facebook ads api is not working
===

My campaign is running on FB and I want to extract daily data with the help of Ads API.

I'm using facebook ads api and I'm facing this problem every time 

    {
       "error": {
          "message": "(#294) Managing advertisements requires the extended permission ads_management, and a participating API key",
          "type": "OAuthException",
          "code": 294
       }
    }



I have created one apps XYZ and using this created campaign.
 
With **Graph API Explorer** I generated **Access Token.** and I give permissions also.

What is the problem I dn't know. :(
