I\'m developing an app that accepts Payment using UPI, as per the guidelines provided by the NPCI documentation available at link https://www.npci.org.in/sites/all/t
According to this article there are big differences between Google Pay in India and rest of the world, so if you want to handle requests from India and rest of the world without Google Pay installed (or if there are other problems with opening upi URL scheme) you need to determine from where payment is initiated. For India solution from AtulParmar should work, and for other places try to use guide from article mentioned above. Native web view may, but not necessarily will help. Good luck!
