```auto
curl -X 'POST' \
'http://localhost:9000/asr?task=transcribe&output=json' \
-H 'accept: application/json' \
-H 'Content-Type: multipart/form-data' \
-F 'audio_file=@signal-2022-12-11-160613.ogg;type=video/ogg'
```
How can I turn this into a node red flow using the http request node? The file can come from a file node.
Just putting the binary buffer in payload does not solve the issue and in the response message it says that field audio\_file is missing.
So I guess I somehow have to tell the http request node that this binary buffer from the file node is "audio\_file"
My Use Case: I'm trying to get a transcription for an audio file via a whisper web service: [GitHub - ahmetoner/whisper-asr-webservice: OpenAI Whisper ASR Webservice API](https://github.com/ahmetoner/whisper-asr-webservice/)

Have you searched the forum? It has been covered many times.
This answer is a good example...

File Upload To perform a file upload, msg.headers["content-type"] should be set to multipart/form-data and the msg.payload passed to the node must be an object with the following structure: { "KEY": { "value": FILE\_CONTENTS, "options": { "filename": "FILENAME" } } } The values of KEY , FILE\_CONTENTS and FILENAME should be set to the appropriate values.

Hi,
thank you, I found other topics but the solution didn't work (they were splitting the message in multipart headers manually). Your solution from the pdf file works.
