Variable

Variables are key/value pairs that you can add to a specific Environment. Use these for storing configuration like API keys rather than hardcoding them into your Functions. Environment Variables are encrypted, so they are the preferred way to store API keys, passwords, and any other secrets that your Function needs to use.
