]
}
}

In the above screenshot I had taken a snapshot of fields.. If I have have different payment methods they all have different fields for credit card option..

My issue is here that I need these field parameters related to every payment method dynamically using rest api magento 2.

Api available in magento is only providing me payment method name.. I do not want to send my choice parameters in json but I need dynamically which are provided by the payment gateways?

Anyone can help..

Did you figure this out? I also need to know how to get to the payment method params to be able to call authorize.net payment method via api. Thanks.
