How to integrate UPI in an Android app?

To integrate UPI in an Android app, developers primarily use the UPI Intent flow or a merchant API. This involves:

• Constructing a UPI URI containing the payee virtual address, name, transaction reference, and amount in INR.
• Triggering an Android Intent with ACTION\_VIEW to display a list of installed UPI-enabled applications.
• Handling the transaction response returned to the app to verify success, failure, or pending status.
• Ensuring compliance with NPCI security guidelines, including encrypted communication and secure data handling.

For complex requirements, businesses can partner with sponsor banks for direct API integration.
