# BillingSetupElement

> Which payment methods ad spend bills against: a primary used first, and an optional backup for when it fails. Both are chosen from the methods already saved on the account, and picking one saves it immediately — there is no separate submit. Adding a card opens a card form over your page and returns to the slot that asked for it. The account's own balance appears alongside its cards wherever the account has one.

<Info>This page documents `@whop/elements@1.0.0-beta.0` and `@whop/elements-react@1.0.0-beta.0`.</Info>

*Pre-release, not yet part of a stable release.*

Mounts inside [`Ads`](/elements/beta/ads/overview). `accountId` and `accessToken` come from there. Pass props and callbacks through the create options or React props.

## Props

*This element takes no consumer props.*

## Events

Pass callbacks in the create options or React props.

### `onLoaderStart`

Runs after the loading skeleton first paints and before `onReady`.

**Signature:** `(() => void)`

### `onReady`

Runs after the element's first complete paint.

**Signature:** `(() => void)`

### `onError`

Runs when the element fails to load or crashes. The fallback remains visible. Use `code` for programmatic handling. `sourceKey` identifies a failed host-state source.

**Signature:** `((e: { message: string; code?: string | undefined; sourceKey?: string | undefined; }) => void)`

## Methods

Call these on the handle returned by `create`, or through a React `ref`.

### `mount`

Mounts the element in `target` and starts loading. React components mount themselves.

**Signature:** `(target: string | HTMLElement) => void`

### `destroy`

Removes the element and releases its frame and subscriptions. You can call it more than once. React removes the element automatically.

**Signature:** `() => void`

### `update`

Merges new props into the mounted element. In React, change the component props instead.

**Signature:** `(options: Partial<BillingSetupElementProps>) => void`

## Styling

This element doesn't expose class names for styling. Use `appearance` (theme, accent color, variables) to restyle it.
