I was see Subscriber Id area.This is 15 digit number when i was download sales report from iTunesConnect. I did not match any receipt number and i did not match any kind of information which i have. What is this, How can i use? Is anyone have idea? Can i use this number for matching my subscriber?
Secondly what will happen when i sending a receipt to my server takes error? What should i do. Subscriber Id can help for this situation.
