public Function getHTTP(ByVal url As String) As String
'equivalent to Excel's WEBSERVICE function
    Dim encResp() As Byte, xmlHTTP As Object
    Set xmlHTTP = CreateObject("MSXML2.XMLHTTP") 'create XML/HTTP object
    xmlHTTP.Open "GET", url, False 'initialize GET request
    xmlHTTP.send 'send request to remote server
    encResp = xmlHTTP.responseBody 'receive raw (encoded) response
    Set xmlHTTP = Nothing 'always clean up after yourself!
    getHTTP = StrConv(encResp, vbUnicode) 'return decoded response
End Function

    Also a sneaky way to quickly count occurrences of one string within another:

    Function countOccur(searchWithin As String, toFind As String) As String
    'returns the count of occurrences of [toFind] within [searchWithin]
    countOccur = UBound(Split(searchWithin, toFind))
End Function

    Counting occurrences of <entry> on an album or photo page returns the count of albums or photos on that page.
