Disable n8n Public API for Security
Ever wondered how a simple tweak can turn your n8n setup into a fortress? Let me tell you, it’s not just about setting up your workflows; it’s about locking down your system to keep the bad guys out. Today, we’re diving into a critical security step that you can’t afford to skip: disabling the public REST API in your n8n installation. And trust me, if you’re not using this API, you’re leaving a door wide open for anyone to stroll in and mess with your system. So, let’s get into how you can shut that door and secure your setup with just a few environment variable tweaks.
Why Disable the Public REST API?
First off, let’s talk about why this matters. The public REST API in n8n is a powerful tool, no doubt. It lets you perform the same tasks you can do in the GUI, but programmatically. Sounds great, right? But here’s the kicker: if you’re not using it, it’s a security risk. Why? Because it’s an entry point for potential attackers. If you’re not using this API, n8n recommends disabling it to improve your installation’s security. It’s like leaving your front door unlocked when you’re not home. You wouldn’t do that, so why leave your API open?
How to Disable the Public REST API
Alright, let’s get to the nitty-gritty. Disabling the public REST API is straightforward. You just need to set the N8N_PUBLIC_API_DISABLED environment variable to true. That’s it. Here’s how you do it:
- Open your environment variable settings.
- Locate the N8N_PUBLIC_API_DISABLED variable.
- Set it to true.
Boom! You’ve just secured your n8n installation by closing off an unnecessary entry point. Now, let’s take it a step further.
Disabling the API Playground
While we’re at it, let’s talk about the API playground. It’s a great tool for testing and exploring your API, but again, if you’re not using it, it’s another potential vulnerability. To disable the API playground, you’ll set the N8N_PUBLIC_API_SWAGGERUI_DISABLED environment variable to true. Here’s how:
- Open your environment variable settings again.
- Find the N8N_PUBLIC_API_SWAGGERUI_DISABLED variable.
- Set it to true.
By doing this, you’re further tightening your security by removing another potential attack vector. It’s all about minimizing your exposure, right?

The Bottom Line
So, there you have it. Disabling the public REST API and the API playground in your n8n installation is a simple yet powerful way to enhance your security. It’s about taking control of your system and not leaving anything to chance. Remember, if you’re not using these features, there’s no reason to leave them enabled. Take a few minutes to set those environment variables, and you’ll sleep better at night knowing your n8n setup is locked down tight.
