About "Facebook Access Token that has been received after authorization.", you need to integrate tha facebook SDK because when you login with facebook in your app you will get the access token. That is why its called after the authorization.
About your query for UpdateFacebookStatus, you need to call linkUserFacebookAccount first after that you can call the UpdateFacebookStatus function. We can update our documentation for tha same so people can better understand what is right order to use social service.
Also you can work with method which is inbuild in App42 Unity SDK, for that you need to create an app from facebook.
After the success of app creation on facebook you will recieve the facebook appId which you need to pass in below code snipped as input parameter & this will return the facebook accesstoken which you can use for update status or wall post feature : -
string perms = new string;
perms = FBPerms.email;
perms = FBPerms.friends_birthday;
perms = FBPerms.photo_upload;
perms = FBPerms.user_photos;
App42API.BuildSocialService().DoFBOAuthAndGetToken("Facebook_App_Id", perms, true, new UnityCallBack ());
public class UnityCallBack : App42CallBack
public void OnSuccess(object response)
Social social = (Social) response;
public void OnException(Exception e)
