Clickatell SMS Gateway TLS Changes

Clickatell have notified customers that they will be performing scheduled system maintenance on 14 August 2016. Following these changes they will no longer be supporting SSL 2.0 or SSL 3.0 but are adding support for TLS 1.2.

This only applies to HTTPS requests (not HTTP) made to the Clickatell API. We’ve completed some initial testing using their test TLS server and are happy to report all messages were delivered successfully. If you’re using fmSMS with Clickatell and HTTPS requests everything should continue to work after the 14 August 2016, but please let us know if you encounter any issues.
