How to handle audio file received via Webhook in n8n?

Questions
1

Hi everyone,

I’m working on a study project and I’m facing an issue using the n8n Webhook node.

My web application sends 3 text fields and an audio file to a Webhook in n8n. The text fields arrive correctly and I can access them. However, the audio file arrives as binary, and I’m not able to interact with it in the workflow.

This audio file is essential because I want to use it in the next step, where an AI agent will process or transcribe the content.

:backhand_index_pointing_right: How can I handle the audio file received in binary format inside n8n, so I can use it later (e.g., save it, convert it, or send it to an API)?

I really appreciate any help or guidance you can provide. :folded_hands:

Hi @kaioba

You can pass the audio through a transcriber using openai. Then merge the results togther.
