UPI Testing
AZ-004 Android only

Amazon Pay — Category code and note

No mc and tn set, so this is the same payload as the plain control.
Why
Profile P04 is defined by mc and tn, and neither your UPI profile nor this run supplies one — so comparing P04 against P01 would be comparing a method against itself and reading the noise as a finding. Set mc and 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.
Addressing one named app from a browser needs an Android intent URI, and you are not on Android. There is no iOS equivalent for this app.
What would unblock it
Open the lab on an Android phone, or use the Generic UPI (GN) group here.

Whether the note survives the merchant flow. Some apps that show a note in a P2P flow drop it in a merchant one.

Expected

Amazon Pay opens on its payment confirmation screen showing the payee and ₹2.00. Whether the note survives the merchant flow. Some apps that show a note in a P2P flow drop it in a merchant one.

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.
  • On iOS: not addressable — Amazon Pay publishes no URI scheme the lab is willing to claim. Use the Generic UPI group (GN) on iPhone.
  • On Android: Amazon Pay installed (in.amazon.mShop.android.shopping).

Notes

  • Amazon Pay 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.amazon.mShop.android.shopping, with no browser_fallback_url so a failure to open stays visible. iOS: not implemented, because no scheme exists to implement.
