Is BaaS suitable for storing/reading Facebook user profiles without explicit (for the user) registration?

Question

Facebook

Good afternoon.
I have never encountered BaaS at all, before delving into the question, I want to ask for advice from knowledgeable people.
There is a mobile application with user authorization through Facebook.
Platforms: Apple iOS, Android
The application is written in C++ and Marmalade SDK.
It is necessary to synchronize profiles between players who are friends on Facebook.
The player profile consists of approximately 40 integers + Name.
At the same time, it is necessary to avoid explicit registration for the user by all means - authorization through Facebook should be enough.
I would like to have the following functionality:
void SaveDataToServer( userID: FBIdOfVasya, userData:"1234567890" );
userData LoadDataFromServer( userID:FBIdOfPetya );
Thanks in advance.
