Welcome back to our n8n automation series! If you are integrating external APIs using the HTTP Request node, you must authenticate your calls to avoid 401 Unauthorized errors. In this fully updated 2026 tutorial, we show you exactly how to add Basic Auth, Bearer Tokens, Header Auth, and OAuth2 directly into your n8n workflows!

We will walk you through the n8n Credentials Manager, demonstrating how to securely store your API keys instead of hardcoding them in plain text. You will also learn how to dynamically pass tokens via HTTP headers and handle complex OAuth2 flows with third-party services. Mastering API authentication is the key to connecting your workspace to the rest of the web!
