# Env. variables

> DEV, UAT, and PROD environment variables for builds and integrations.

**Env. variables** store secrets and config per **environment** (DEV, UAT, PROD). **Agent Builds** and integrations read these at runtime — values are not stored on the **Agent Graph** canvas.

<Note>
  Sensitive values display masked in the table. Tools and channels reference env keys by name — keep naming consistent across DEV → PROD promotion. Permission: `workspace.sidebar.environment`.
</Note>

## Configure variables

1. Open **Env. variables** from the workspace sidebar.
2. Click **New Environment** or edit an existing variable row.
3. Enter **Variable Name** and values for **DEV**, **UAT**, and **PROD** as needed.
4. Save each row.
5. When deploying, assign the **Agent Build** to the environment whose values you configured ([Builds & environments](/builds/environments)).

<Tip>
  Keep variable **names** consistent across DEV → PROD. Only the **values** should change (API keys, base URLs, feature flags).
