UPI QR Code Generator Widget

Add a UPI payment QR code generator to your website. Enter a UPI ID, the payee name and, if you like, a fixed amount and a note, and the widget draws a code that Google Pay, PhonePe, Paytm, BHIM and other UPI apps open as a ready-filled payment.

How it works

UPI apps understand a payment link of the form upi://pay followed by the payee address (pa), the payee name (pn), an optional amount (am), the currency (cu=INR) and an optional note (tn). The widget checks that the UPI ID has the name@handle shape, that the amount is positive with at most two decimals, and percent-encodes every value so spaces, ampersands and non-English names reach the app intact. It only draws the code: the payer's app shows the name registered with the bank before any money moves, which is why you should always scan your own code once before printing it.

Method

  • Link: upi://pay?pa=<UPI ID>&pn=<payee name>&am=<amount>&cu=INR&tn=<note>
  • Each value is percent-encoded (UTF-8); the @ in the UPI ID is kept as is
  • UPI ID check: letters, digits, dot, dash or underscore, then @, then a handle starting with a letter
  • Amount: optional, greater than 0, at most two decimals; left out so the payer types it
  • Payee name (pn) is required, as the NPCI linking specification marks pa and pn mandatory; note up to 80 characters
  • Values percent-encoded per RFC 3986 (space = %20, not +)

Limitations

  • It makes a person-to-person style request with no merchant code (mc) or transaction reference (tr); registered merchants who need reconciliation should use the dynamic QR from their bank or payment gateway.
  • The UPI ID is checked only for shape; whether it exists and whose name it belongs to is known only to the payer's app, so always scan your own code before sharing.
  • Payment limits are set by NPCI and each bank and change over time; the Rs 1,00,000 warning is a guide, not a check.
  • Currency is always INR - UPI does not carry other currencies in this link.
  • The code cannot confirm that a payment was made; check your bank or UPI app for the credit.

Where publishers use it

  • Small shops, tutors and freelancers showing a payment code on their website or invoice page
  • Temples, NGOs and community groups collecting donations with a fixed or open amount
  • Event pages collecting a fixed entry fee with the booking reference as the note
  • Accounting and billing blogs showing readers how to make a payment QR for their own UPI ID

Questions

Does this widget process payments?

No. It only creates a QR code containing your UPI details. The payment happens entirely inside the payer's UPI app between the two banks; A2Z never sees or handles money.

How do I make sure the code pays the right person?

Scan it with your own UPI app before sharing. The app shows the name registered to the UPI ID - if it is not yours, check the ID for a typo.

Should I set an amount?

Set one for fixed prices such as a fee or a product. Leave it empty for donations or varying bills; the payer then types the amount in their app.

Is there a limit on the amount?

Banks set the limits. Many cap a single UPI payment at Rs 1,00,000, with higher limits for some categories, so the widget warns above that figure.
