I am not sure you have provide enough detail on what it is you are trying to accomplish. 

Are you trying to setup your NiFi securely and use oath 2 based provider to authenticate your users in to NiFi? If so, you may find this helpful:

If you are trying to interface with an oath2 compliant endpoint via a NiFi dataflow, this may be helpful:

The OAuth2TokenProviderImpl controller service was added to NiFi around the 1.13 release timeframe.
At the time of its creation, there were no processors within NiFi yet that use it natively.

It's only usable in scripted processors that customers would use. However the Apache NiFi community is  working on ways to leverage this controller service in processors such as InvokeHTTP in the future.

You are encourage to participate and contribute to the Apache NiFi product.

Hope this helps,

Matt

We have started using 1.13 version. Any example or documentation using the OAuth2TokenProviderImpl controller service is much appreciated.
