# Things to keep in mind!



> **Note**
> * Please ensure that the UPI QR Code feature is enabled at gateway end.
> * Please ensure that the UPI payment mode is enabled under the respective gateway in Juspay dashboard.

> * If you are not using the Juspay checkout page, please make necessary payload changes mentioned in the Integration documentation following the same syntax.

> 
> If UPI QR flow isn't working, please verify the gateway through which the transaction was processed and confirm whether UPI payment method under the UPI section is enabled on that specific gateway. Additionally, examine for issues related to Priority Logic routing.

### FAQs



## FAQs:

### Can the same UPI QR Code be scanned multiple times ?

Yes, the same UPI QR Code can be scanned multiple times. Consequently, if multiple transactions are done using the same UPI QR Code, Juspay will retain transaction details only for the initial transaction. Subsequent transaction details will be accessible exclusively at the Payment Gateway end.

### How to generate the UPI QR Code image?

UPI QR Code image generation has to be completely handled by the merchant. Once the URI is generated, merchants have to create the UPI QR Code image with the generated URI.

There are several Js libraries that help in generating QR code. 

Sample library : [https://www.npmjs.com/package/qrcode](https://www.npmjs.com/package/qrcode)
