Environment Variables Documentation

OpenClaw manages environment variables through a hierarchical system that respects existing values without overriding them.

Loading Priority

The system follows a specific precedence order from highest to lowest priority:

Process environment - Variables already present in the parent shell/daemon
Local .env file - Located in the current working directory
Global .env file - Found at ~/.openclaw/.env
Configuration file settings - The env block in ~/.openclaw/openclaw.json
Shell environment import - Optional login-shell variables when enabled

Configuration Methods

You can define variables directly within the config file using two equivalent approaches:

{
  env: {
    OPENROUTER_API_KEY: "sk-or-...",
    vars: {
      GROQ_API_KEY: "gsk-...",
    },
  },
}

Shell environment import capability allows the system to run your login shell and import only missing expected keys.

Variable Substitution

Config files support variable references using ${VAR_NAME} syntax within string values, enabling dynamic configuration based on environment settings.

The documentation links to gateway configuration guides, FAQ materials about env var loading, and models overview pages for additional context.
