UPI integration using deeplinking in iOS

Question

I am working on opening GooglePay, PhonePe or PayTM app when the user taps on Pay via UPI.

According to NPCI docs https://www.npci.org.in/sites/default/files/UPI%20Link

Answer 1

This isn't documented either but the two schemes that you might want to try are:

• tez://upi/*
• gpay://upi/*

If I had to take a guess about which one will be better supported it would be the gpay option.

Update

I've tried and it doesn't look like the URI's I provided above work. See https://internal-absorbed-celsius.glitch.me/
