You can now connect native Marketplace resources to custom environments. Previously, resource connections could only target production, preview, and development environments.

Choose custom environments when connecting a resource from the Vercel dashboard, Vercel CLI, or REST API. Vercel scopes the environment variables created by the connection to the selected environments.

For example, from the CLI:

vercel integration add neon --environment staging

Existing deployments do not change. Create a new deployment after connecting a resource or changing its environment scope.

Custom environments are available on Pro and Enterprise plans.

Read the docs for connecting from the dashboard, the CLI --environment flag, and the REST API envVarEnvironments field.
