API Support

Is there any way we can receive a response when the user actually accepts the showfeedpostbox native popup shown when making the api call? We have a Quest in our game that requires the player from sharing the game and in exchange they receive a reward. We currently are giving away the reward just by clicking in the game the "Share" option, because we found no way of stating an "onSuccess" function or something like that.

Could you help us out here? Thanks!
