Make a UPI payment QR code for an amount

Generate a QR code that any UPI app can scan to pay a set amount to your UPI ID, or a upi://pay link for a button on mobile.

A UPI QR code is a upi://pay link drawn as a QR code. Any UPI app (Google Pay, PhonePe, Paytm, BHIM and the banks' own apps) can scan it and fill in the payee, the amount and a note.

The QR code

The endpoint returns the image, so it goes straight into an <img> tag:

<img
  src="https://api.dharun.dev/v1/upi-qr?pa=shop@okaxis&pn=Sri%20Murugan%20Stores&am=250&tn=Order%2042"
  alt="Scan to pay ₹250 to Sri Murugan Stores" width="256" height="256">

Parameter	Meaning
`pa`	Your UPI ID (required)
`pn`	The name the payer's app shows
`am`	The amount in rupees; leave it out to let the payer type it
`tn`	A note, such as an order number
`tr`	Your own reference for the payment

Add format=png&size=512 for a PNG, which most printing tools prefer.

A pay button on mobile

On a phone, scanning your own screen is impossible, so offer the link itself. format=json returns it:

curl "https://api.dharun.dev/v1/upi-qr?pa=shop@okaxis&pn=Sri%20Murugan%20Stores&am=250&tn=Order%2042&format=json"

{
  "data": {
    "link": "upi://pay?pa=shop@okaxis&pn=Sri%20Murugan%20Stores&am=250.00&cu=INR&tn=Order%2042",
    "payeeAddress": "shop@okaxis",
    "payeeName": "Sri Murugan Stores",
    "amount": "250.00"
  }
}

<a href="upi://pay?pa=shop@okaxis&pn=Sri%20Murugan%20Stores&am=250.00&cu=INR&tn=Order%2042">Pay ₹250 with UPI</a>

Good to know

Nothing is checked with a bank. A mistyped UPI ID still makes a QR code; the payer's app finds out when it tries to pay. Test with a small amount first.
A QR code does not tell you that someone paid. Confirm payments in your bank or payment gateway, using tr or tn to match them.
Payment details you send are never logged, and the images are marked so shared caches do not keep them.
