# List project environment variables

> List environment variables visible to a Vercel integration.

`listVercelProjectEnvironmentVariables` lists variables for one project.

```ts automations/list-vercel-env.automation.ts theme={null}
import { automation } from "automate.ax"
import { listVercelProjectEnvironmentVariables } from "automate.ax/vercel"

export default automation("List Vercel environment variables", () => {
  const variables = listVercelProjectEnvironmentVariables({
    project: "docs-site",
  })
  variables
})
```

`project` is the project ID or name. Optional `gitBranch` filters preview variables and `customEnvironmentId` filters a custom environment. `teamId` overrides the OAuth installation team. OAuth integrations normally see only variables owned by that integration unless granted global project-environment-variable access. The output preserves Vercel's typed response shape.
