Certificate Rotation for all Twilio REST API endpoints

Effective April 15, 2024, new certificates have been deployed for all our REST API endpoints (e.g., api.twilio.com), including all regional edge locations. Only the end-user certificate has been renewed, as well as the certificate serial number. The root and intermediate certificates have remained 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.

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.
