n8n-nodes-config-loader

Config Loader is an n8n community node that lets you load arbitrary configuration or credential data from a single JSON blob (stored in credentials) and inject it directly into your workflow’s data. This makes it easy to centralize environment-specific settings, API endpoints, tokens, or other variables without hard-coding them into each node.

n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation to install this node in your n8n instance.

What It Does

• Reads a JSON object from the Config Loader Auth credential.
• Safely parses the JSON.
• Merges all properties from the JSON into the current item’s json at the root level.

This allows you to keep all of your configuration (URLs, keys, IDs, feature flags, etc.) in one place, then use built-in n8n filters or expressions elsewhere in your workflow to pick out exactly what you need.

Credentials: Config Loader Auth

Before using the node, you must create the Config Loader Auth credential:

• In n8n, go to Credentials → New Credential → Config Loader Auth.

• In the Configuration JSON field, paste a valid JSON object. For example:

  {
    "serviceA": {
      "host": "https://api.servicea.com",
      "apiKey": "YOUR_API_KEY"
    },
    "serviceB": [
      {
        "id": "dev",
        "endpoint": "dev.example.com",
        "token": "DEV_TOKEN"
      },
      {
        "id": "prod",
        "endpoint": "api.example.com",
        "token": "PROD_TOKEN"
      }
    ],
    "featureFlagX": true,
    "timeout": 30
  }
  

Usage

• Drag the Config Loader node into your workflow.

• Select the Config Loader Auth credential you configured.

• Connect it to the rest of your workflow.

• Run the workflow. All keys and values from your JSON will be available at the root of each item under {{$json}}.

• Filter or extract the specific values you need using n8n’s existing Split Out, Filter, IF, or Function nodes.

Examples

• 🔑 Inject API Credentials Store all your API endpoints, keys, and secrets in one JSON blob. Use Config Loader at the start of your workflow to inject, then pass specific values into HTTP Request nodes.

• 🛠️ Feature Flags Toggle features on or off by storing boolean flags in the JSON. Combine with an IF node to control branching logic without editing each node.

Compatibility

Tested with n8n v1.91.3 and above. Should work with any later versions, but please report issues if you encounter problems on significantly newer releases.
