I'm trying to set of a TriggeredSend definition. After a lot of playing around I got the system to load the ExactTargetWSDL.xml. Now I've got this error showing up, and i'm not sure why.
Create a TriggeredSend Definition Fatal error: Call to undefined method WSSESoap::addOAuth() in ET_Client.php on line 165
I'm guessing I'm missing some sort of dependency, but I'm not sure what it could be.
