I followed the steps on generating token and session id.

I think there's some issue with the expiry time. The second I generate the token and get a session id, I get this error: But using guest session works fine.

401 Unauthorized

{
  "status_code": 17,
  "status_message": "Session denied."
}

This was the generated token. Based on my timezone, I generated this at Jan 13, 2017 1:54 AM.

{
  "success": true,
  "expires_at": "2017-01-12 18:53:37 UTC",
  "request_token": "30864276f2d176226ba872bcda22d9872d14007e"
}
