Mercado Pago SDK for Java

Maven Central APM

The official Mercado Pago Java client library.

💡 Requirements

Java 1.8 or later

📲 Installation

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

  1. Append MercadoPago dependencies to pom.xml
<dependency>
  <groupId>com.mercadopago</groupId>
  <artifactId>sdk-java</artifactId>
  <version>2.1.29</version>
</dependency>

  1. Run mvn install and that's all, you have Mercado Pago SDK installed.

  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.

🌟 Getting Started

Simple usage looks like:

import com.mercadopago.*;

import com.mercadopago.client.payment.PaymentClient;
import com.mercadopago.client.payment.PaymentCreateRequest;
import com.mercadopago.client.payment.PaymentPayerRequest;
import com.mercadopago.exceptions.MPApiException;
import com.mercadopago.exceptions.MPException;
import com.mercadopago.resources.payment.Payment;
import java.math.BigDecimal;

public class Example {

  public static void main(String[] args) {
    MercadoPagoConfig.setAccessToken("YOUR_ACCESS_TOKEN");

    PaymentClient client = new PaymentClient();

    PaymentCreateRequest createRequest =
        PaymentCreateRequest.builder()
            .transactionAmount(new BigDecimal(1000))
            .token("your_cardtoken")
            .description("description")
            .installments(1)
            .paymentMethodId("visa")
            .payer(PaymentPayerRequest.builder().email("dummy_email").build())
            .build();

    try {
      Payment payment = client.create(createRequest);
      System.out.println(payment);
    } catch (MPApiException ex) {
      System.out.printf(
          "MercadoPago Error. Status: %s, Content: %s%n",
          ex.getApiResponse().getStatusCode(), ex.getApiResponse().getContent());
    } catch (MPException ex) {
      ex.printStackTrace();
    }
  }
}

Per-request Configuration

All the request methods accept an optional MPRequestOptions object. With this you can set a custom access token, custom timeouts or even any custom headers you want, like an idempotency key for example.

public class Example {

  public static void main(String[] args) {
    PaymentClient client = new PaymentClient();

    Map<String, String> customHeaders = new HashMap<>();
    customHeaders.put("x-idempotency-key", "...");

    MPRequestOptions requestOptions =
        MPRequestOptions.builder()
            .accessToken("custom_access_token")
            .connectionRequestTimeout(2000)
            .connectionTimeout(2000)
            .socketTimeout(2000)
            .customHeaders(customHeaders)
            .build();

    try {
      Payment payment = client.create(createRequest, requestOptions);
      System.out.println(payment);
    } catch (MPException | MPApiException ex) {
      ex.printStackTrace();
    }
  }
}

SDK configurations

You can also set some customizations directly at MercadoPagoConfig class, for example set custom timeouts, a custom http client, log configurations, etc...

public class Example {

  public static void main(String[] args) {

    MercadoPagoConfig.setConnectionRequestTimeout(2000);
    MercadoPagoConfig.setSocketTimeout(2000);
    MercadoPagoConfig.setLoggingLevel(Level.FINEST);
  }
}

Custom Http Client

You can use a custom http client instead of using the default MPDefaultHttpClient by implementing the MPHttpClient interface.

public class CustomHttpClient implements MPHttpClient {
  //...
}
