Default rendering

To use a payment method (paymentMethods) of the "mercadoPago" type, a preference must be sent during Brick initialization, replacing the value <PREFERENCE_ID> by the ID of the preference created. Instructions for creating the preference are in the Enable payment with Mercado Pago section.

Once the configurations are created, enter the code below to render the Brick.

          
<div id="paymentBrick_container"></div>

        

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

<Payment
   initialization={initialization}
   customization={customization}
   onSubmit={onSubmit}
   onReady={onReady}
   onError={onError}
/>

        

The result of rendering the Brick should look like the image below.

To use a payment method (paymentMethods) of the "mercadoPago" type, a preference must be sent during Brick initialization, replacing the value <PREFERENCE_ID> by the ID of the preference created.

To create a preference in your backend, add the Mercado Pago SDK and the necessary credentials to your project to enable the preference usage:

          
<?php
// Mercado Pago SDK
require __DIR__ .  '/vendor/autoload.php';
// Add Your credentials
MercadoPago\SDK::setAccessToken('PROD_ACCESS_TOKEN');
?>

        

          
// Mercado Pago SDK
const mercadopago = require ('mercadopago');
// Add Your credentials
mercadopago.configure({
  access_token: 'PROD_ACCESS_TOKEN'
});

        

          
// Mercado Pago SDK
import com.mercadopago.MercadoPagoConfig;
// Add Your credentials
MercadoPagoConfig.setAccessToken("PROD_ACCESS_TOKEN");

        

          
# Mercado Pago SDK
require 'mercadopago'
# Add Your credentials
sdk = Mercadopago::SDK.new('PROD_ACCESS_TOKEN')

        

          
// Mercado Pago SDK
 using MercadoPago.Config;
 // Add Your credentials
MercadoPagoConfig.AccessToken = "PROD_ACCESS_TOKEN";

        

          
# Mercado Pago SDK
import mercadopago
# Add Your credentials
sdk = mercadopago.SDK("PROD_ACCESS_TOKEN")

        

Then set the preference according to your product or service.

The code examples below set the purpose of preference to wallet_purchase, but it is also possible to set it to onboarding_credits. Understand the difference between the two:

• wallet_purchase: the user must log in when redirected to his Mercado Pago account.

• onboarding_credits: after logging in, the user will see the pre-selected credit payment option in his Mercado Pago account.
