Urgent Action Required for Optus SMS Suite: SSL Certificate Update

On Friday, 27 February 2026, at 12:00 (midday) AEDT, a new SSL certificate will be installed for:
• sms.optus.com.au
• api.sms.optus.com.au

New Certificate Details:
The new certificate details are available now at:
https://sms.optus.com.au/docs/en/integrations/api-documentation/ssl-certificates/

Action Required:
If your application performs certificate pinning or stores SSL certificates in a custom trust store, you will need to update your configuration with the new certificate details.

Important: failure to update stored certificate information may result in the inability to send messages across API Services including two-factor authentication and Campaign Manager API services once this time passes.
