Important Notice: Upcoming Change to Our API Security Certificate

30 Jun 2025

To maintain modern security standards, AWS (our cloud service provider) is updating how it signs digital certificates used for secure connections to our API.

What’s Happening?

Since August 2024, AWS has stopped cross-signing certificates with the older Starfield Class 2 (C2) certificate.
Full support for the old Starfield certificate will end on 31 December 2025.
Our API gateway will continue to use public certificates signed by AWS Certificate Manager.

What Do You Need to Do?

For API Consumers,

You may need to update your applications’ trust store and/or configuration before 31 December 2025 if:

Your applications’ trust store only uses the older Starfield Class 2 (C2) certificate.
You pin to the cross-signed certificate or the certificate hash of Starfield Services G2 rather than the public key of the certificate.
You configure dependency on the certifcate chain length. The chain length for ACM issued public certificates will reduce from 3 to 2 as part of this change.

Please update your applications/systems to trust Amazon Root CA and Starfield Services - G2 to ensure uninterrupted access before 31 December 2025. You may download the Amazon certificates via our documentation:

https://docs.developer.tech.gov.sg/docs/complete-apex-user-guide/sections/consuming/certificate-prerequisites

For API Publishers,

You may need to update your API’s configuration via APEX portal to reflect the certificate changes if you host your backend API in AWS and uses AWS Certificate manager for securing connections to the backend API before 31 December 2025. Steps to update your certificates here:

https://docs.developer.tech.gov.sg/docs/complete-apex-user-guide/sections/publishing/version-api https://docs.developer.tech.gov.sg/docs/complete-apex-user-guide/sections/publishing/publish-api?id=trusted-certificates
