How to use the RestLookupService to make REST API calls?

Explorer

I am trying to learn how to use the RestLookupService to make REST API calls. But since it is a controller service, not a processor.. so I need some guidance on which processor I should use.. where I can configure this service. I want to save the response that this service returns to somewhere else..let's say to the local file system...using PutFile.

You need to configure your RestLookupService with the details of the external REST service that you want to use for lookups and then use the LookupRecord processor in your flow to perform the actual lookups.

The LookupRecord processor takes a reference to the RestLookupService controller service.

If you are simply looking to GET from a REST API endpoint and take the response and write to a local file on the server where your NiFi service is running, you'll want to use the InvokeHTTP processor and feed that to your putFile processor.
