Send text messages through a SMS gateway via HTTP over Internet

I’m using the Asterisk 11.24.1 and FreePBX applications, and am looking for a possibility to send within a given context short text messages through a SMS gateway accessible via HTTP/S over the Internet. I’m looking for an application that can be used in conjunction with Clickatell and/or Free Mobile.

Searching around, I only seem to find the ZIM-SMS application which seems to correspond to my needs, however the link to the source code seems to be broken, and cannot find it elsewhere :frowning:
