Checkout with Mercado Pago

This tutorial was written by Claude Code (an AI) and has not yet been reviewed. Follow along with caution. If the tutorial was helpful or a specific part was not clear/correct, please provide feedback at the bottom of the page. Thank you.

This guide covers integrating Mercado Pago with CoCart Preview API. Requires CoCart v4.6+ and a configured Mercado Pago payment gateway.

Overview

Mercado Pago integration with CoCart uses Checkout Bricks for a modular, secure, and customizable payment solution. This provides PCI compliance while supporting 15+ payment methods popular in Latin America, including PIX (Brazil), cards, installments, and digital wallets. Mercado Pago is the leading payment platform in Latin America, operating in Argentina, Brazil, Chile, Colombia, Mexico, Peru, and Uruguay.

Prerequisites

Before implementing Mercado Pago checkout, ensure you have:

Mercado Pago payment gateway configured in WooCommerce
Mercado Pago Public Key and Access Token
A valid cart with items added
Customer billing address information
Mercado Pago account (sandbox mode available)

Integration Flow

Load SDK

Initialize the Mercado Pago JavaScript SDK

Create Bricks Instance

Set up the Bricks Builder with your public key

Mount Card Payment Brick

Render the secure payment form

Collect Payment Data

Customer enters payment information in the Brick

Generate Payment Token

Submit Brick form to get payment token

Complete Checkout

Submit payment token to CoCart for processing

Step 1: Load Mercado Pago SDK

Include the SDK in your checkout page:

<!-- Load Mercado Pago SDK v2 -->
<script src="https://sdk.mercadopago.com/js/v2"></script>

The Mercado Pago SDK is always served over HTTPS and includes the latest security updates.

Step 2: HTML Structure

Create containers for the payment Brick and form:

<form id="checkout-form">
    <!-- Customer Information -->
    <div class="billing-section">
        <h3>Información de Facturación</h3>
        <input type="text" name="billing_first_name" placeholder="Nombre" required>
        <input type="text" name="billing_last_name" placeholder="Apellido" required>
        <input type="email" name="billing_email" placeholder="Email" required>
        <input type="tel" name="billing_phone" placeholder="Teléfono" required>
        <input type="text" name="billing_address_1" placeholder="Dirección" required>
        <input type="text" name="billing_city" placeholder="Ciudad" required>
        <input type="text" name="billing_state" placeholder="Estado/Provincia" required>
        <input type="text" name="billing_postcode" placeholder="Código Postal" required>
        <select name="billing_country" required>
            <option value="BR">Brasil</option>
            <option value="AR">Argentina</option>
            <option value="MX">México</option>
            <option value="CL">Chile</option>
            <option value="CO">Colombia</option>
            <option value="PE">Perú</option>
            <option value="UY">Uruguay</option>
        </select>
    </div>

    <!-- Payment Brick Container -->
    <div id="cardPaymentBrick_container"></div>

    <div id="mercadopago-error-message" class="error-message" style="display: none;"></div>
</form>

<!-- Status message container (shown after submission) -->
<div id="statusScreenBrick_container" style="display: none;"></div>

Step 3: Initialize Mercado Pago SDK

Set up the SDK with your public key:

async function setupMercadoPagoCheckout() {
    try {
        // Get payment context with public key
        const context = await createMercadoPagoPaymentContext();

        // Initialize Mercado Pago SDK
        const mp = new MercadoPago(context.public_key, {
            locale: context.locale || 'es-AR' // Language preference
        });

        // Create Bricks instance
        const bricksBuilder = mp.bricks();

        // Create and mount Card Payment Brick
        await createCardPaymentBrick(bricksBuilder, context);

        console.log('Mercado Pago checkout initialized successfully');

    } catch (error) {
        console.error('Mercado Pago setup error:', error);
        showError('Error al configurar el pago. Por favor, actualiza la página.');
    }
}

async function createMercadoPagoPaymentContext() {
    const cartKey = localStorage.getItem('cart_key');

    const response = await fetch('/wp-json/cocart/preview/checkout/payment-context', {
        method: 'POST',
        headers: {
            'Cart-Key': cartKey,
            'Content-Type': 'application/json',
        },
        body: JSON.stringify({
            payment_method: 'mercadopago'
        })
    });

    if (!response.ok) {
        const error = await response.json();
        throw new Error(error.message || 'Failed to create payment context');
    }

    const context = await response.json();

    // Context contains:
    // - public_key: Your Mercado Pago public key
    // - amount: Order amount
    // - locale: Preferred locale (es-AR, pt-BR, es-MX, etc.)
    // - currency: Currency code (ARS, BRL, MXN, etc.)

    return context;
}

Step 4: Create Card Payment Brick

Mount the payment form:

async function createCardPaymentBrick(bricksBuilder, context) {
    const form = document.getElementById('checkout-form');
    const formData = new FormData(form);
    const billingAddress = getBillingAddressFromForm(formData);

    const settings = {
        initialization: {
            amount: context.amount,
            payer: {
                email: billingAddress.email,
                firstName: billingAddress.first_name,
                lastName: billingAddress.last_name,
                identification: {
                    type: getIdentificationType(billingAddress.country),
                    number: '' // Customer will enter this
                }
            }
        },
        customization: {
            visual: {
                style: {
                    theme: 'default', // 'default', 'dark', 'bootstrap', 'flat'
                    customVariables: {
                        textPrimaryColor: '#000000',
                        textSecondaryColor: '#666666',
                        inputBackgroundColor: '#ffffff',
                        formBackgroundColor: '#f7f7f7',
                        baseColor: '#6a42d7',
                        borderRadius: '4px',
                        errorColor: '#e53e3e',
                        successColor: '#38a169'
                    }
                },
                hidePaymentButton: false,
                hideFormTitle: false
            },
            paymentMethods: {
                maxInstallments: context.max_installments || 12,
                minInstallments: 1,
                // Only allow credit cards (exclude debit if needed)
                types: {
                    excluded: [] // or ['debit_card'] to exclude debit
                }
            }
        },
        callbacks: {
            onReady: () => {
                console.log('Card Payment Brick ready');
            },
            onSubmit: async (formData) => {
                return await handleBrickSubmit(formData, billingAddress);
            },
            onError: (error) => {
                console.error('Brick error:', error);
                showError('Error en el formulario de pago');
            }
        }
    };

    // Create and mount the brick
    const cardPaymentBrickController = await bricksBuilder.create(
        'cardPayment',
        'cardPaymentBrick_container',
        settings
    );

    return cardPaymentBrickController;
}

// Helper to get identification type by country
function getIdentificationType(country) {
    const types = {
        'AR': 'DNI',
        'BR': 'CPF',
        'CL': 'RUT',
        'CO': 'CC',
        'MX': 'RFC',
        'PE': 'DNI',
        'UY': 'CI'
    };
    return types[country] || 'DNI';
}

Step 5: Handle Brick Submission

Process the payment data when Brick form is submitted:

async function handleBrickSubmit(brickFormData, billingAddress) {
    try {
        console.log('Brick submitted:', brickFormData);

        // Brick returns:
        // - token: Payment token
        // - paymentMethodId: Payment method (visa, master, etc.)
        // - issuerId: Card issuer ID
        // - installments: Number of installments
        // - identificationNumber: Customer ID number
        // - identificationType: ID type (CPF, DNI, etc.)

        // Prepare payment data for CoCart
        const paymentData = {
            token: brickFormData.token,
            payment_method_id: brickFormData.paymentMethodId,
            issuer_id: brickFormData.issuerId,
            installments: brickFormData.installments || 1,
            payer: {
                email: billingAddress.email,
                identification: {
                    type: brickFormData.identificationType,
                    number: brickFormData.identificationNumber
                }
            }
        };

        // Process checkout with CoCart
        const result = await processMercadoPagoCheckout(billingAddress, paymentData);

        // Show success status
        showStatusBrick(result, 'success');

        return result;

    } catch (error) {
        console.error('Payment processing error:', error);

        // Show error to user
        if (error instanceof MercadoPagoError) {
            showError(error.getDisplayMessage());
        } else {
            showError(error.message || 'Error al procesar el pago');
        }

        // Return error to brick
        throw error;
    }
}

async function processMercadoPagoCheckout(billingAddress, paymentData) {
    const cartKey = localStorage.getItem('cart_key');

    const checkoutData = {
        billing_address: billingAddress,
        payment_method: 'mercadopago',
        payment_data: paymentData
    };

    const response = await fetch('https://yoursite.com/wp-json/cocart/preview/checkout', {
        method: 'PUT',
        headers: {
            'Cart-Key': cartKey,
            'Content-Type': 'application/json',
        },
        body: JSON.stringify(checkoutData)
    });

    const result = await response.json();

    if (!response.ok) {
        // Handle specific Mercado Pago errors
        if (result.data?.gateway_error) {
            throw new MercadoPagoError(result.data.gateway_error);
        }
        throw new Error(result.message || `HTTP ${response.status}`);
    }

    return result;
}

// Custom error class
class MercadoPagoError extends Error {
    constructor(gatewayError) {
        super(gatewayError.message || 'Payment processing failed');
        this.code = gatewayError.code;
        this.cause = gatewayError.cause;
    }

    getDisplayMessage() {
        const errorMap = {
            '205': 'Ingresa el número de tu tarjeta',
            '208': 'Elige un mes',
            '209': 'Elige un año',
            '212': 'Ingresa tu documento',
            '213': 'Ingresa tu documento',
            '214': 'Ingresa tu documento',
            '220': 'Ingresa tu banco emisor',
            '221': 'Ingresa el nombre y apellido',
            '224': 'Ingresa el código de seguridad',
            'E301': 'Número de tarjeta inválido',
            'E302': 'Código de seguridad inválido',
            '316': 'Ingresa un nombre válido',
            '322': 'Tipo de documento inválido',
            '323': 'Verifica tu documento',
            '324': 'Documento inválido',

            'cc_rejected_bad_filled_card_number': 'Revisa el número de tarjeta',
            'cc_rejected_bad_filled_date': 'Revisa la fecha de vencimiento',

        };

        return errorMap[this.code] || this.message || 'Error al procesar el pago';
    }
}

Step 6: Show Status Brick

Display payment result to customer:

async function showStatusBrick(result, status) {
    // Hide checkout form
    document.getElementById('checkout-form').style.display = 'none';

    // Show status container
    const statusContainer = document.getElementById('statusScreenBrick_container');
    statusContainer.style.display = 'block';

    // Initialize SDK again for status brick
    const context = await createMercadoPagoPaymentContext();
    const mp = new MercadoPago(context.public_key);
    const bricksBuilder = mp.bricks();

    const settings = {
        initialization: {
            paymentId: result.payment_id || null,
            additionalInfo: {
                externalResourceUrl: result.payment_result?.redirect_url || null
            }
        },
        customization: {
            visual: {
                hideStatusDetails: false,
                hideTransactionDate: false,
                style: {
                    theme: 'default'
                }
            },
            backUrls: {
                error: window.location.href,
                return: result.payment_result?.redirect_url || window.location.href
            }
        },
        callbacks: {
            onReady: () => {
                console.log('Status Brick ready');
            },
            onError: (error) => {
                console.error('Status Brick error:', error);
            }
        }
    };

    await bricksBuilder.create('statusScreen', 'statusScreenBrick_container', settings);

    // Clear cart
    localStorage.removeItem('cart_key');

    // Auto-redirect after delay
    if (result.payment_result?.redirect_url) {
        setTimeout(() => {
            window.location.href = result.payment_result.redirect_url;
        }, 5000);
    }
}

Complete Integration Example

Here’s a complete working implementation:

class MercadoPagoCheckout {
    constructor() {
        this.mp = null;
        this.bricksBuilder = null;
        this.cardBrickController = null;
        this.context = null;
    }

    async initialize() {
        try {
            // Create payment context
            this.context = await this.createPaymentContext();

            // Initialize SDK
            this.mp = new MercadoPago(this.context.public_key, {
                locale: this.context.locale || 'es-AR'

                }
            },
            callbacks: {
                onReady: () => {
                    console.log('Card Payment Brick ready');

Advanced Features

PIX Payments (Brazil)

For instant PIX payments:

const pixBrickController = await bricksBuilder.create(
    'payment',
    'payment_container',
    {
        initialization: {
            amount: context.amount,
            preferenceId: '<PREFERENCE_ID>'
        },
        customization: {
            paymentMethods: {
                types: {
                    included: ['bank_transfer'],
                    excluded: ['credit_card', 'debit_card']
                }
            }
        }
    }
);

Installments

Configure installment options:

customization: {
    paymentMethods: {
        maxInstallments: 12,
        minInstallments: 1,
        creditCard: ['installments', 'credits'] // Payment types
    }
}

Wallet Integration

Enable Mercado Pago Wallet:

const walletBrickController = await bricksBuilder.create(
    'wallet',
    'wallet_container',
    {
        initialization: {
            preferenceId: '<PREFERENCE_ID>',
            redirectMode: 'modal' // or 'self' for redirect
        }
    }
);

Webhook Handling (IPN)

Mercado Pago sends notifications via IPN (Instant Payment Notification):

// Server-side webhook handler
app.post('/webhooks/mercadopago', async (req, res) => {
    const { type, data } = req.body;

    if (type === 'payment') {
        const paymentId = data.id;

        // Fetch payment details from Mercado Pago API
        const payment = await mercadopago.payment.get(paymentId);

        switch (payment.status) {
            case 'approved':
                await handlePaymentApproved(payment);
                break;
            case 'pending':
                await handlePaymentPending(payment);
                break;
            case 'rejected':
                await handlePaymentRejected(payment);
                break;
            case 'refunded':
                await handlePaymentRefunded(payment);
                break;
        }
    }

    res.sendStatus(200);
});

Error Handling

Handle common Mercado Pago errors:

function handleMercadoPagoErrors(error) {
    const errorMap = {
        '205': 'Card number required',
        '208': 'Invalid month',
        '209': 'Invalid year',
        '212': 'Document required',
        '213': 'Document type required',
        '214': 'Invalid document',
        'cc_rejected_bad_filled_card_number': 'Check card number',
        'cc_rejected_bad_filled_date': 'Check expiration date',
        'cc_rejected_bad_filled_security_code': 'Check security code',
        'cc_rejected_insufficient_amount': 'Insufficient funds',
        'cc_rejected_call_for_authorize': 'Must authorize with bank',
        'cc_rejected_card_disabled': 'Card inactive',
        'cc_rejected_duplicated_payment': 'Duplicate payment',
        'cc_rejected_high_risk': 'Payment rejected',
        'cc_rejected_max_attempts': 'Max attempts reached'
    };

    return errorMap[error.code] || error.message || 'Payment failed';
}

Troubleshooting

Common issues and solutions: Brick not loading: Verify SDK is loaded and public key is correct. Payment rejected: Check test card details match the scenario. IPN not received: Configure webhook URL in Mercado Pago dashboard. Installments not showing: Verify payment method supports installments. Currency mismatch: Ensure amount matches account currency.

Always test your Mercado Pago integration thoroughly using test mode before going live. Configure IPN/webhooks to handle asynchronous payment updates. Monitor your Mercado Pago dashboard for chargebacks and disputes. Implement proper error logging for debugging payment issues.
