UPI Collection API - NxtBanking

26 Feb 2026 · Updated 15 Apr 2026 · 4 min read

What is UPI Collection API?

UPI Collection API enables businesses to programmatically accept payments from customers through Unified Payments Interface (UPI). Instead of sharing bank details or using manual payment links, your application can trigger UPI collect requests, generate QR codes, or create payment links — all through simple API calls.

With over 14 billion UPI transactions processed monthly in India, UPI collection is the fastest-growing payment method for B2B and B2C businesses. NxtBanking UPI Collection API supports all UPI payment flows with 99.99% uptime.

UPI Collection Methods

1. UPI Collect Request

Send a payment request directly to the customer VPA (UPI ID). The customer receives a notification on their UPI app and approves the payment with their PIN.

2. UPI Intent (Deep Link)

Generate a UPI deep link that opens the customer preferred UPI app directly with pre-filled payment details. Highest conversion rate for mobile apps.

3. UPI QR Code (Static & Dynamic)

Generate Static QR codes for fixed amounts or Dynamic QR codes with unique transaction IDs for each payment. QR payments have the highest success rates.

4. Payment Links

Create shareable payment links via SMS, WhatsApp, or email. Customers click and pay through any UPI app.

Quick Answers

What are the main UPI payment flows for businesses?

Businesses can use UPI Intent (customer-initiated via QR scan or payment link), UPI Collect (merchant-initiated payment request to customer's UPI ID), UPI Mandate (customer-authorised recurring auto-debit), and UPI QR (static for counter payments, dynamic for per-transaction amount binding).
