mobpay - upi gateway using notifications
mobpay is a lightweight, self-hosted alternative to traditional payment gateway aggregators, built for indie developers accepting upi payments without a bank partnership. an android companion app listens for incoming upi payment notifications, extracts the amount and note, and forwards them to the backend to confirm the transaction in real time.
merchants generate a upi qr code per payment request, and can track its status via webhooks or server-sent events all without any third-party payment processor.
