This library provides developers with a simple set of bindings to help you integrate Mercado Pago API to a website and start receiving payments.

The SDK Supports NodeJS version 16 or higher.

First time using Mercado Pago? Create your Mercado Pago account, if you don’t have one already.

1. Install NodeJS SDK for MercadoPago running in command line:

$ npm install --save mercadopago

2. Copy the access_token in the credentials section of the page and replace YOUR_ACCESS_TOKEN with it.

That's it! Mercado Pago SDK has been successfully installed.

Simple usage looks like:

// Step 1: Import the parts of the module you want to use
import { MercadoPagoConfig, Payment } from 'mercadopago';

// Step 2: Initialize the client object
const client = new MercadoPagoConfig({ accessToken: 'access_token', options: { timeout: 5000, idempotencyKey: 'abc' } });

// Step 3: Initialize the API object
const payment = new Payment(client);

// Step 4: Create the request object
const body = {
	transaction_amount: 12.34,
	description: '<DESCRIPTION>',
	payment_method_id: '<PAYMENT_METHOD_ID>',
	payer: {
		email: '<EMAIL>'
	},
};

// Step 5: Create request options object - Optional
const requestOptions = {
	idempotencyKey: '<IDEMPOTENCY_KEY>',
};

// Step 6: Make the request
payment.create({ body, requestOptions }).then(console.log).catch(console.log);

Import MercadoPagoConfig and API objects from the MercadoPago module.

import { MercadoPagoConfig, Payment } from 'mercadopago';

Initialize the client object, passing the following:

• accessToken: Application's private key.
• options: These are optional fields,
  • timeout: Are the timeout of requests
  • idempotencyKey: Idempotency Is for retrying requests without accidentally performing the same operation twice

For example:

const client = new MercadoPagoConfig({ accessToken: 'access_token', options: { timeout: 5000, idempotencyKey: 'abc' } });

Initialize the API object you want to use, passing the client object from the previous step.

const payment = new Payment(client);

Create a the request object. For example, for a request to the /v1/payments endpoint:

const body = {
	transaction_amount: 12.34,
	description: '<DESCRIPTION>',
	payment_method_id: '<PAYMENT_METHOD_ID>',
	payer: {
		email: '<EMAIL>'
	},
};

Use the API object's method to make the request. For example, to make a request to the /v1/payments endpoint using the payment object:

payment.create({ body }).then(console.log).catch(console.log);
