P12 Cert Update SOAP API Update for May 13th 2025

mrana998 — Mon, 06 Jan 2025 19:23:26 GMT

Hello,

I was wondering when this new change gets implemented on May 13th: https://developer.cybersource.com/docs/cybs/en-us/platform/relnote/all/na/rn-2025-01-03/rn-announce.html

Will older version get affected and need to add a p12 cert. or will it only be version 1.219?

Thank you.

From what I’ve read in the release notes: https://developer.cybersource.com/docs/cybs/visit /en-us/platform/relnote/all/na/rn-2025-01-03/rn-announce.html
The change seems to apply specifically to version 1.219 and above. Older versions shouldn’t require the p12 certificate unless you update to a newer version. It’s worth keeping an eye on future updates to make sure there aren’t any unexpected changes to older versions.

The update mentioned for May 13th, 2025, will primarily affect version 1.219 and newer, according to the release notes. Older versions of the API should not be directly impacted, but it's important to stay updated with any changes outlined in the official documentation. If you're using a version older than 1.219, you might want to check if the update requires upgrading to that version to avoid compatibility issues. Regarding the P12 certificate, it looks like the requirement will apply to the newer version (1.219) and not older ones, but it's always a good idea to verify with Cybersource support to confirm any specifics for your setup.

Could someone who only uses the SOAP Toolkit API explain what changes are necessary? We build an XML document in our ERP and then send that in a POST request to the CyberSource endpoint. All the documentation about this P12 certificate talk about using their Java, PHP or C+ toolkits. We don't use any of that for transactions.

We do use their Node toolkit to pull down two reports.

No help at all. Not even from CyberSource.

I got zero help from CyberSource. In fact, they switch to a new token format without telling us. We were told that this switch would take place on our timeline, but then they switched the format on us without notice. Also, the P12 Certificate didn't pertain to us, since we don't use a toolkit. We make endpoint calls. I explained that to CyberSource for months before they came back to tell us we were correct.

Bottom line, CyberSource offers zero support.

Hi,

The P12 certificate update taking effect on May 13, 2025 applies specifically to SOAP Toolkit API version 1.219 and higher. Older versions should not be impacted, but it’s always best to verify with CyberSource support if you're using a custom or deprecated setup.

If you plan to upgrade to 1.219+, then yes — you'll need to implement the P12 cert as outlined in their documentation.

Hope this helps.

Hey,

Yeah I was also looking into this Cybersource P12 cert + SOAP API update thing, and honestly it feels a bit confusing at first glance.

I faced something similar when a payment API we were using suddenly pushed cert-based auth changes, and older endpoints didn’t break immediately but started acting weird after a short window.

From what I understood (not 100% sure though), usually these updates don’t break everything at once — older versions sometimes keep working but get “soft deprecated”, and then you’re forced to move to the newer auth method.

What worked for me:

I checked which API version was actually still supported in production logs

Started testing P12 cert in sandbox early (don’t wait till deadline tbh)

Kept both old + new flow running in parallel for safe migration

We also had a small internal dashboard in Dooflix to track API failures, and that helped catch issues early before users noticed.

Not sure if it’s exactly same case here, but I’d definitely not rely on old SOAP version after the date.

Are you planning to migrate fully before May 13th or just test first and wait?Hey,
