AUTHNET: AIM payment notifications not sending

-- HikaShop version -- : 2.6.3
-- Joomla version -- : 3.5.1
-- PHP version -- : 5.4.23

Whne we use PayPal hikashop sends notifications from hikashop normally, but when we switch to Authorize.net using the AIM method, no notifications come from the store themselves, they come from Authorize.net and the client doesn't want that because they have very customized notifications.

How can this be fixed? I know merchant notifications can be turned off in Authorize.net but we don't want that unless Hikashop is sending notifications instead.

As I said, when we switch to PayPal it works as desired but they are looking to switch away from PayPal

Is there any way that we can just update the plugin itself? or see the differences to patch it? I believe a developer who was working on it previously has customized the installation for other purposes so I wouldn't want to risk wiping those mods out given that I don't know the complete list of changes.

I went ahead and looked at the plugin code to compare the new version with the old version and the only difference I see is one line added which was setting a curl option to POST with a value of true in the onBeforeOrderCreate function, I don't see how that's going to do much for notifications? authorize the authorize.net plugin from 2.6.2 is identical to 2.6.3

They don't want order creation notifications, they want the confirmation e-mail which is handled by the change status e-mail... it's been working under PayPal perfectly for months.. When PayPal is used, HikaShop sends out the confirmation message.. They switched to Authorize.net and the notifications stopped... They no longer get the order confirmation, I verified in the e-mail logs that nothing was sent out as well.. but the moment we switch back to PayPal, it starts working again.

I have seen others in the forums post about similar issues with Authorize.net in the past

No, they do not want it to work like PayPal, they don't want the customer to leave the site. I only mention PayPal because the order confirmation e-mail that we designed works properly with that payment method.. We simply want our personally designed order confirmation e-mail to be triggered when the payment comes back as approved.. I did try SIM and that didn't give me a confirmation e-mail either, only the ugly authorized.net confirmation e-mail

By the way, we also have another client who uses 2.5.0 and I used my developer authorized.net credentials and the order confirmations come in perfectly as they should be.. but with 2.6.2 and 2.6.3 our custom order confirmation e-mails do not work.

Surely this is possible, I've looked at the code and you can see when the order is approved by the response code, so it seems like it should work.. and like I said, on our client site that is running 2.5.0 it DOES work.. so there's a problem somewhere

Ps. we extended our support/upgrade contract today out until 2017

The admin notifications should be irrelevant? .. I disabled it because they no longer wanted those.. they've been disabled for a long time so that shouldn't be the issue... the notifications were working long before that was disabled using another payment type.

I can provide you FTP and Admin if you want to take a look at it.. I set up a test site on another server even to try to eliminate a server problem as being the issue but that, as I suspected, wasn't the problem.. we do have another test site where it does work so I'm at a loss..

I see... so with authorize.net the way I have it they won't get the creation message if they are declined correct? if so then I can work with that. We had the create notification disabled because we didn't want them getting two messages.. I will work with this and test to make sure it functions as desired.
