n8n API Authentication Explained: Keys, OAuth & Basics
Learn how to connect external apps in n8n using API authentication, including API keys, OAuth2, and basic authentication. This tutorial breaks down how APIs work and how to securely connect tools like Gemini, Gmail, and more.

In this video, you’ll learn how to take your n8n workflows to the next level by integrating external applications using APIs. We walk through the credential system inside n8n and explain the three most common authentication methods: basic authentication (username/password), API keys, and OAuth2. You’ll understand when to use each method and why security matters when connecting your workflows to external systems.

We also explore real examples, including connecting to tools like Gemini and Google services, and explain concepts like bearer tokens, client IDs, and access tokens in a simple, beginner-friendly way. By the end, you’ll know exactly how APIs enable communication between apps—and how to implement them in your own automations.
