@tdubz to help you out - would you mind answering some question for clarificcation - Did anything change recently — new GHL update, calendar reconnection, or workflow edits? Can you share the full error log from the Vapi call? "Success: false" alone doesn't tell me if it's a tool call failure, auth issue, or a GHL webhook problem. Is this a custom tool you built or the native GHL integration in Vapi? Which calendar type - Google, Outlook, or GHL's own?
