HSBC CPI integration with PHP

Having a lot of trouble with this...

[vincevincevince]

Hi,

I've not had experience with HSBC CPI before, and am trying to integrate a shopping cart with it.

The server is Linux/Apache, and I have coded the cart in PHP. I'm desperately hoping that someone can give me a few pointers on what to do here, especially regarding the POST statements.

does your host run php in safe mode?

Does the file 'libCcCpitools.so' have to be installed in my WEB-INF/lib folder or the servers /lib folder?
Can the TestHash.e file live anywhere? Ive put mine in the cgi-bin folder.

I cant seem to execute the TestHash.e file plus it doesnt report an error.
<?
$path='/home/virtual/site66/fst/var/www/cgi-bin';
$cmd="$path/TestHash.e CPIHASHKEY $str";
$ret=exec($cmd);
$ret=split(':',$ret);
//Returns the hash
$hash=trim($ret[1]);
return $hash;
?>

I have tested whether the file exists in its path and it does.

Please help.

Hi guys,

I finally got the TestHash.e working. The problem was that I was passing a junk encrypted key as the argument. But I wasn't getting an error message either. I had to check the exit status with the system() function to get to the root of the problem. Anyway thanx everyone for the help. First hurdle is over, now moving onto the next one :)

Hi luigi_uk,

libCcCpiTools.so has to be put in /usr/lib on the server.

And make sure "TestHash.e" has execute permissions(chmod 755) and it has to be uploaded in binary mode(via ftp)

Also I hope you are not making the same mistake as I did that is you need to pass the actual CPIHASHKEY to TestHash.e and not any junk value.

Hi guys,
I'm going through this same process with HSBC. I've got as far as sending the details to the cpi servlet but every time I just get bounced back to my return page with a Cpi Code of 4 which according to their integration pack means the server gave no response.
Incidentally, nothing is getting sent to the results url either.

Has anyone come across this yet?

Hi Rossriley,

Are you through with the generation of the Order Hash Key?
Check that there could be a problem in the generation.

[rossriley]

Yes i've got the hash generation working ok.
HSBC are returning immediately to my return url with their POST which includes an order hash and the CpiResultsCode. This code is always 4
I can verify their returned order hash and it is fine, just this error code which doesn't really explain anything.

Have u made sure that you're sending the timestamp in ms?

ie

$timestamp=time();
$timestamp*=1000;

[rossriley]

Thanks ajimenez
That was it, i wasn't multiplying by 1000!
Was i glad to see the hsbc site!

"Was i glad to see the hsbc site!"

:) Same here, I've never been so pleased to see a web page. It took me a few days to get the POST sending all of the correct values to the servlet. It's not helped by poor documentation and a lack of support for people approaching this using a scripting language.
