# Create Browserbase session

> Create a configurable cloud browser session and receive connection URLs.

`browserbase.createSession` creates a configurable cloud browser session and receives connection URLs. 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("Create Browserbase session", () => {
  onInvocation()
  browserbase.createSession({
    browserSettings: { recordSession: true },
    region: "us-west-2",
    timeout: 900,
  })
})
```

## Output

Returns the session record plus `connectUrl`, `seleniumRemoteUrl`, and `signingKey`.

Creating a session consumes browser capacity and is not replay-safe.
