# Basic Understanding of APIs and Webhooks

## Prerequisite

Basic technical literacy regarding:

- **API keys** — what they are, how to generate them, where to paste them safely
- **Webhook URLs** — production vs. test URLs, how HTTP POST works
- Tool navigation in [[entity-n8n|n8n]] (node configuration, credentials)
- Tool navigation in the [[entity-groq|Groq]] console

## Why It's Required

While the speaker provides templates, setting up the system requires:

1. Navigating n8n and configuring the imported workflow
2. Generating an API key in Groq and pasting it into the correct node
3. Copying the production webhook URL from n8n into [[entity-notion]]

A basic understanding of how data passes between applications via HTTP POST is necessary to **troubleshoot** if the transcription pipeline fails — for example, a 401 error indicates a bad API key; no webhook response means the URL is wrong or n8n is offline.

## Reason

The system relies on chaining multiple third-party tools together. If a webhook URL is incorrect or an API key is invalid, **the pipeline breaks silently** and the user must trace the failure across at least three services.

## Setup Step

The specific procedure: [[action-setup-n8n-groq]]. Conceptual background: [[concept-webhook-integration]].
