How do I bypass the payment method selection (dispatcher) page?

[webarton]

Hello, is there anyone who has Worldpay payment process and has bypassed the payment method selection (dispatcher) page?

 

I found this page in Worldpay support. It says I can bypass paymentType parameter.

The page is here.

 

But I've been wondering how I can do it.

 

Could anyone give me some advice?

 

Regards,
