ServiceNow Executing a Flow Action via Script (Async and Sync)

Diff between asynch v synch

 

//-- Start Asynchronously: Uncomment to run in background. Code snippet will not have access to outputs.

                //-- sn_fd.FlowAPI.getRunner().action('global.glidepath__create_sso').inBackground().withInputs(inputs).run();

 

                //-- Execute Synchronously: Run in foreground. Code snippet has access to outputs.

                var result = sn_fd.FlowAPI.getRunner().action('global.glidepath__create_action').inForeground().withInputs(inputs).run();

                var outputs = result.getOutputs();

 

                //-- Get Outputs:

                //-- Note: outputs can only be retrieved when executing synchronously.

                var response_body = outputs['response_body']; // String

                var response_error = outputs['response_error']; // String

                var response_status_code = outputs['response_status_code']; // String

                var response_error_code = outputs['response_error_code']; // String

                var dag_run_id = outputs['dag_run_id']; // String

 

 

 

In this case it’s running a flow action – table name is sys_hub_action_type_definition

 

Value highlighted is internal name
