The way to do this is to follow the UPI linking specification (page 5).
Assuming that the link will be presented on a mobile web browser, your link should look something like: upi://pay?pa=<VPA>&am=<AMOUNT>

You can integrate the UPI intent solution provided by paytm. This will work fine in mobile view, through this integration you will get the deeplink. You need to call the deeplink provided which will invoke all the UPI PSP Apps on the device and shown to the user with payment amount already filled. Just for your information UPI intent will not work in web/desktop. You can integrate UPI collect to support web/desktop payment.
