Release Notes {#rn-general} =========================== These release notes cover all releases to the production server for the week ending March 6, 2026. Announcements {#rn-announce} ============================ These announcements are for March 6, 2026. Webhooks Updates {#webhooks-validations-decommission} ===================================================== Webhooks version 1 will be decommissioned in April 2026. See [Webhooks version 2 in the Developer Center](https://developer.cybersource.com/api-reference-assets/index.md#webhooks ""). TLS Updates {#tls-1-3} ====================== We are making changes to our implementation of Transport Layer 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. We will make changes to these endpoints on these dates: **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* Contact Customer Support if you have any questions about these changes. 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. Review the information in this blog for more information about the TLS certificate lifetime changes: [tls-certificate-lifetimes-will-officially-reduce-to-47-days](https://www.digicert.com/blog/tls-certificate-lifetimes-will-officially-reduce-to-47-days "") **How will this change impact 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?** Continue trusting the root certificate to maintain connectivity with supported endpoints. You can download the root certificate from this article: [?code=KA-09802](https://support.visaacceptance.com/knowledgebase/Knowledgearticle/?code=KA-09802 "") Contact your Customer Support representatives for any questions you may have about this change. Features Introduced This Week {#rn-features} ============================================ **AFT and OCT Transactions** \| RM-42567 ---------------------------------------- Description : This release enhances the payment authorization API for Account Funding Transactions (AFTs) and Original Credit Transaction (OCTs). The response message contains the source of the funding in the payments.card.vpc-edqp-afs-enhancement field. Mandate : Does not apply. Audience : Merchants who accept AFT and OCT payments. Benefit : The funding source is needed to support Visa Flexible Credential. This would help to apply credit card surcharges. Technical Details : None. Important Dates : Released to production March 4, 2026. Fixed Issues {#rn-fixed-issues} =============================== **Vantiv Transactions** \| RM-41337 ----------------------------------- Description : Transactions processed through Vantiv will now time out after 30 seconds. Audience : Merchants who process transactions through Vantiv. Technical Details : None. Important Dates : March 4, 2026. Known Issues {#rn-known-issues} =============================== **Transaction Search** \| EPS-36336 ----------------------------------- Description : Applications that are showing as Challenge or Not Run in Transaction Search will instead show as Failed in Similar Search. Audience : Users of Similar Search in the Business Center. Technical Details : None. Workaround : No. **Visa Platform Connect Transactions** \| EPS-36391 --------------------------------------------------- Description : All transactions using 3-digits exponent currency must be performed with the last digit as a zero. If a transaction is sent with different last digit (`1-9`), we will adjust the value to `0`. Audience : Merchants using 3-digits exponent currencies through Visa Platform Connect. Technical Details : A discrepancy was found specifically for credit authorization transactions, where an initial authorization and settlement transaction performed without a 0 does not benefits from the same logic, leading to rejections from Visanet. Workaround : Until further notice, consider performing an authorization and settlement transaction with the last digit set to zero, in case there is a possibly of future credits on your orders. If you are affected by this issue, consider performing a standalone credit.
