Understanding UPI Architecture

Before exploring into integration, it's important to understand how UPI works:

1. UPI ID: A unique virtual address (e.g., username@bankname) that acts as a financial address for the user.

2. PSP (Payment Service Provider): Banks and non-bank entities that provide UPI services.

3. NPCI (National Payments Corporation of India): The organization that developed and manages UPI.

4. Merchant: Your app, which will initiate and receive UPI payments.

 

The basic flow of a UPI transaction is:

1. Merchant initiates a payment request.

2. User authorizes the payment through their UPI app.

3. NPCI routes the transaction between banks.

4. Banks process the transaction.

5. Confirmation is sent back through the chain to the merchant and user
