@Rothmny  Based on what you have shared, you should be able to accomplish this with  GenerateFlowFile and ExecuteStreamCommand processors. The GenerateFlowFile processor would be configured to generate a 0 byte FlowFile and scheduled using Cron so that it creates a FlowFile on your required schedule that will then trigger the execution of the ExecuteStreamCommand processor that will execute your python script. For calling rest-api endpoints via NiFi dataflows, you could use the InvokeHTTP processor.  Since the InvokeHTTP processor does not require and inbound connection, you could just have it as first processor in a dataflows scheduled with cron as well.  Or, if the invokeHTTP is called after your script successfully executes you could trigger with the FlowFile that exited the the ExecuteStreamCommandProcessor.
