Renders the prepared outbound call structure of a webhook as raw text, showing what payload would be sent to the endpoint.
HOOKVIEW — set as ReportType in def_report.
def Render(self, Param1="", Param2="", Param3="") -> str:
Param1 is the webhook code (optionally followed by ^ and additional parameters; only the first part is used). The report uses ObjHook to read the webhook definition, call prep_data(), and categorise the outbound payload. The result is wrapped in <xmp> tags for literal display. An error message is shown if HookLookupSql is invalid.
