Full definition of environment variable
In automation: same workflow code, but the Slack channel ID is dev-channel in dev env and prod-channel in prod env. Best practice: never hardcode secrets or environment-specific values in workflow steps.

FAQ
Common questions about environment variable
Should env vars be secret?
Some yes (API keys, passwords) — keep those out of plain workflow fields. Some no (channel IDs, URLs) — visible to teammates who can view the workflow.
How do I rotate an env var?
In platforms that support them, update the value in one settings screen and every workflow picks it up on its next run, with no redeploy.
