I found from Brendan that there is no friend request option available in PlayFab and we can never expect in the future as PlayFab don't work on - Friends, in game chat etc. But now I wanted to know can we use execute cloud scripts in the update function of PlayFab or no. As per my knowledge we cannot as there are limits to the cloud scripts calls. If so how/which part of the code can I notify the receiver of the friend request using cloud scripts and SharedGroupData which was showcased in the slideshare - advanced cloud scripts.
