Implementation Reference
- The handler function that executes the activate_workflow tool. It validates parameters, authenticates, and sends a PATCH request to the ServiceNow wf_workflow table to set active=true.def activate_workflow( auth_manager: AuthManager, server_config: ServerConfig, params: Dict[str, Any], ) -> Dict[str, Any]: """ Activate a workflow in ServiceNow. Args: auth_manager: Authentication manager server_config: Server configuration params: Parameters for activating a workflow Returns: Dict[str, Any]: Activated workflow details """ # Unwrap parameters if needed params = _unwrap_params(params, ActivateWorkflowParams) # Get the correct auth_manager and server_config try: auth_manager, server_config = _get_auth_and_config(auth_manager, server_config) except ValueError as e: logger.error(f"Error getting auth and config: {e}") return {"error": str(e)} workflow_id = params.get("workflow_id") if not workflow_id: return {"error": "Workflow ID is required"} # Prepare data for the API request data = { "active": "true", } # Make the API request try: headers = auth_manager.get_headers() url = f"{server_config.instance_url}/api/now/table/wf_workflow/{workflow_id}" response = requests.patch(url, headers=headers, json=data) response.raise_for_status() result = response.json() return { "workflow": result.get("result", {}), "message": "Workflow activated successfully", } except requests.RequestException as e: logger.error(f"Error activating workflow: {e}") return {"error": str(e)} except Exception as e: logger.error(f"Unexpected error activating workflow: {e}") return {"error": str(e)}
