Yep!  Had moved on to that after your response and written up a JIRA for my team to build the needed tool.  Thanks again for the response.  My plan is the below   > Find all the processors which may have state, then check if each has state, and if so, clear it.   Find processors of used types which can contain state: e.g., QueryDatabaseTableRecord For each, pull the state by the ID and check if it has any stored state if totalEntryCount of cluster or local state is non-zero If so, call the clear state endpoint Query URL: /nifi-api/flow/search-results?q=QueryDatabaseTableRecord Pull Processor State: /nifi-api/processors/41584e33-adc6-171d-0000-0000581caccb/state Clear Processor State: POST /nifi-api/processors/41584e33-adc6-171d-0000-0000581caccb/state/clear-requests   ...

Sure.  I had to make some extract it from a larger PG and make some adjustments due to key code being in a parameter.  But the remainder of the parameters are really placeholders for your environment information.  The main complication might be that I used a few external controller services that you will have to replace.  But their names in the externalControllerServices JSON should help you replace them.   ...

@Sivaluxan NiFi exposes APIs for a lot of endpoints.  So not really sure what you are trying to accomplish in your use case.  If you want to use a third party app to access info exposed by NiF that is possible.  Or are you trying to setup some custom endpoint to expose some custom data? Here you can find NiFi Rest-Api documentation for the latest NiFi release: https://nifi.apache.org/docs/nifi-docs/rest-api/index.html You can also find the NIFi rest-api documentation for your installed release directly in the application via the global menu ( 3 horizontal lines upper right corner of UI) --> help.   If you found that the provided solution(s) assisted you with your query, please take a moment to login and click Accept as Solution below each response that helped.
