Using Your API Key in API Calls

So, you’ve got your API key. How do you use it? It’s all about sending it in your API call as a header named X-N8N-API-KEY. Here’s an example to get you started:

Say you want to get all active workflows. Your curl request will look like this:

For a self-hosted n8n instance:

# For a self-hosted n8n instance
curl -X 'GET' \
'<N8N_HOST>:<N8N_PORT>/<N8N_PATH>/api/v<version-number>/workflows?active=true' \
-H 'accept: application/json' \
-H 'X-N8N-API-KEY: <your-api-key>'

For n8n Cloud:

# For n8n Cloud
curl -X 'GET' \
'<your-cloud-instance>/api/v<version-number>/workflows?active=true' \
-H 'accept: application/json' \
-H 'X-N8N-API-KEY: <your-api-key>'

See how simple that is? By including your API key in the header, you’re ensuring secure access to n8n’s powerful features. Now, let’s break down why this is so important.

The Importance of Secure API Authentication

Wondering why all this fuss about API authentication? It’s simple: security. In the world of automation and integration, your API keys are like the keys to your digital kingdom. They control who gets in and who stays out. By using n8n’s API keys, you’re not just accessing the REST API; you’re doing it safely and efficiently.

Think about it: without proper API authentication, anyone could potentially access your workflows, data, and integrations. That’s a nightmare scenario. But with n8n, you’ve got the tools to lock it down tight. And here’s the best part: it’s all user-friendly and straightforward.

Tips for Managing Your API Keys

Managing your API keys effectively is key to maintaining a secure and efficient workflow. Here are some tips to keep in mind:

• Regularly review and update your keys. Don’t let old keys linger; they could be a security risk.
• Use different keys for different applications. This adds an extra layer of security and helps you track usage.
• Keep your keys safe. Store them securely and never share them publicly.
• Monitor your API usage. Keep an eye on who’s accessing what and when.

By following these tips, you’ll ensure your API keys remain a powerful tool rather than a liability.

So, there you have it! You’re now armed with the knowledge to create, delete, and use API keys in n8n like a pro.
