## About

This is a wrapper that allows integrate [Checkout Bricks](https://www.mercadopago.com/developers/en/docs/checkout-bricks/landing), [Secure Fields](https://github.com/mercadopago/sdk-js/blob/main/docs/fields.md) and [Core Methods](https://github.com/mercadopago/sdk-js/blob/main/docs/core-methods.md), and **Fast Payment authentication** easily inside React projects.

<br />

## Prerequisites

Before starts verify if you have installed Node version `v16.20.2` or superior.

<br/>

## Installation

First, install SDK MercadoPago React:
`npm install @mercadopago/sdk-react`

<br/>

## Initialization

Start the instance of MercadoPago:

```jsx
import { initMercadoPago } from '@mercadopago/sdk-react';

initMercadoPago('YOUR_PUBLIC_KEY');
```

<br/>

## Checkout Bricks

Checkout Bricks are modular checkout components.
Below are examples of Brick implementations, for more information check the Examples folder.

> **Note**
> It's mandatory to have previously done the [Initialization step](#initialization)

### Card Payment Brick

Use CardPayment component inside your functional React:

```jsx
import { CardPayment } from '@mercadopago/sdk-react';

const App = () => {
  return (
    <CardPayment
      initialization={{ amount: AMOUNT }}
      onSubmit={async (param) => {
        console.log(param);
      }}
    />
  );
};
export default App;
```

<br/>

### Payment Brick

Use Payment component inside your functional React:

```jsx
import { Payment } from '@mercadopago/sdk-react';

const App = () => {
  return (
    <Payment
      initialization={{
        amount: AMOUNT,
        preferenceId: '<YOUR_PREFERENCE_ID>',
      }}
      onSubmit={async (param) => {
        console.log(param);
      }}
    />
  );
};
export default App;
```

<br/>

### Status Screen Brick

Use StatusScreen component inside your functional React:

```jsx
import { StatusScreen } from '@mercadopago/sdk-react';

const App = () => {
  return <StatusScreen initialization={{ paymentId: 'YOUR_PAYMENT_ID' }} />;
};
export default App;
```

<br/>

### Wallet Brick

Use Wallet component inside your functional React:

```jsx
import { Wallet } from '@mercadopago/sdk-react';

const App = () => {
  return <Wallet initialization={{ preferenceId: 'YOUR_PREFERENCE_ID' }} />;
};
export default App;
```

<br/>

### Brand Brick

Use Brand component inside your functional React:

```jsx
import { Brand } from '@mercadopago/sdk-react';

const App = () => {
  return <Brand />;
};
export default App;
```

<br/>

## Secure Fields

Secure Fields are input components that allow you to collect credit and debit card information safely, and allow you to get the PCI SAQ A certification.
The Secure Fields module also provides a method to get the card token safely without the need to store the card data.

> It's mandatory to have previously done the [Initialization step](#initialization)

## Fast Payment

> This feature is disabled by default, to enable, please contact the offical _Mercado Pago_ support via developer's website: www.mercadopago.com/developers

Fast Payment allows users to authenticate using their MercadoPago/MercadoLibre account and quickly access their saved payment methods for streamlined checkout experiences.

import { createAuthenticator } from '@mercadopago/sdk-react';

// Show authentication UI and get FastPaymentToken
try {
  const authenticator = await createAuthenticator('100.00', 'user@example.com');
  const fastPaymentToken = await authenticator.show({
    confirmationLocation: 'web',
  });
  console.log('FastPaymentToken:', fastPaymentToken);
} catch (error) {
  console.error(error.message, 'Error code:', error?.errorCode);
}
```

For a complete working example, see the `examples/fastPaymentFlow/` directory.
