CardNumberElement - Whop Docs

This page documents @whop/elements@1.0.0-beta.0 and @whop/elements-react@1.0.0-beta.0.

Pre-release, not yet part of a stable release. Mounts inside CardFields, in Payments. Pass props and callbacks through the create options or React props.

import { WhopElements, Payments, CardFields, CardNumberElement } from "@whop/elements-react";
import { loadWhop } from "@whop/elements";

function Example() {
  return (
    <WhopElements elements={loadWhop()}>
      <Payments /* options */>
        <CardFields>
          <CardNumberElement />
        </CardFields>
      </Payments>
    </WhopElements>
  );
}

<script src="https://js.whop.cloud/elements/amber/elements.js" data-whop-elements></script>
<script type="module">
  const payments = window.WhopElements().payments.create({ /* options */ });
  const cardFields = payments.create('cardFields', { /* options */ });
  cardFields.create('cardNumber').mount('#payments-cardFields-cardNumber');
</script>

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<CardNumberElementProps>) => void

Styling

Style these parts through appearance.classes. Use camel case or kebab case for property names and include units. Page stylesheets can’t reach the element’s frame. The framework validates each declaration before injecting it.

Class	Targets
`.whop-CardField`	Card number, expiration, or security code field
`.whop-CardFieldError`	Card validation message
`.whop-CardFieldInput`	Bordered PCI input container
`.whop-CardFieldInputFocused`	Focused PCI input container
`.whop-CardFieldInputInvalid`	Invalid or incomplete PCI input container

const payments = whop.payments.create({
  appearance: {
    classes: {
      'whop-CardField': { borderRadius: '8px', fontWeight: '600' },
      'whop-CardFieldError': { borderRadius: '8px', fontWeight: '600' },
      'whop-CardFieldInput': { borderRadius: '8px', fontWeight: '600' }
    }
  }
});

// 5 classes use this shape
payments.update({
  appearance: { classes: { 'whop-CardField': { fontWeight: '700' } } }
});

In React, pass appearance to <Payments>. Set it globally with WhopElements({ appearance }).
