To install the SDK, you must include script in your application's HTML or install a package on npm
<script src="https://sdk.mercadopago.com/js/v2"></script>or
npm install @mercadopago/sdk-js;
To start the SDK, you need to assign your public_key along with some options.
If you are using html reference:
const mp = new MercadoPago('YOUR_PUBLIC_KEY', {
locale: 'en-US',
})If you are using npm package:
import { loadMercadoPago } from '@mercadopago/sdk-js'
await loadMercadoPago();
const mp = new window.MercadoPago('YOUR_PUBLIC_KEY', {
locale: 'en-US',
})Use our APIs to build your own payment experience on your website or mobile application. From basic to advanced settings, control the entire experience.
There are multiple supported ways to integrate Checkout API. Ranging from the most simple integration, using Checkout Bricks, to integrating with the Core Methods, where the integrator has total control of the checkout experience.
