Overview

This node acts as a global configuration store within n8n workflows, allowing users to set, get, delete, and manage configuration variables across workflows. It supports operations such as storing a single variable, retrieving a single variable, setting multiple variables at once, getting all stored variables, deleting a variable, and clearing all variables. This is useful for managing environment-specific settings, API keys, or any global data that needs to be shared and reused across multiple workflows.

Use Case Examples

1. Store an API key securely and retrieve it in different workflows without exposing it in logs.
2. Manage environment-specific configuration variables like project IDs or URLs that can be updated centrally.
3. Clear all stored configuration variables when resetting the environment.

Properties

Output

JSON

• _configStore
  • operation - The operation performed (e.g., getAll)
  • variables - An object containing all stored variables with their values or masked values if secure
  • count - The number of variables stored
    - The value of each variable if not secure

Dependencies

• Uses an internal in-memory Map to store variables globally within the n8n instance

Troubleshooting

• If a variable is not found during a get operation, the output will indicate 'Variable not found'. Ensure the variable name is correct and has been set previously.
• Secure variables are masked in logs and output to protect sensitive data; if you see '***SECURE***', it means the value is hidden for security reasons.
• Since the store is in-memory, all variables will be lost if the n8n instance restarts. Consider this when relying on persistent configuration.
