curl \ -X POST \ -H "Content-Type: application/json" \ -H "X-Thunder-Secret-Key: secretkey" \ --data-ascii "\"Hello World!\"" \ http://thunder.example.com/api/1.0.0/[API key]/channels/[channel]/
All requests to the HTTP API must provide X-Thunder-Secret-Key header that should contain the private API key.

Getting high CPU usage?
Before giving up on thunderpush, check it's logs and look for errors like this one error: [Errno 24] Too many open files. If you're seeing them, it means that you've reached the limit of open file descriptors on your system. The only thing you need to do is to raise the limit. Following SO answer will tell you how to do it: http://stackoverflow.com/a/4578356/250162 Then simply restart thunderpush, forget about the problem and get a cold one!
