NiFi: How to get all ProcessorType via its REST API?

Question

Using this NiFi API end-point GET "/process-groups/{id}/processors", able to fetch all processors part of the root Process Group. Each Processor has a property called "type". So to fetch all unique Processor Type (Example: ConsumeKafka), I can iterate through all processors and look for its "type" property.

Is there any existing NiFi REST end-point to fetch all unique "Processor Types"? If not, please suggest an easier way to achieve this. Thank you!

The nifi-api endpoint you probably want is /flow/processor-types. There is a reference implementation in my NiFi Python client NiPyAPI
