Authorize.Net Technical Updates

[Danielle]

We received the following e-mail from authorize.net. We are using the built-in AIM module. Does this affect our store at all? Will the module need to be updated, or will it work fine as is?

Dear Authorize.Net Merchant:

Over the next few months, we are making several updates to our systems that you need to be aware of. They are all technical in nature and may require the assistance of your web developer or shopping cart/payment solution provider.

Please read this email carefully, and if you need to find a web developer to help you, please check out our Certified Developer Directory at www.authorize.net/cdd.

Akamai SureRoute Reminder
As we get further into 2016, we want to remind you of our previously announced Akamai SureRoute implementation plan and timelines. Using Akamai's technology will help safeguard against interruptions caused by issues beyond our direct control, such as Internet congestion, fiber cable cuts and other similar issues.

If you have not already, please review the announcement and the Akamai FAQs to determine what action you should take for your particular solution. If your solution uses a firewall, please pay particular attention to this section of the FAQs to make sure you avoid any disruptions to your transaction processing.

Transaction and Batch ID Reminder
In the coming months, due to system updates, it will be possible to receive Authorize.Net IDs (Transaction ID, Batch ID, etc.) that are not in sequential order.

For example, currently, if you receive a Transaction ID of "1000," you could expect that the next Transaction ID would not be less than 1000. However, after the updates, it will be possible to receive a Transaction ID less than the one previously received.

If your system has any functionality that expects Authorize.Net-generated IDs to be sequential, please update it immediately so that you will not see any disruptions.

Additionally, please make sure that your solution does not restrict any Authorize.Net ID field to 10 characters. If you are required to define a character limit when storing any of our IDs, the limit should be no less than 20 characters.

RC4 Cipher Disablement
In an effort to ensure that all of your server-to-server communications with the Authorize.Net platform (both transactional and otherwise) maintain the highest levels of security, we will be disabling the RC4 cipher suite during the first half of 2016. A follow-up notification will be sent out once specific dates for the disablement are ready for the sandbox and production environments.

For now, if you have a solution that relies on RC4 to communicate with our servers, please update it to a current, high-security cipher as soon as possible. Please review our API best practices blog post for more information.

TLS Remediation for PCI DSS Compliance
As you may already be aware, new PCI DSS requirements state that all payment systems must disable TLS 1.0 by 2018. Though we are still finalizing our plans for remediating TLS 1.0 in both sandbox and production, we will be disabling TLS 1.0 in sandbox and production in early 2017. This is to ensure that we are compliant ahead of the PCI date.

In addition, we are discussing the possibility of disabling TLS 1.1 at the same time, because while it is not expressly forbidden, there are enough concerns surrounding it. TLS 1.2 is currently the strongest available protocol, and we strongly urge all merchants and developer partners to use it for their API integrations.

For more information, including updates to the dates we anticipate disabling TLS in each environment, please refer to our previous blog post.

Sincerely,
Authorize.Net

Danielle, navigate to https://www.ssllabs.com/ssltest/ and enter your store's web-address to see what the current "state" of your SSL certificate is. Your SSL-cert should support the TLS 1.2 protocol (or, for now, at least TLS 1.1); if it doesn't, you'll need to contact your web-host to rectify the situation.

The Zen Cart module for v154 and newer will work fine as is. But, as lat9 mentioned, it's up to you and your hosting company to ensure that your server is capable of working with the changes Authorize.net are making.

[Danielle]

Perfect, thank you both. That test was fine, I just wanted to make sure there was nothing else that needed to be done.

Our SSL tests fine, but does the above information mean that the built-in authorize.net module for v139 may not work?

Yes. It probably will not work.
But I'm pretty sure that the one in v155 will work fine on your 139 site, as long as you replace the language file along with the module file.

[AvaAdorn]

I have a 139 site. What language file and module file exactly gets replaced and with what? I have the authorize.net AIM module.

[lat9]

You'll need to copy the following files and directories from the Zen Cart 1.5.5a distribution to like-named files/directories for your Zen Cart 1.3.9h store:

1. /includes/languages/english/modules/payment/authorizenet_aim.php
2. /includes/modules/payment/authorizenet_aim.php
3. /includes/modules/payment/authorizenet/*.*
