# List Browserbase function versions

> List immutable versions of one Browserbase Function.

`browserbase.listFunctionVersions` lists immutable versions of one Browserbase Function. Inputs accept literal values or compatible signals. An optional second argument `{ account }` selects a named Browserbase binding.

## Example

```ts theme={null}
import { automation, onInvocation } from "automate.ax"
import { browserbase } from "automate.ax/browserbase"

export default automation("List Browserbase function versions", () => {
  onInvocation()
  browserbase.listFunctionVersions({
    functionId: "00000000-0000-4000-8000-000000000001",
    limit: 20,
  })
})
```

## Inputs

| Input        | Type     | Required | Default | Description      |
| ------------ | -------- | -------- | ------- | ---------------- |
| `functionId` | UUID     | Yes      | —       | Function ID.     |
| `limit`      | `number` | No       | `20`    | 1 through 100.   |
| `offset`     | `number` | No       | `0`     | Results to skip. |
