Coupons not working when payment module is on. Need help Please

I have my Grand Opening today and found out last night about this issue. I have searched to forum for hours and can not find anyone having this issue.

During testing I had my payment module off and the coupons worked fine. As soon as I turn on my Payment Module it will no longer apply the coupon. I do not get the notification that it worked and will not show in the invoice. :frusty:

I'm looking for a fix or workaround. My thought is to move the Discount code entry to it's own page in the checkout process before the cc information is entered. If this is possible How would I do that? Or, Would it be possible to move the Coupon Entry off the same page as the CC information page to the previous page? This way the discount can be added before a customer adds the CC information.

One other thought, could a button be added that will apply the discount without requiring a customer to enter the credit card information first and going to the final conformation page?

Thanks for any help that could be offered.

It would help to know what payment method you're using.

Sorry yes that might help,

It is the "Gateway Processing Services" Module GPS

It is the only module that I have as active all others are disabled.

Edit: payments are through NMI Payment Gateway

I have now lost business over this issue. :please: Please some one help me move this to to page 1 of the checkout or Page 3. My Processing company says they can't help and thee is nothing wrong with the setup, the template is fine and should work because it works offline. If I were better at manipulating code I would do it myself but I'm hesitant to do this for fear of crashing the store. Maybe what I'm asking is not simple but even directions would be helpful. :)

Looking to hire someone to help me fix this issue. I really need to fix this issue and am willing to pay someone that can help me get this working.

If you temporarily turn on Check/Money Order, does the Discount Coupon work?

Ajeh,

Just tested:
If I turn on the Check or Money Order with the Gateway on, It will work as it should.

If I turn on just the Check and MO it works as it should.

Tried just because:
But Just the gateway it won't work.

I am afraid I am not familiar with the "Gateway Processing Services" Module GPS so I really cannot say why it doesn't work alone ...

Do you have the addon that you used for that?

The module is a stand alone file. I don't use any other add on with it.

Now this is odd, I tested the just the gateway first, Now after it worked once with my test profile it is adding the coupon automatically without typing it in. Odd

Oh sorry I misunderstood, Yes I have the add-on file. Would you like me to post the code? Or would it be better to PM the code to you?

Perhaps post just the link to the addon would be helpful ...

That I can't do it is behind my account login. I don't think it has any account info in it because it was with other modules for other carts on their site.

Perhaps you should contact who you got this from and ask them why it isn't working properly with Zen Cart ...

I tried that and they said it was not a problem with their Module. It is still my opinion that it is when everything works fine without it. LOL Can't say much for their customer service on this issue. I really appreciate your help!

I just took a quick look at the files and there is 3. They do have my API key in them so posting them would not be a good idea. I'm sure that is why they were behind my login as well

I am having the same issue and found if I select other pay options, the coupon works. But with the Gateway Processing Services payment module, it doesn't work. Did you find a solution Fadora Vapor?

I figured it out!!! You can't use the GPS module with the coupon codes. I talked to their tech support. The reason is because transaction data is stored at the clients end and passed to GPS, the coupon code is not part of this transaction data. There are two ways around this.

Enable and use the Authorize.net (AIM) module.

1. Find the Authorize.NET module, typically available in: includes/modules/payment/authorizenet_aim.php

2. Make a backup of the file.

3. Open the file and replace 'secure.authorize.net' and 'test.authorize.net' with 'secure.nmi.com' and save the file. Ensure the full URL is: https://secure.nmi.com/gateway/transact.dll
   --- URLS ARE ON 531 AND 532

4. Active the Authorize.NET module from within the ZenCart admin.

5. In place of the API User ID, use the gateway 'username'. In place of the transaction key, use the gateway 'password'

You will have to have your ZenCart Admin setup for SSL for this module to work.

The other option is to move the coupon code box from page 2 of the checkout to page 1. This option is not so easy as it involves Javascripting.

They were more helpful to you than they were for me. I will give this a try over the weekend and see if it works Thank you for the suggestions :D

Did the NMI support team give this solution?

Yes it was NMI. You have to press #3 when you call them to get to their Integration Team. The woman I spoke to was very knowledgeable! Good luck!
