Resolve UPI/Google Pay Payment Errors
Summary
Freelancer Client is hiring: Resolve UPI/Google Pay Payment Errors.
Location: Remote
I need an experienced mobile-payments troubleshooter to look into my UPI and Google Pay flows. Right now every attempt to pay stalls during the processing phase and simply throws a generic “Something went wrong” type message, so I have no error code to go on.
The task is to trace what’s blocking the transaction pipeline, implement a clean fix, and verify that payments complete all the way through confirmation on both UPI and Google Pay. If you’ve previously debugged PSP integrations, handled server-to-UPI callbacks, or tuned Google Pay API parameters, you’ll probably recognise the pattern faster than I can explain it.
Root-cause analysis with a short summary of where the failure sits (client app, gateway, or backend).
Patch or configuration change applied.
Proof of two successful live transactions per platform.
Skills: PHP, Mobile App Development, Android, MySQL, Debugging, Payment Gateway Integration, API Integration, Payment Processing
Budget: $8000–$18000 USD
