This page explains how you can integrate the UPI payment source in your custom checkout solution to instantly collect the total amount payable from your customer with a single identifier i.e. UPI ID or VPA. Users can conveniently use their VPA to make a secure and immediate payment without entering any bank or card details and without using multiple apps (merchant, SMS, UPI app) for payments.
Paytm offers two UPI flow to collect payment on your checkout page:
- UPI Intent
- UPI Collect
Note: If a user wants to make a payment using the UPI payment source, it is mandatory to have the UPI apps installed on their mobile device.
