Hi,
I am integrating Juspay payment gateway on my site. After user enters credit card details on merchant's site, it hits my return url.
My question After knowing the status of payment is how do I send the user to correct page ?(i.e. Payment failure of successpage).

Write now what I am doing is if payment status is successful I do a db update to change the contribution_status_id to 1 in civicrm_contribution table and redirect users to  'my-site-url/civicrm/contribute/transact?_qf_ThankYou_display=true&qfKey='{$qfKey};

I tried using following -
CRM_Utils_System::url('civicrm/contribute/transact',  "_qf_ThankYou_display=1&qfKey={$qfKey}", false, null, false)
but nothing seems to be working. I am taking help from http://wiki.civicrm.org/confluence/display/CRMDOC/Example+of+creating+a+payment+processor+extension

Anybody has any idea how to process payment gateway response and send users to correct page? What all db queries need to be done?

Any help much much appreciated.

Thanks,
Negi
