UPI Testing

WhatsApp Pay

WA-001 Android only

WhatsApp Pay — Standard merchant intent

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.

The control. Every other profile is this one plus something, so a failure here is a failure of the destination or the app, never of an optional field.

Expected

WhatsApp Pay opens on its payment confirmation screen showing the payee and ₹2.00. The control. Every other profile is this one plus something, so a failure here is a failure of the destination or the app, never of an optional field.

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 — WhatsApp Pay publishes no URI scheme the lab is willing to claim. Use the Generic UPI group (GN) on iPhone.
  • On Android: WhatsApp Pay installed (com.whatsapp).

Notes

  • WhatsApp 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 com.whatsapp, with no browser_fallback_url so a failure to open stays visible. iOS: not implemented, because no scheme exists to implement.
