Listing not going live after payment

Hi,
I posted this a while ago on the forum but never found a solution to my problem.
if listings are paid for through the Payfast gateway, the listing will be displayed in the listing manager but listings must be manually published.
How can i make the listings go live after payment is made. (payment reflect in my Payfast account and on the credit card account as a payment to Payfast)
I changed the settings on the Listing setup page several times and also changed with the link for the Page and button links. Currently I have it set to link to the Post new listing page as the Call back button makes the listing go live without making a payment.
