Worldpay in APEX - issues and experiences

Question

Hi, I am looking into the feasibility of integrating worldpay payment processing to a future APEX app. I was wondering if this is entirely possible and generally trouble free? I would be interested in hearing about anyone who has experience doing this, with possible issues to be aware of. Thanks for any input.

Hi,
This is great feedback, the flexible parameter passing worked a treat, although im running into another issue, which I would be extremely grateful for assistance with.
I am using the procedure below:
PROCEDURE process_wp_payment_response(name_array in owa.vc_arr, value_array in owa.vc_arr)
IS
pieces utl_http.html_pieces;
v_payment_cancel_url varchar2(500) := 'url here';
v_payment_ok_url varchar2(500) := 'url here';
FUNCTION getValForName(p_name in varchar2) RETURN varchar2
IS
BEGIN
FOR x IN 1 .. name_array.count LOOP
IF upper(name_array(x)) = upper(p_name) THEN
RETURN value_array(x);
END IF;
END LOOP;
RETURN null;
END;
BEGIN
IF upper(getValForName('transStatus')) = 'Y' THEN
--generate http request for page & get the data
v_payment_ok_url := v_payment_ok_url || getValForName('M_apex_sess_id');
pieces := utl_http.request_pieces(v_payment_ok_url);
FOR i in 1 .. pieces.count loop
htp.p(pieces(i));
END LOOP;
ELSIF upper(getValForName('transStatus')) = 'C' THEN
v_payment_cancel_url := v_payment_cancel_url || getValForName('M_apex_sess_id');
pieces := utl_http.request_pieces(v_payment_cancel_url);
FOR i in 1 .. pieces.count loop
htp.p(pieces(i));
END LOOP;
END IF;
END;
The idea being that the apex session id is added, and we can the populate some items on the feedback page. This thing is, I am getting a 404 error from the callback, which means that the callback goes to the worldpay default page.
The 404 error only occurs when I use an apex url. When I test it with http://www.google.com for instance, I dont get a 404. If i simply htp.p the url, and copy-paste it into the address line, the page loads fine.
It looks to be something to do with utl_http.request_pieces with apex pages.
