The NiFi API can be used to start and stop processors or process groups, and this might solve your use case. But NiFi does not have an API to run a processor only once, immediately, separate from its configured schedule. I have solved similar problems in the past by creating two separate upstream sources - one for scheduled operation, and one for ad-hoc operation. GenerateFlowFile, GetFile, or similar processors can be used to inject a flowfile where you need to kick off the flow.
