Hi All. I'm relatively new to NiFi and would like a little help in designing a data flow that looks like this: SELECT from a SQL data source split/convert to JSON optionally transform JSON merge to 500 record batches POST to target via REST API (requires session token from API auth POST) I know how to create this flow in NiFi. The part I'm having trouble with is including a step that gets a session token via the REST API auth endpoint. I can get the session token using InvokeHTTP no problem. I just don't know how to add the session token to the flow file(s) containing the data to POST to the API. Thanks for your help.
