Dear community, I have been stuck with this problem for quite sometime, I have been trying to use the upload api and have tried the example specified on the page. And I've been getting the error: badtoken and info: invalid token. I couldn't get it to work. I have followed the said steps. First get the token. The result was as follows. {"query":{"normalized":[{"from":"Test_Page","to":"Test Page"}],"pages":{"2":{"pageid":2,"ns":0,"title":"Test Page","touched":"2012-06-05T16:09:33Z","lastrevid":2,"counter":3,"length":12,"new":"","starttimestamp":"2012-06-15T14:43:02Z","edittoken":"a25a10589a377fc4d75e5e0dcfb209c2+\\"}}}} Then tried uploading the file. $params = array( 'action' => 'upload', 'url' => 'http://www.google.com/intl/en_ALL/images/logo.gif', 'token' => "a25a10589a377fc4d75e5e0dcfb209c2%2B%5C", 'format' => 'json' ); I keep getting the error as follows. {"error":{"code":"badtoken","info":"Invalid token"}} Where is it that I am going wrong ? -- Regards, Suryajith Chillara.
