CardinalCommerce will be updating a certificate that is set to expire on March 24, 2026. The leaf certificate will be updated on March 10, 2026.
The certificate that is expiring is the wildcard server certificate used on most of Cardinal’s externally facing sites.
The expiring certificate details:
Common Name (CN): *.cardinalcommerce.com Serial Number: 0e:fe:06:35:d2:9c:9f:d5:6d:eb:af:2c:63:6d:84:b9 Date of Expiry: 03/24/2026
The new leaf certificate is: Common Name (CN): *.cardinalcommerce.com Serial Number: 05:6a:e3:77:86:ef:f2:bf:09:b3:13:22:f2:0d:ef:6c Date of Expiry: 02/21/2027 *Please request chain from our support team if needed
Intermediate Certificate Details (remain the same): Common Name (CN): DigiCert Global G2 TLS RSA SHA256 2020 CA1 Serial Number: 0c:f5:bd:06:2b:56:02:f4:7a:b8:50:2c:23:cc:f0:66
Root Certificate Details (remain the same): Common Name (CN): DigiCert Global Root G2 Serial Number: 03:3a:f1:e6:a7:11:a9:a0:bb:28:64:b1:1d:09:fa:e5
Customer Responsibilities:
If you trust on the leaf certificate, you need to ensure the new server certificate is loaded in your trust store prior to March 10, 2026.
It is imperative that we perform the testing and or migration before certificate expiration on March 24, 2026, otherwise services may be impacted.
When do these changes take place?
The new certificate will be updated in our production environment on Tuesday, March 10, 2026 at 10:00 AM EST.
Testing – How can I test these changes?
Customers are encouraged to work with their network teams to ensure they can support the updated certificates.
No new parameters or fields are required for these changes. If you do not trust the new certificate, you will be unable to connect to Cardinal endpoints receiving a connection timeout or certificate error response.
