Hello, So I'm trying to add a payment gateway for Liberty Reserve to my 4.1.4 developer. I'm listing below all what I did so far & information I gathered (please ask if you want more details), any help or clues appreciated especially that my knowledge in PHP is very limited Editing config.php was rather simple: PHP: <?php $data['gateway']['name'] = "libertyreserve"; $data['gateway']['displayname'] = "Liberty Reserve"; $data['gateway']['showas'] = "Liberty Reserve USD"; $data['gateway']['version'] = "v1"; $data['gateway']['extraTxt'] = "Account Number"; $data['gateway']['extra2Txt'] = "Leave Blank"; $data['gateway']['cconsite'] = 'N'; ?> The N in the end is fine I guess, or better put Y ? Now to the sr.php file, following instructions for SCI on LR website, I edited the forms this way: PHP: function libertyreserve_createForm($params) { $libertyreserveurl="https://sci.libertyreserve.com"; $output = '<form name="final" action="'.$libertyreserveurl.'" method="GET">'; $output.= '<input type="hidden" name="lr_acc" value="'.$params['extra'].'">'; $output.= '<input type="hidden" name="lr_store" value="My Store">'; $output.= '<input type="hidden" name="lr_amnt" value="'.$params['oTotal'].'">'; $output.= '<input type="hidden" name="lr_currency" value="LRUSD">'; return $output; } I tested the form & it works fine but I'm not sure if 68classifieds needs to send more data? Also the bigger headache is getting data back after payment is made. I can add store data in my LR account (whose ID is in the extra field), the interface looks like this: I think my Success URL should be http://domain.com/thanks.php?gateway=libertyreserve is it the same as the Fail URL ? Status URL is the page (or email) that will receive data from LR to allow merchant verify SCI server's data, data contains among other fields, 2 HASH SHA256 strings in fields called lr_encrypted & lr_encrypted2 , for example you can read this about verification via lr_encrypted: OK, I don't have a clue how to implement this in 68, LR offer a sample SCI script you can download from here. I'm attaching to this post the status page I found in that sample. Thanks for your attention!
