Can I test our API handshake with CloudSMS prior to an SSL certificate renewal?

Yes you can. Prior to each new SSL certificate renewal on our production API end-points, the new SSL cert will be first provisioned onto the following test API end-points for you to verify your application:

General API end-point: https://www.commzgate.net:442

Reserved API end-point: https://vip.commzgate.net:89

If you are not able to reach these end-points, please contact us.
