LiveWhale SupportHandlers are what drive custom module development in LiveWhale. In a sense, every handler is a window of opportunity in the CMS’s operation into which you can insert custom code. Any custom module will use one or more handlers.
For a primer, check out the user guide Introduction to Custom Module Development.
