Hi Gabriel,
Thank you very much for your reply.
What I need to do is basically a reward system for offline stores.
The users enters its purchase receipts and win mycred points.
So, according the amount spent on offline stores, this amount will be converted in mycred points.
Therefore, each user must enter its points themselves (here is the help I need to implement it).
I would like to use your lottery add-on to pick a daily/weekly winner(s). I don’t care about fraud attempts because the winner must pickup the prize on physical store, and before to get the prize he need to provide the proof of previous purchase which was used to enter in mycred points.
Do you suggest me a way to do that?
