Why it matters
It is the only way to reach these profiles and results from another device. The lab stores a hash of it, so nobody here can recover it for you.

BHIM

BH-010 Needs your identifiers

BHIM — Bank-issued merchant identifiers

No mid and msid and mtid set, so this is the same payload as the plain control.
Why
Profile P10 is defined by mid and msid and mtid, and neither your UPI profile nor this run supplies one — so comparing P10 against P01 would be comparing a method against itself and reading the noise as a finding. Set mid and msid and mtid on the profile first, or run P01 and know what you measured.
pa — A payment needs a payee address. Nothing can be launched without pa.
Missing mid — values a bank, PSP or acquirer issues and the lab must never invent.
What would unblock it
Needs the merchant / store / terminal identifiers your acquirer actually assigned you. An invented mid is not a merchant identifier, it is a string, and a result against one would be meaningless.

Whether an acquirer-issued merchant triple changes the receiving experience.

Expected

BHIM opens on its payment confirmation screen showing the payee and ₹2.00. Whether an acquirer-issued merchant triple changes the receiving experience.

Limitations

  • A browser cannot tell you whether an app is installed. "App did not open" and "app is not installed" look identical from here; AN-004 in the Android harness is what separates them.
  • Not runnable on iOS at all through this method.

Prerequisites

  • A saved UPI profile with a payee address.
  • Needs the merchant / store / terminal identifiers your acquirer actually assigned you. An invented mid is not a merchant identifier, it is a string, and a result against one would be meaningless.
  • On iOS: not addressable — BHIM publishes no URI scheme the lab is willing to claim. Use the Generic UPI group (GN) on iPhone.
  • On Android: BHIM installed (in.org.npci.upiapp).

Notes

  • BHIM publishes no URI scheme the lab is willing to claim, so it cannot be addressed directly from a non-Android browser.

How the lab runs it

Android: an intent:// URI naming in.org.npci.upiapp, with no browser_fallback_url so a failure to open stays visible. iOS: not implemented, because no scheme exists to implement.
