I have one question though; how would I retrieve a list of read posts? I’ve tried using the reading-list and can get it to return all unread posts, but not all read ones.

Any help would be much appreciated.

olkbbcnw…

Using the web-based Google Reader interface, i can either open a feed for *real* reading, or just “mark it as read” (using the “mark all as read” function).

The difference it seems between these 2, is how it is refkected in the Trends. Items that are actually opened for reading are counted as “Items Read”, while items that are just “marked as read” are not.

In terms of the API, how are these 2 actions differentiated? (Because, what i understand is that to mark an item as read is to add a “read” state to the item, or is there a different way?)

Thanks!

Great article. However, I can’t seem to get Item Editing EDIT-TAG to work. I always get a 401. I am using C#. Do you have any code that is working?

Thanks.

There are ways to get the items that belong to a particular group/folder/tag/label, and you can check the item data to find out all the groups it belongs to, but… how can you tell which feed belongs to which folder? Considering that the viewer UI for Google Reader lets you sort feeds into folders, there should be a way to do this, shouldn’t there?

Is there a way to either get the folders that a feed belongs to, or to get a list of feeds that belong to a folder?

This is my code, it works normally until 2010/01/, but after that date, it always return error 401.The SID and token are all right.

who can help me? Thank you first!
