To be able to receive payments, you need to add a form in the frontend that securely captures the payer's information.

If you already have a development that includes your own payment form, make sure to include Rapipago and Pago Fácil among the payment options you want to offer, as indicated below, and continue to the Get document types step.

If you do not have a payment form, add the one below to your project, including the identifier of the payment methods to be offered.

  <form id="form-checkout" action="/process_payment" method="post">
    <div>
      <div>
        <label for="payerFirstName">Nombre</label>
        <input id="form-checkout__payerFirstName" name="payerFirstName" type="text">
      </div>
      <div>
        <label for="payerLastName">Appelido</label>
        <input id="form-checkout__payerLastName" name="payerLastName" type="text">
      </div>
      <div>
        <label for="email">E-mail</label>
        <input id="form-checkout__email" name="email" type="text">
      </div>
      <div>
        <label for="identificationType">Tipo de documento</label>
        <select id="form-checkout__identificationType" name="identificationType" type="text"></select>
      </div>
      <div>
        <label for="identificationNumber">Número del documento</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="Nome do Produto">
        <br>
        <button type="submit">Pagar</button>
      </div>
    </div>
  </form>

To facilitate the correct entry of data in the payment form, it is necessary to obtain the possible document types to be accepted.

The function below will allow you to automatically populate the available options, thanks to the inclusion of the select element with the id: form-checkout__identificationType found in the form used as an example in the previous step.

If you already have a development that includes the retrieval of document types, as indicated below, proceed to the Submit payment step.

If you do not have this function, add the following to your project.

javascript
Copiar
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);
}

// Get Identification Types
(async function getIdentificationTypes () {
   try {
       const identificationTypes = await mp.getIdentificationTypes();
       const docTypeElement = document.getElementById('docType');

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

The payment submission must be made by creating an order that contains associated payment transactions.

To do this, send a POST with your production Access TokenPrivate key of the application created in Mercado Pago, that is used in the backend in development environments and when receiving real payments. You can access it through Your integrations > Application details > Production > Production credentials. and the required parameters listed below to the endpoint /v1/ordersAPI and execute the request.

If you wish, you can cancel a payment created for boleto bancário, as long as it is pending or in process; that is, with status=action_required.

Additionally, we recommend canceling payments that were not made by the established due date to avoid billing and reconciliation issues.

For more information, please consult the Refunds and cancellations section.
