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.

Google Pay

GP-002 Not applicable here

Google Pay — With transaction note

No tn set, so this is the same payload as the plain control.
Why
Profile P02 is defined by tn, and neither your UPI profile nor this run supplies one — so comparing P02 against P01 would be comparing a method against itself and reading the noise as a finding. Set tn 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.
You are on a desktop browser, which has no UPI app to open. The URI is still shown and can be copied.
What would unblock it
Open this page on the phone you want to test, or use a QR-scan method (QR group) which is designed for exactly this situation.

Whether a note is displayed, truncated, stripped or rejected. Note length limits differ sharply between apps.

Expected

Google Pay opens on its payment confirmation screen showing the payee and ₹2.00. Whether a note is displayed, truncated, stripped or rejected. Note length limits differ sharply between apps.

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.

Prerequisites

  • A saved UPI profile with a payee address.
  • On iOS: Google Pay installed and registered for tez://upi/pay
  • On Android: Google Pay installed (com.google.android.apps.nbu.paisa.user).

How the lab runs it

Android: an intent:// URI naming com.google.android.apps.nbu.paisa.user, with no browser_fallback_url so a failure to open stays visible. iOS: the tez://upi/pay scheme carrying the same query.
