Hi all,   I am a really beginer in Apache NiFi and I am trying to find the best way to do the following process.   I have an API that exposes an endpoint that provides me a token for next requests (available for few hours). I would like to store this token for general purpose, because I need other flows accessing to this token.   I would preffer not using Files or external Databases, so  I was wondering about using variables... but honestly... no idea if this is the best way.   So far, I know how to connect with the API, (InvokeHTTP), and getting the token (EvaluateJsonPath), but I don't know how to store and where (Variable?) and how to use it in another flow.   Current flow so far: Store Token: GenerateFlowFile -> InvokeHTTP ->EvaluateJsonPath -> ?? New request using token: GenerateFlowFile -> InvokeHTTP (Here I need to access the token)   Can anyone help me?   Thank u so much!!   Javier ... View more
