TLS Updates {#tls-1-3}
======================

We are making changes to our implementation of Transport Layet Security (TLS).

TLS 1.3
-------

To maintain the highest security standards for both browser-based and server-to-server connections, we will enable TLS 1.3 on the endpoints listed below. This enhancement is optional and will supplement the existing TLS 1.2 support, which will remain in place with no plans for removal.  
The changes will be implemented on the following dates and endpoint URLs:  
**Testing environment**: May 26, 2026  
*ics2wstesta.ic3.com*  
*ics2wstest.ic3.com*  
*apitest.cybersource.com*  
**Production environment**: June 2, 2026  
*ics2wsa.ic3.com*  
*ics2ws.ic3.com*  
*api.cybersource.com*  
*api.in.cybersource.com*  
*ics2ws.in.ic3.com*  
Please contact your Customer Support representatives for any questions you may have about this change.

TLS Certificate Lifetime Reduction
----------------------------------

In alignment with new CA/Browser Forum regulations, the maximum TLS certificate lifetime will be reduced gradually as follows:  
• From today until March 15, 2026, the maximum lifetime for a TLS certificate is 398 days.  
• March 15, 2026, the maximum lifetime for a TLS certificate will be 200 days.  
• March 15, 2027, the maximum lifetime for a TLS certificate will be 100 days.  
• March 15, 2029, the maximum lifetime for a TLS certificate will be 47 days.  
For more information about the TLS certificate lifetime changes, please visit the following link:

**How will this change affect connectivity?**  
Server level (leaf) SSL/TLS certificates issued by Cybersource will remain valid until their scheduled expiration. Server level (leaf) TLS certificates have shorter lifespans and must be reissued more frequently. Cybersource therefore recommends that clients trust the root certificate instead.  
**What is our recommendation?**  
We continue to recommend trusting the Root TLS certificates for all secure endpoints. This approach removes the need for periodic renewal of server level certificates and helps prevent connection failures caused by expired leaf certificates.  
**How can I tell what TLS certificate I am using?**  
Contact your server administrator or your network support team.  
**Where can I find the TLS Root certificate?**  
Be sure that you continue to trust the root certificate to maintain connectivity with supported endpoints. You can download the root certificate here:
