# n8n

## Description

**n8n** is a workflow automation tool (similar to Zapier) — open-source, with both cloud and self-hosted options. In this system, it is used to **bridge the gap between Claude and external APIs**.

## Role in the Architecture

n8n specifically handles:

1. Receiving the webhook payload from [[entity-claude-ai|Claude]] — see [[concept-webhook-integration]]
2. Fetching the Instagram audio file from the Instagram CDN
3. Sending it to [[entity-groq]] for transcription
4. Returning the transcript to Claude or directly writing it into [[entity-notion]]

This is the implementation of [[concept-audio-transcription-workaround]].

## Cost

Roughly **$20–$30/mo** on cloud plans; self-hosting is cheaper but adds ops overhead.

## Setup

See [[action-setup-n8n-groq]] for the import + API key procedure. Prerequisite knowledge: [[prereq-api-webhook-basics]].
