No experience with ePDQ, but I do use curl to access another online processor (for Direct Debit transactions) via https.
I'm no expert with curl, but in my case on OS X it's actually very simple via 4D (v2004), and only really one call to LEP. Something like this : [In my case I'm sending xml data containing the DD info] C_TEXT($inputStream_t;$errorStream_t;$ShellResults_t;$ClaimCommand_t) $inputStream_t:="" $errorStream_t:="" $ShellResults_t:="" $ClaimCommand_t:="curl -d '<my_xml_goes_here>' https://target_url_goes_here"; LAUNCH EXTERNAL PROCESS($ClaimCommand_t+"\n";$inputStream_t;$ShellResults_t;$errorStream_t) $ShellResults_t contains the results of the call - in my case more XML... Can't remember why I've got the \n after the command :-) HTH John On 2 Feb 2011, at 4:43 pm, David Wright wrote: > Adrian > > I'm trying to do exactly the same thing, without much success. > > You'll find a previous thread, in which Aparajita recommends: >> Call a 4D method that does the post and returns the result.
