Hi @RomanLubushkin do you have the code that is consuming the game flow session???? that needs the theamOne and teamTwo??

[RomanLubushkin]

Hi @f3ar161 Yes, we're using flowSession data to identify summoners, their champions, and assigned roles if any during the game. Based on that info we're getting statistics and analytical data from our end.
