After numerous hours debugging, I figured out what was going wrong.. when SSL is enabled on shopping cart pages, Actinic provides Secpay with HTTPS callbacks – as you’d expect. It also sets a parameter which Secpay needs if the callbacks are HTTPS. However for some reason at this moment in time Secpay won’t use the HTTPS callbacks – the request is never sent to the server

I don’t know why this is happening, I even used the alternative method of informing Secpay that the callback is HTTPS – via the ‘options’ parameter.. no dice

The solution I’m currently using is to modify the ‘OCCSecPayScriptTemplate.pl’ file, inserting a line after the following block of code:

# to enable Diners cards, remove the ‘#’ from the start of the 2 lines below
#$sOptions .= ‘,’ if ($sOptions ne ”);
#$sOptions .= ‘diners=true’;

the line to change the callback URLs back to HTTP is:

$::sCallBackURLAuth =~ s/https/http/;
