📃Introduction

A detailed walkthrough of the flow of payments happening on One UPI.

  • One UPI library acts as a mediator between your app and UPI apps (which are already installed in user devices).

  • Our library is based on these specifications provided by NPCI (National Payments Corporation of India).

  • This library is based on Android Intent based operations and Blockchain validation.

  • Whenever payment is initiated, it simply sends the Intent to the UPI apps installed on device.

  • When transaction is done, response is returned from library.

  • Payment will be only processed when payee is having a valid merchant account of UPI. Otherwise, payment won’t be successful. We have designed the code such to reduce the clutter of payment notes in your ledger book. Note: This won’t work for general UPI payee user.
