I am implementing a Messenger Bot for a Facebook Instant game. The bot server needs to deliver certain messages to the players at given intervals since they last perform certain actions.
For this, I need to store the last time a player logged in, and perform scheculed calls to get the list of players that should be messaged at that specific time.
I cannot find a way to do this directly with PlayFab, and it feels too overkill to have a separate player database only for this feature.
Can someone please hint what would be the preferred way to do something like this with PlayFab? Thanks.
