Getting App Access Token for facebook

Question

I'm trying to generate app access token for facebook. I used the below request for generating the app access token.

http://graph.facebook.com/endpoint?key=value&access_token=app_id|app_secret

But I'm getting below error.

{
   "error": {
      "message": "(#803) Some of the aliases you requested do not exist: endpoint",
      "type": "OAuthException",
      "code": 803,
      "fbtrace_id": "GX983WVEz1Y"
   }
}

But when I copied The app is and app_secret in App Token Tool, It gave me the access token. But when I tried to generate it by sending the request, it throws above error.

Also, Do I need to add anything here:

key=value

Do I need to add client credential as a key?. Is it beacuse of this I'm getting this error?

Answer 1

Corrected my answer: https://graph.facebook.com/oauth/access_token?grant_type=client_credentials&client_id=YOUR_APP_ID&client_secret=YOUR_APP_SECRET

It worked for me.
