I have integrated ccavenue payment gateway in my site, on which user redirect to ccavenue.com to fill the form (it can be autofilled) and select the payment option.
But I don't want to redirect users to ccavenue to fill that form and select payment option. Instead I want user can select payment option from my site and redirect directly to that banks interface on behalf on ccavenue.
for example site mobikwik has this type of integration.
