I've almost finished integrating Barclaycards ePDQ CPI but im having some problems with the responses, the manual says "4. Handling Transaction Response Messages & returning customers
Once a transaction has been processed, the CPI will post the following parameters back to the Post URL:
• transactionstatus – The outcome of the authorisation request.
• oid – The Order ID value.
a few more things....etc"

However the only thing posted back to my POST URL page is the oid. Has anyone else used this system and found a way of getting transactionstatus to return back to your site too?
