Pix - Integration configuration - Mercado Pago Developers

Pix

Pix is an instant electronic payment method offered by the Central Bank of Brazil to individuals and legal entities. Through the Checkout Transparente, it is possible to offer this payment option through QR code or payment code.

Important

In addition to the options available in this documentation, it is also possible to integrate payments with Pix using the Payment Brick. Check Default rendering documentation of Payment for more details.

To integrate payments with Pix, follow the steps below, but if you have already integrated card payments, start the integration from the Add payment form step.

Import MercadoPago.js

After creating the Pix Keys, it is necessary to capture data for payment. This capture is made by including the MercadoPago.js library in your project, followed by the payment form. Use the code below to import the library before adding the payment form.

          
<body>
  <script src="https://sdk.mercadopago.com/js/v2"></script>
</body>

          
npm install @mercadopago/sdk-js

Configure credentials

Credentials are unique keys with which we identify an integration in your account. They serve to capture payments in virtual stores and other applications securely.

This is the first step of a complete code structure that must be followed for the correct integration of payment via Pix. Pay attention to the blocks below to add to the codes as indicated.

          
<script>
  const mp = new MercadoPago("YOUR_PUBLIC_KEY");
</script>

          
import { loadMercadoPago } from "@mercadopago/sdk-js";

await loadMercadoPago();
const mp = new window.MercadoPago("YOUR_PUBLIC_KEY");

Add payment form

With the MercadoPago.js library included and the credentials configured, add the payment form below to your project to ensure secure capture of customer data.

          
<form id="form-checkout" action="/process_payment" method="post">
<div>
<div>
<label for="payerFirstName">Name</label>
<input id="form-checkout__payerFirstName" name="payerFirstName" type="text">
</div>
<div>
<label for="payerLastName">Surname</label>
<input id="form-checkout__payerLastName" name="payerLastName" type="text">
</div>
<div>
<label for="email">Email</label>
<input id="form-checkout__email" name="email" type="text">
</div>
<div>
<label for="identificationType">Document type</label>
<select id="form-checkout__identificationType" name="identificationType" type="text"></select>
</div>
<div>
<label for="identificationNumber">Document number</label>
<input id="form-checkout__identificationNumber" name="identificationNumber" type="text">
</div>
</div>

<div>
<div>
<input type="hidden" name="transactionAmount" id="transactionAmount" value="100">
<input type="hidden" name="description" id="description" value="Product Name">
<br>
<button type="submit">Pay</button>
</div>
</div>
</form>

Get document types

After configuring the credential and adding the payment form, it is necessary to obtain the types of documents that will be part of filling out the payment form.

By including the element of type select with the id: form-checkout__identificationType that is in the form, it will be possible to automatically fill in the available options when calling the following function:

          
(async function getIdentificationTypes() {
try {
const identificationTypes = await mp.getIdentificationTypes();
const identificationTypeElement = document.getElementById('form-checkout__identificationType');

createSelectOptions(identificationTypeElement, identificationTypes);
} catch (e) {
return console.error('Error getting identificationTypes: ', e);
}
})();

function createSelectOptions(elem, options, labelsAndKeys = { label: "name", value: "id" }) {
const { label, value } = labelsAndKeys;

elem.options.length = 0;

const tempOptions = document.createDocumentFragment();

options.forEach(option => {
const optValue = option[value];
const optLabel = option[label];

const opt = document.createElement('option');
opt.value = optValue;
opt.textContent = optLabel;

tempOptions.appendChild(opt);
});

elem.appendChild(tempOptions);
}

Send payment

When finalizing the inclusion of the payment form, it is necessary to send the buyer's email, type and document number, the payment method used (pix) and the value detail.

Important

When executing the APIs mentioned in this documentation, you may come across the attribute X-Idempotency-Key. Filling it out is important to ensure the execution and reexecution of requests without undesirable situations, such as duplicate payments, for example.

To configure payment with Pix, send a POST to the endpoint /v1/payments and execute the request or, if you prefer, make the request using our SDKs.

With Pix, you can also choose the period that the customer will have to pay for the purchase, defining the expiration date of the payment code sent after the order is placed.

Important

By default, the expiration date for payments with Pix is 24 hours, but you can change it by submitting the date_of_expiration field in the payment creation request. The configured date must be between 30 minutes and 30 days from the payment issue date.

Payment visualization

For the user to make the payment, you must choose the way to open it, which can be through a button or a QR code that must be rendered.

Select the option that best suits your business model and follow the steps described below.

Add Link or Button: When choosing to add a link or button for payment with Pix, the buyer will be directed to a new window containing all payment information, such as QR Code, Pix Copy and Paste and instructions for payment.

To offer this option, use the ticket_url attribute, which shows a Pix in a new window with all the QR Code, Pix Copy and Paste information and payment instructions.

          
<a href="https://www.mercadopago.com.br/payments/123456789/ticket?caller_id=123456&hash=123e4567-e89b-12d3-a456-426655440000" target="_blank">Pay with Pix</a>

Render QR code: It is possible to render the current QR code, which must be used only once, on the screen itself. In addition, it is also possible to add an option to copy and paste the payment code, which will allow you to carry out the transaction from an Internet Banking.

Follow the steps below to render the QR code and make copy and paste available.

Add qr_code_base64 to display the QR code.

          
<img src={`data:image/jpeg;base64,${qr_code_base64}`}/>

To present the option that will allow you to copy and paste the payment code, add the qr code as follows:

          
<label for="copy">Copy Hash:</label>
<input type="text" id="copiar" value={qr_code} readonly/>

Upon completing these steps, the QR code will have been rendered and will be displayed to the buyer at checkout.
