Environment Variables

Environment Variables are persistent variables that are available across your entire workspace. Typically, these are used to store things like external API keys or other sensitive information that you need to use across multiple function stacks, without storing it in a database table.

Environment variables can only be updated from your workspace settings.

They'll be available in the dropdown under ENV
