Netlify Environment Variable Scope for Build Functions

Netlify Function Environment Variable Scope

The configuration allows setting environment variables for deployments.

Uncertainty exists regarding which specific build phases—pre-build, build execution, or post-deploy hooks—reliably inherit all defined site-level environment variables when executing a Netlify Function.

Verification Questions

• Does the function runtime environment guarantee access to all variables defined in the site settings?
• Are there documented constraints on which specific function types support full environment variable inheritance?
