i thing when test in facebook api graph explorer

{   "error": {     "message": "(#294) ",      "type": "oauthexception",      "code": 294   } } 

what did https://graph.facebook.com/act_my_acc_id , set permission ads_management. happen when test on test code.

your app has whitelisted ads api access.

if app whitelisted, need use valid user access token access ads api endpoints. user has have given app ads_management permission , must have access ads account you're trying access.
