Hello, We are seeking for a solution to integrate with, and we are considering if PlayFab offers what we need. We need a tool to create quests for our games. We have a platform with webgames, with our own backend, authentication through Firebase. We need the solution based on events, for example a user in our game makes 10 games win in a row in a week, that supposed to be marked as quest done in external platform (like yours). We need to pass the information about score in each game. We also want to create events on login each day etc. or reward an user by ref link from webpush notification after opening it. Is this all possible by still keeping our backend on our own? Just to use external event service for achievements on your side?
