first data global gateway API Integration gives error

Question

I have compiled a simple ASP.NET project to test first data global gateway API Integration.

Someone tell me what to do because I have tried everything.

It throws the ERROR if I use ASP.NET Development server:
<r_error> Unable to load certificate   ERRs: wsa=33558530 err=33558530 ssl=537317504 sys=33558530.  INFO: ACE_SSL (5260|6284) error code: 33558530 - error:02001002:lib(2):func(1):reason(2)
</r_error>

ERROR if I use Virtual Directory: This is generated when

//Call LPTxn
string resp = LPTxn.send(keyfile, host, port, outXml);

is done

ERROR: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

Testing On:

Windows 7 ultimate 64 bit

Project at the root have:

default.aspx 
status.aspx
111222333.pem

Bin:

LinkPointTransaction.dll
lpssl.dll
libeay32.lib
libssl32.dll
ssleay32.lib

Web.Config just showing this to make sure:

<client>
      <!-- Change this to your store number -->
      <add key="Configfile" value="xxxxx"/>
      <!-- Change this to the name and location of your certificate file -->
      <add key="Keyfile" value="111222333.pem"/>
      <add key="Host" value="xxx.xxx.net"/>
      <add key="Port" value="1129"/>
</client>

Answer 1

Sorry for the delay in getting back to you. Below is the code I used. In particular take a look at how BuildOrderService sets up the certificate.

Answer 2

1. Check that you properly copied the digital certificate from the merchant's Welcome Email into a .PEM file on the web server. Compare the path to the file with the path and file name you provided to the secure payment gateway.
2. 32bit versus 64bit issues:
   • "An attempt was made to load a program with an incorrect format" even when the platforms are the same
3. Check that the Solution Platform is set to x86 in Visual Studio and compile the application again.
4. Possibly caused by a PEM file that is not able to be processed with the API.
   • Try: make a copy of your existing PEM file and reformat it using notepad. Add line breaks at the 66th character position

Answer 3

If using IIS, go to the application pool that's running the site and open Advanced Settings. There you can set "Enable 32-bit Applications" to true. That should fix your problem.

Answer 4

What trust level is your application using when its deployed to the production server? If it's running in medium trust, its possible it can't access a component required by the DLL. You can replicate this locally by setting your .net trust level for the site to medium. If setting your local site to medium trust reproduces the issue, then you will need to either get your host to enable full trust, find another host that has full trust, or get a VPS.
