PlayFab Auth Help

[strange zinc]

i think the forum is outdated: https://doc.photonengine.com/realtime/current/reference/playfab

The site i put in my photon custom service https://test.playfabapi.com/photon/authenticate ( i have my ID in the test part )

the authenticate link says

  "resultCode": 3,
  "message": "Failed to parse token from request",
  "userId": null,
  "nickname": null
}``` even though the forum says to do 

lbClient.AuthValues.AddAuthParameter("username", PlayFabUserId);
lbClient.AuthValues.AddAuthParameter("token", PlayFabPhotonToken);```
