Google Reader API mark as read

Question

I'm trying to mark an item as read using Google reader API.

I'm calling: https://www.google.com/reader/api/0/edit-tag

with POST parameters:

i=tag:google.com,2005:reader/item/abd8ef2540e2948a
a=user/-/state/com.google/read
ac=edit
s=feed/http://9gag.com/rss/site/feed.rss
T=//XyTiEe7pm4RZtwtO2KKTfw

and I get Error 400: Bad Request

any help?

Answer 1

This error is often thrown when your access token(T parameter) is expired. Access token is a short-lived token, it expires after 30 minutes (according to this).

I think you should get a new token and take one more try. I just tried this API method out, and it works.

One more note: your ac=edit parameter is not necessary here. This parameter is used in the subscription API, not in edit tags API. So you can easily remove it.
