UPI Intent is an app-to-app redirect flow. The merchant checkout launches the customer's UPI app with payment details prefilled via a deep link. No VPA entry is required. On desktop, the same deep link is rendered as a QR code for scanning. Set payment_method_flow to
redirect
.
UPI Intent is the recommended integration. It improves mobile conversion and enables QR checkout on desktop. NPCI guidelines effective February 2026 restrict manual VPA entry on mobile transactions, making Intent the compliance standard for mobile checkouts.
UPI Intent is the migration target for existing UPI Collect integrations, due to deprecation plans of the latter.

App launch / QR display On mobile, render buttons for specific UPI apps using deeplinks constructed from the deep_link_value. On desktop, render the deep_link_value as a QR code for the customer to scan with their phone.

Recurring payments
Recurring payments up to ₹15,000 per individual transaction are processed without customer intervention. For amounts above ₹15,000 per transaction, an additional authentication factor is required for each debit. These debits are not supported.
Customer receives a notification 24 hours before the scheduled charge.
If the customer declines the follow-up charge, a decline response is returned.
If the customer does not decline the charge, a success response is issued.
When creating the initial payment, specify the amount to be debited for future subscription charges. This amount appears in the customer’s UPI app when the mandate is created. The mandate authorizes follow-up payments.
For example, if the merchant has sold the customer a subscription plan for up to ₹3,000, the customer sees this amount at the time of mandate creation, along with a notice that payments may be up to ₹3,000.
Any payment below the amount specified in the initial request occurs without additional confirmation from the customer. However, the customer still receives notifications the day before the follow-up payment and can cancel the subscription at any time.
Billing periods
The future_usage.billing_period maps to the UPI Autopay mandate frequency. Only the combinations of billing_period.unit and billing_period.value below are accepted.

These rules apply when the billing period is sent directly in future_usage.billing_period and when you use product_id, the product configuration must match the table.
UPI Intent checkout
The
init-payment
API response contains payment_type_data.deep_link_value, a generic UPI mandate URI.
Render the deep_link_value as a QR code. Display logos of supported UPI apps above the QR code. Show a countdown timer reflecting the 15 minute session window. Generate the QR code directly from the URI. Do not use a payment provider's QR generation API.
Render a button for each supported UPI app. Construct app specific deeplinks by replacing the generic
upi://mandate
prefix with an app specific scheme:
UPI app
App specific scheme
GPay
tez://upi/mandate
PhonePe
phonepe://mandate
Paytm
paytmmp://mandate
Example deep links after replacing
upi://mandate
in deep_link_value:
1
tez://upi/mandate?pa=x@bank&am=29900
1
phonepe://mandate?pa=x@bank&am=29900

paytmmp://mandate?pa=x@bank&am=29900
On iOS, the universal UPI app tray does not work due to OS level restrictions. Prepend a per-app URL prefix before opening the deep link. This requires explicit app level handling on the frontend.

Payment Form
Integrate UPI Intent via APM buttons. Payment Form detects the device and renders the Intent flow on mobile or a QR code on desktop. Set upiButtonParams.enabled to
true
to display the button when UPI is enabled for the merchant.
Do not use a payment provider QR generation API. Payment Form generates the QR directly from the Intent deep link returned in payment_type_data.deep_link_value.
Selection at checkout Customer selects UPI on the Payment Form.
App selection Payment Form displays up to 6 to 8 UPI apps. Top apps appear first: Google Pay, PhonePe, Paytm, BHIM. Additional apps are under Show all.
App launch Customer selects an app and is redirected to authenticate and confirm the mandate. On iOS, Payment Form prepends the per app URL prefix before opening the deep link.
Payment result Payment Form receives the result via webhook and transitions to the success or error screen.
Selection at checkout Customer selects UPI on the Payment Form.
QR display Payment Form generates a QR code from the Intent deep link and displays supported UPI app logos above it.
Scan and authorize Customer scans the QR with their UPI app, then authenticates and confirms in the app.
Payment result Payment Form receives the result via webhook and transitions to the success or error screen. If the session expires, the QR is marked expired and the customer is prompted to restart.
