I'm looking to integrate a payment feature into my application, and the process involves adding funds to a wallet within the application before proceeding with other transactions.
In your experience, which approach would be easier to implement?
1. Initiating a UPI payment by tapping on a UPI application, triggering a request to the respective UPI application.
2. Generating a QR code for payment.
3. Exploring any alternative method that doesn't involve using a payment gateway.
What are your thoughts on these options?
