Data transfer via nifi api

Question

Hello,

how do I properly use the nifi-api to create flowfile from a file? I tried to do what is described here: https://nifi.apache.org/docs/nifi-docs/rest-api/index.html under 'Data transfer'

I've tried to use a simple curl command to transfer a file as flowfile to an input port as follows:

curl -X POST -F 'file=@Documents/Nifi_Docs/example.txt' http://10.0.1.111:8080/nifi-api/data-transfer/input-ports/dac743ae-0189-1000-c6a6-efd211a162d1/transactions/1010/flow-files

As response I get a 415 error Unsupported Media Type. What is the supported media type then? Anyone tried this before? What is the transaction id good for? I just put 1010 as a random number.

I also tried sending from postman

NiFi's remote input ports are designed to receive NiFi FlowFiles transmitted to the remote-input port by a NiFi Remote Process Group (RPG) using NiFi's Site-to-Site (S2S) protocol. They are not intended to be used for pushing arbitrary files into a NiFi dataflow.

For moving files in to NiFi, you should be using a NiFi processor for that. There a variety of different of different processors available to include but not limited to ListFile+FetchFile, ListSMB+fetchSMB, listSFTP+FetchSFTP, GetFile, HandleHTTPRequest+HandleHTTPResponse, ListenHTTP, etc.
