How to use gateway only for particular payment mode?

[anand-bhagat]

I want to accept payment through UPI only. But actually I am not getting UPI option others are visible as show in the attached screenshot

. So I read Paytm documentation and I got to know that by sending a parameter enablePaymentMode I can allow the particular channel only as show here https://developer.paytm.com/docs/initiate-transaction-api/ . But I am not able to send that parameter.

@anand-bhagat As mentioned in the documentation this package works on PHP SDK, which is different then API.
The link that you have shared is an API and not a part of PHP SDK.
Currently PHP SDK does not allow to choose payment methods as no such options exists to do according to the official docs.
Better use Paytm API for it.
