Environment Variables

Required

Variable	Description
`VARD_API_KEY`	Your workspace API key. Found in Settings → API Key.

Optional

Variable	Description

Setting variables in different environments

Local development

.env.local


VARD_API_KEY=vard_live_xxxxxxxxxxxx

Vercel

Add environment variables in your project settings under Settings → Environment Variables. Make sure VARD_API_KEY is available for all environments (Production, Preview, Development).

Other hosts

Consult your hosting provider’s documentation for setting environment variables. The variable must be available at build time (not just runtime) if you’re using static export or ISR.

Security

VARD_API_KEY grants read access to your workspace’s published content. It is safe to include in server-side environment variables but should never be exposed to the browser.

Do not commit .env.local or any file containing your API key to version control.
