# Environment variable schema

> Reference the Novu environment variable schema used in API requests and responses. Review fields, data types, and object structure for this resource.

### Environment Variable

Environment variable is a named value you define once in the dashboard and reuse across workflows. Each [Novu environment](/platform/developer/environments) can hold its own value for the same variable, so Development and Production (and any custom environments) stay isolated without duplicating workflow logic. Read more about environment variables on [environment variables documentation page](/platform/developer/environment-variables).
