Problems with Link Point

Hiya,

Can any Zen geniuses help out a ZC newbie? I've been trying to get my Linkpoint module working on my Zen Cart site, but seem to be stuck with the following error after trying to confirm a test order:

"we are presently unable to contact the Credit Card company for authorization"

I followed the instructions for setup (got the SSL, PEM is installed, port is open):

* LinkPoint or YourPay Account (naturally)
* cURL is required and MUST be compiled into PHP with SSL support
* Port 1129 is used for bidirectional communication with the gateway, so must be open on your host's router
* PEM RSA Key File (Provided by LinkPoint)
* You need to have an SSL certificate active on your site to protect your customers' sensitive data

So I imagine I'm stuck somewhere on curl, but I am not much of a coder so I don't know what I'm looking out for when trying to fix.

Many thanks in advance for your big brains. Mine feels very small right now.

Thx

I replied to your other post with the following questions. Perhaps you can answer them here:

iheartguts:

Having the same problem, also with Link Point.1. Just to clarify, by "having the same problem", do you mean that your checkout "hangs" after clicking Confirm? Or something else?

2. Who's your hosting company?

3. What version of Zen Cart?

4. What addons/contributions have you installed?

5. Are you using the built-in Linkpoint API module, or the older one from the downloads area?

You might try reading this FAQ:
https://www.zen-cart.com/tutorials/index.php?article=298

Also, grab the curltest tool from this thread:
http://www.zen-cart.com/forum/showthread.php?p=408522#post408522

Upload the unzipped php file to your server, and post a link to it.
Also, try running it with your browser. What happens?
Then add ?linkpoint=1 to the URL ... now what happens?

Hi Dr. Byte,

Sorry for posting twice, I thought maybe the other thread was too old.

1. Just to clarify, by "having the same problem", do you mean that your checkout "hangs" after clicking Confirm? Or something else?
   It processes, then gives the following error: we are presently unable to contact the Credit Card company for authorization

2. Who's your hosting company?
   Open Source Host

3. What version of Zen Cart?
   Zen Cart 1.3.7
   Database Patch Level: 1.3.7

4. What addons/contributions have you installed?
   Nothing special that I know of, but I ahve made several modifications to templates and such

5. Are you using the built-in Linkpoint API module, or the older one from the downloads area?
   built-in version

the above is what it looks like with the ?linkpoint=1

this is what it looks like with just the curltest:

What's the URL to your curltest.php ?

Or at least try adding this as an alternate parameter:
?url=https://secure.linkpt.net:1129/LSGSXML

sorry about that, here's the links:

thank you!

Okay - your CURL communications appears to be fine as far as Linkpoint connectivity is concerned.

Let's turn on debug logging to find out what results are coming back from linkpoint:
Go to the Zen Cart Admin edit screen for your Linkpoint module -- click Edit.
Now add &debug=on to the end of the URL in the browser, and press Enter.
Scroll down to the bottom of the list and choose a logging option. Email is easiest in this case, as long as you can access the Store send-from email account as indicated in the Admin->Config->Options screen.

Now try a transaction and post the log details.

Thank you so much for all your help. Here's the log details, with address, etc. removed, of course. Looks like a connection problem, or problem with headers?

thanks again, you absolutely rule.

iheartguts:

unable to use client certificate (no key found or wrong pass phrase?) ErrNo:581. What was the filename of the .pem file you downloaded?

2. What is the store-number value you entered in the ZC admin module settings?
   They need to match.

ah yes, the merchant ID and PEM did not match before and now they do, thank you. i ran a test and get the following error:

should i try running a real test while not in testing mode?

thanks again!

i also got an email confirmation for the order, btw. but when i confirm the order, i get that string of code rather than a confirmation of order. thanks again so much!

That's all good.

Turn off the logging now, so the warnings disappear.

As for doing tests, you should always test real live transactions before opening your store to the public.

By golly, it works! You are a miracle worker, thank you so much. Can I donate to the Zen Cart fund in your honor?

Yes, the site is password protected so no one can place orders until we've fully tested the shopping cart.

YAY!

Glad it's working!

I all of a sudden have the same problem on our site.. Dr. Byte what/where is this option to turn off logging? The orders kick back that same PHP header error as noted above but the order still is successfully charged and noted to the customer via email as well as into zen cart. It just gives a bad impression for someone to see a bunch of php error code when they hit confirm on their order!!

also just to note, in my header error my PEM # and my Merchant ID are correctly the same and always have been.

why in the world would a cart start printing out that debug info after upgrading the cart? I followed your directions and turned it on and off and still the cart is showing the debug printout - it does finalize the sale and linkpoint accepts the charge but checkout-success will not show up.

the printout says debugging = true debug = true

I checked the database and it says false. what gives?

Did you remove and then re-install the module via the Admin interface? There are some changes in the way those settings are handled, and it's necessary to refresh them by removing and reinstalling.
