Download the PHP package versa/maxipago without Composer

Introduction

This PHP library allows for easy integration with the maxiPago! Smart Payments API. Our payment platform allows online merchants to accept payments in many countries in Latin America and the US and includes such functionalities as Automated Recurring Billing, "Single-Click" payments, Online Returns, Credit Card Payment Reconciliation, Fraud Tools and more. You can find out more about maxiPago! by visiting www.maxipago.com.

This library has all the functionalities currently available through our XML-based API and can be freely copied and used by Merchants and developers.

You can get a more comprehensive view of our API by looking at our documentation, which can be downloaded here. If you are looking for a hosted payment page solution, please see the section smartPages! in the documentation.

Available transaction types

• Authorization: checks if the credit card used is valid (number, security code and expiration date) and if the card holder has sufficient funds for that purchase.

• Capture: confirms the authorization previously made and completes the transaction. If the transaction is never captured the Merchant does not receive the funds and the Card Holder is never charged.

Separating the authorization and capture in two different moments is an excellent way to check if you have the purchased items in stock or to run a fraud check, while still guaranteeing payment.

• Sale: combines the authorization and the capture in a single request. When performing a Sale we send the credit card for authorization and immediately capture that transaction, if approved.

• Void: cancels the transaction and no money is charged from the buyer. You can only void a transaction until 11:59pm of the day of capture.

• Return: reverses a credit card transaction, taking funds from the Merchant and giving them back to the buyer. This is a financial operation that might take a few days to be completed, depending on your credit card processor.

• Recurring: schedules a credit card transaction to be charged at a specific interval, defined by the Merchant.

• Card On File: saves a card in our system and returns a unique token, which can be used to process future transactions. This allows the implementation of "single-click" payments.

• Boleto: (Brazil only) Transactions made with Boletos are different than credit card purchases. This creates a boleto and returns an URL to the buyer to access the boleto payment slip. It can be accessed at any time before the boleto expiration and up to 60 days after it has expired.

Installation and setup

The library has been tested on PHP 5.1.6 and up and consists of the following files:

Copy /lib/maxipago/ to your local server. In your code, include the maxiPago.php file, which checks the minimum requirements and includes the other necessary files:

Now, create a new object from the maxiPago class:

Environment and Credentials

In order to send requests you will need valid Merchant Credentials. They can be obtained with our Customer Support team.

maxiPago! provides a fully functional sandbox environment to simulate the transaction responses. You need to set the environment the transactions will be sent to, which can be done by sending either "TEST" or "LIVE".

To set the credentials and environment used to process requests:

Logging and Debug Mode

In June 2013 Kenny Katzgrau's KLogger was added to this lib, allowing merchants to automatically log the transactions' request and response, following PCI compliance.

To enable logging use the setLogger() method, making sure your log file directory permissions are correct. The default logger level is INFO:

The Debug Mode prints the request and response XML's so you can easily identify any issues with the request. In order to enable debug use the setDebug() method:

Request

To send a request to maxiPago! you need to call one of the methods listed above, passing an array with the request parameters, as such:

Response

There are methods to get each piece of information from the response. However, you can also call the getResult() method to retrieve all fields in the response as an array:
