Migrating from older versions

Since August 2018, the Authorize.Net API has been reorganized to be more merchant focused. AuthorizeNet AIM, ARB, CIM, Transaction Reporting and SIM classes have all been deprecated in favor of net\authorize\api . To see the full list of mapping of new features corresponding to the deprecated features, you can see


TLS 1.2

The Authorize.Net APIs only support connections using the TLS 1.2 security protocol. It's important to make sure you have new enough versions of all required components to support TLS 1.2. Additionally, it's very important to keep these components up to date going forward to mitigate the risk of any security flaws that may be discovered in your system or any libraries it uses.



Registration & Configuration

Use of this SDK and the Authorize.Net APIs requires having an account on our system. You can find these details in the Settings section. If you don't currently have a production Authorize.Net account and need a sandbox account for testing, you can easily sign up for one here.


To authenticate with the Authorize.Net API you will need to use your account's API Login ID and Transaction Key. If you don't have these values, you can obtain them from our Merchant Interface site. Access the Merchant Interface for production accounts at ( or sandbox accounts at (

Once you have your keys simply load them into the appropriate variables in your code, as per the below sample code dealing with the authentication part of the API request.

To set your API credentials for an API request:

    MerchantAuthenticationType merchantAuthenticationType  = new MerchantAuthenticationType() ;

You should never include your Login ID and Transaction Key directly in a file that's in a publically accessible portion of your website. A better practice would be to define these in a constants file, and then reference those constants in the appropriate place in your code.

Switching between the sandbox environment and the production environment

Authorize.Net maintains a complete sandbox environment for testing and development purposes. This sandbox environment is an exact duplicate of our production environment with the transaction authorization and settlement process simulated. By default, this SDK is configured to communicate with the sandbox environment. To switch to the production environment, set the appropriate environment constant using ApiOperationBase setEnvironment method. For example:


API credentials are different for each environment, so be sure to switch to the appropriate credentials when switching environments.

SDK Usage Examples and Sample Code

To get started using this SDK, it's highly recommended to download our sample code repository:

In that respository, we have comprehensive sample code for all common uses of our API:

Additionally, you can find details and examples of how our API is structured in our API Reference Guide:

The API Reference Guide provides examples of what information is needed for a particular request and how that information would be formatted. Using those examples, you can easily determine what methods would be necessary to include that information in a request using this SDK.

Create a Chase Pay Transaction

Use this method to authorize and capture a payment using a tokenized credit card number issued by Chase Pay. Chase Pay transactions are only available to merchants using the Paymentech processor.

The following information is required in the request:

  • The payment token,
  • The expiration date,
  • The cryptogram received from the token provider,
  • The tokenRequestorName,
  • The tokenRequestorId, and
  • The tokenRequestorEci.

When using the SDK to submit Chase Pay transactions, consider the following points:

  • tokenRequesterName must be populated with ”CHASE_PAY”
  • tokenRequestorId must be populated with the Token Requestor ID provided by Chase Pay services for each transaction during consumer checkout
  • tokenRequesterEci must be populated with the ECI Indicator provided by Chase Pay services for each transaction during consumer checkout

Building & Testing the SDK

Running the SDK Tests

  • Note: To properly run the unit tests, please reference the file, which is a simple properties file that holds the API credentials for testing the SDK.

Testing Guide

For additional help in testing your own code, Authorize.Net maintains a comprehensive testing guide that includes test credit card numbers to use and special triggers to generate certain responses from the sandbox environment.

Logging Sensitive Data

The Authorize.Net Java SDK uses Log4J framework for logging purposes and it can be enabled by keeping a configuration file in the resources folder of the application. A sample file has been provided as a reference.

The possible log levels are DEBUG, INFO, WARN, ERROR and FATAL. There is a new pattern layout introduced to mask sensitive data while logging and can be used with the application by providing the following configurations in the file:

// Default configuration which logs the entries in clear text 

log4j.appender.S.layout = org.apache.log4j.PatternLayout 
log4j.appender.R.layout = org.apache.log4j.PatternLayout 
// Configuration which masks the sensitive data in the log entries 

log4j.appender.S.layout = net.authorize.util.SensitiveFilterLayout 
log4j.appender.R.layout = net.authorize.util.SensitiveFilterLayout 

By default the logger comes with two appenders i.e console and file transport.

The list of sensitive fields which can be masked during logging are:

  • Card Number,
  • Card Code,
  • Expiration Date,
  • Name on Account,
  • Transaction Key, and
  • Account Number.

There is also a list of regular expressions which the sensitive logger uses to mask credit card numbers while logging. Further information on the sensitive data logging and regular expressions can be found at this location.
