how to get qID for applybookmark method

[#1]

Hi

I created a bookmark :

I want to use extension API:

{

  "handle": 1,

  "method": "ApplyBookmark",

  "params": {

  "qId": ""

  }

}

here the qID is needed,  if I put the "Adm2016" :

{

  "handle": 1,

  "method": "ApplyBookmark",

  "params": {

  "qId": "Adm2016"

  }

}

the return is :

{

  "jsonrpc": "2.0",

  "id": 22,

  "result": {

  "qSuccess": false

  }

}

So How can I find out the qID of the bookmarks?

thanks!
