CommzGate API SSL Cert Update for end-point

Thursday, 13 June 5 minutes

The maintenance is now complete. Thanks for your patience.


The scheduled maintenance is now underway. We'll keep you updated on our progress.


Please be informed that we will be updating the SSL certificate for our general API end-point at You are not affected if you are using our reserved end-point at

Impact: If you are using our API end-point at, you can pre-test the SSL handshake with the new cert prior to the actual cert update using our sandbox URL and port as follows:

For the sandbox URL above, real response codes will be returned if your SSL handshake is successful but no actual SMS messages will be delivered.

The new client and intermediate SSL certs can be downloaded from here:

Please import the new certs into your SSL keystore if necessary. Do contact us at if you require special assistance.
