Hello,

I have received a notification from PayPal that they will be updating the IPN system, and I wasn't sure if this will have any impact on us. We're using 1.5.6 along with PayPal and PayPal Pro to process transactions. Below is PayPal's message.

Any input would be greatly appreciated!

--------------

Important PayPal dispute case tracking changes.

If you are currently using the Instant Payment Notification (IPN) process or the Case report in your current integration, we want to notify you of a change that may impact your business.

To ensure you don’t experience a disruption of PayPal service, we encourage you to make any applicable changes by July 7, 2015.

What is happening?

We’re enhancing our dispute management system to ensure you receive more detailed and timely information.

The first phase of this enhancement will encompass chargebacks and ACH bank returns. As part of this enhancement, we’ll be updating the format of the Case ID which is the unique identifier we assign to a dispute case.

Why is this happening?

Enhancing our dispute management system will provide more detailed, accurate, and timely information regarding disputes.

What do I need to do?

If you are directly integrating data from the IPN process and/or the Case report into your systems, you will need to ensure that your configuration will accept the format change for the unique dispute identifier as outlined here.

Data passed contains a case_id value. This value will now be formatted in two ways:

Existing format: PP-XXX-XXX-XXX-XXX
New format: PP-D-XXXX

For the new format, XXXX is an integer. The “D” indicates the case is a dispute.

Effective July 15, cases will be identified using either ID format until the transition to the new dispute management system is complete. This is expected to take several years.

As a best practice, merchants are encouraged to integrate flexibly so that any future changes to the unique case identifier can be made without integration changes.

When is this happening?

We will begin generating cases using the new format after July 15. To avoid any disruption to the way you process IPNs or the Case report, please update your integration by this date.

Thanks for your patience as we continue to improve our services.

Your Merchant Services Support Team

My bad, its a new update but question remains the same -

PayPal is upgrading the certificate to SHA-256. This endpoint is also used by merchants using the Instant Payment Notification (IPN) product.

One for Qphoria to answer, he's the Paypal expert here :-\

Update: I think this question is answered here:

https://www.paypal-knowledge.com/infoce ... cale=en_US

Basically, ask your webhost to make sure the server running your OpenCart site is SHA-256 compliant.

Qphoria, can you confirm that we understood it correctly?

I'm assuming that using the Standard PayPal Payment extension doesn't use IPN. Is this a correct assumption?

Wrong, PayPal Standard does use the IPN, the PayPal server calls back the OpenCart server with relevant payment messages, e.g. payment success etc. If I understand it correctly, the OpenCart server should use the secure protocol (SSL) and it needs to be SHA-256 compliant, the latter has to be confirmed by your webhost. Chances are that it already is.

What's Paypal? Is this some new fangled Buy-a-friend site? :joker:
As JN said, this is a server host/ssl compatibility thing.. As long as you didn't buy your server or your ssl certificate from the back of a van, you should have nothing to worry about. Use this site to check if your server is compatible:

Thanks Qphoria & JNeuhoff - I am glad you guys answered as I only have 10 days to get this upgraded before our site would stop taking payments.

And apologies for us non-coders being a pain in the neck...

Hi,

I don't have SSl set up on my opencart install.

But I'm using PayPal for payments and IPN is being used.

Will this IPN update affect my site?

Thank you! :joker:

It's the same for everyone. Whether you're using SSL or not, check with your hosting company. As long as the server software is up to date, you'll be all set.
