Hi Nishit please find some comments below:

a) it looks like you were fixing #6622 Pin filed with “0” and removed its value at all, today we’ve got a complain that clients receiving activated numbers notifications with no PIN at all please see screen shot below:

just to clarify when admin removes pin there should not be any thing in the pin field but in all othre cases customers should see their pins.

b) there were some numbers orders it says API but no numbers on the order could you please have a look at that as well;
