How to tell if ID is a Facebook App or User

I have a page that is using Open Graph and FBML to put a Like and Send button on my page. The client has provided me with two "User IDs" per my request; however, when I submit them in the fb:admins meta tag and use it against the Facebook debug, I get the following error Too many app ids specified, despite not providing a fb:app_id meta tag.

My question is simple, how do开发者_运维知识库 I determine whether an ID provided is a user ID or an app ID?

another way is to query the obj ID with a param metadata=1,

e.g. query 123213121232131229?metadata=1&fields=id

in the returned metadata, check for the value in "type" field

Try adding them to the Facebook graph URL and check the results: https://graph.facebook.com/?ids=XXXXXXX,YYYYYYYY where XXXXXXX and YYYYYYYY are the IDs, example:

https://graph.facebook.com/?ids=579187142,40796308305

Querying my ID and Coca-Cola's page id would return:

   "579187142": {
      "id": "579187142",
      "name": "Ibrahim Faour",

Coca-Cola was introduced in 1886, patented in 1887, registered as a trademark in 1893 and by 1895 it was being sold in every state and territory in the United States. In 1899, The Coca-Cola Company began franchised bottling operations in the United States.\n\nCoca-Cola might owe its origins to the United States, but its popularity has made it truly universal. Today, you can find Coca-Cola in virtually every part of the world.",

And query a single id:
