I wrote a script which I think is supposed to tag a page with a URL. I copied the URL which SharePoint uses to tag a page with "I Like It" when someone clicks on the I like it button.

The URL is "_vti_bin/socialdatainternalservice.json/AddQuickTag"



        type: "POST",
        url: "/_vti_bin/socialdatainternalservice.json/AddQuickTag",
        data: '{"targetPage":"http://url/calendar.aspx","title":"Documents - All Documents","quickTagId":0}',
        contentType: "application/json",
        success: function(msg){


      return false; 

The script does not work and the error in the logs says "Request format is unrecognized for URL unexpectedly ending in '/AddQuickTag'."

Any Ideas? Is it possible to write such a script?


I would recommend creating your own web service for this. As you probably seen "socialdatainternalservice.json" contains the word "internal".


I would user Fiddler to compare the POST requests.

One using the standard method and one using your script. See if you spot any differences.

  • Thanks for the tip. I found nothing special, but I did find that the standard method is sending a request digest. Right now, I am trying to add a tag using the API. – i.jk Sep 13 '10 at 19:31
