# Things to keep in mind!



> **Note**
> * Please ensure that the UPI Intent feature is enabled at gateway end.
> * Please ensure that the UPI payment mode is enabled under the respective gateway in Juspay dashboard.
> * Merchants should only use live credentials for testing the UPI pay flow in the Juspay Sandbox as well.
> * If you are not using the Juspay checkout page, please make necessary payload changes mentioned in the Integration documentation following the same syntax.



> **Error**
> **UPI is enabled, but the UPI intent flow isn't working. What should I do?** 
> 
> If the UPI intent flow isn't working, please verify the gateway through which the transaction was processed and confirm whether the UPI payment method under the UPI section is enabled on that specific gateway. Additionally, examine for issues related to Priority Logic routing.
> 
> **Is the URI link not invoking the PSP app?** 
> 
> Please recheck the URI link generated and verify if the syntax is correct.




### FAQs



## FAQs:

### What should be done in the event of absent parameters within the SDK parameters received as a response?

Kindly generate the intent URI dynamically ie, based on the params received in the sdk_params response.

### Can we make the same android generic implementation for iOS?

By default, it would invoke whatsapp payment option.

### Can we hardcode apps on Andorid?

Yes, you can use the android package names to create specific URI links. But as per the latest NPCI guidelines, we should not promote or restrict any specific apps.
