# Boleto Bancário
source: https://developer.mastercard.com/mastercard-gateway/documentation/payment-methods/alt-pay-methods/a2a/boleto-bancario/index.md
Boleto Bancário is an e-commerce payment system used in Brazil that allows payers to purchase using either cash payments or through online banking payments. When the payer selects Boleto Bancário on the checkout page and proceeds with a cash payment, the payment details are displayed on screen and can be printed. The payer can then pay the amount required for the purchase at a Boleto Bacário location. For online banking payments, the payer enters the Boleto Bancário details, and reviews and authorizes the payment. In both cases, once the payment is made, you will be notified and the goods may be released to be shipped to the payer.
Boleto Bancário is a supported browser payment method in the Mastercard Gateway. This page describes integration details specific to Boleto Bancário. It is recommended that you read the [integration guidelines for browser payments](https://developer.mastercard.com/mastercard-gateway/documentation/payment-methods/imp-brow-pay-int/index.md) before building a Boleto Bancário integration.
Boleto Bancário browser payments are only supported for transactions in the USD currency.
Warning:
* Due to security reasons, the Boleto can only be accessed on the Mastercard Gateway for 48 hours or a maximum of five times, after which Boleto will no longer be available. The Boleto payment will expire as per your configuration.
* Boletos are always generated as PDF files. If you require these files to be available to payers for an extended period of time, you must save copies of them on your local server.

## How to Interpret the Transaction Result {#how-to-interpret-the-transaction-result}
The table below shows the transaction Response Codes for the possible scenarios that you may encounter after initiating a Boleto Bancário payment.
| Initiate Browser Payment Response | What This Means... |
|-----------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `response.gatewayCode=SUBMITTED` `result=SUCCESS` | Redirect the payer using the URL provided in the response. |
| **Retrieve Transaction/Retrieve Order Response** | **What This Means...** |
| `response.gatewayCode=APPROVED` `result=SUCCESS` | The payment is successful. |
| `response.gatewayCode=PENDING` `result=PENDING` | The Mastercard Gateway is waiting for a notification from the acquirer about the payment result. Try `RETRIEVE_TRANSACTION` again later or listen to notifications from the Mastercard Gateway. |
| `response.gatewayCode=CANCELLED` `result=FAILURE` | The payer has canceled the interaction for this payment. Offer the payer the option to try another payment method. |
| `response.gatewayCode=DECLINED` or `ACQUIRER_SYSTEM_ERROR` `result=FAILURE` | The payment was declined. Offer the payer the option to try another payment method. In the case of an `ACQUIRER_SYSTEM_ERROR` you may want to inquire with the acquirer the reason for payment failure, or you can try `RETRIEVE_TRANSACTION` again. |
| `response.gatewayCode=TIMED_OUT` `result=FAILURE` | Treat this as a declined payment. The Mastercard Gateway will attempt to ensure that the transaction is not successful or will revert the transaction. |
