Certificate Rotation for all Twilio REST API endpoints

Effective April 11, 2024, new certificates will be deployed for all our REST API endpoints (e.g., api.twilio.com), including all regional edge locations. Only the end-user certificate will be renewed, as well as the certificate serial number. The root and intermediate certificates will remain the same. Such updates are common practice and do not impact customers that are using Twilio's services unless you are pinning certificates or are managing them manually.

The certificate will be available on the testing domain ( https://tls-test.twilio.com ) on March 11, 2024.

We highly discourage customers from pinning certificates as it exposes them to potential security risks and can cause downtimes for their services. Twilio customers using pinned certificates have a high probability of failed API Requests. These customers are advised to add the new certificates by Apr 8, 2024. You can follow the information mentioned on the official documentation.
