I am new to sticker packs for iMessage and I searched through Apple documents but could not find answer.
For example, I have launched a sticker pack for iMessage app. If user has purchased that sticker pack, in my separate app, I want to award him some points if he has already purchased and installed a sticker pack. Is there a way I can programatically check if a particular user has purchased it in my separate app?
Thanks in advance,
