Authorize.Net .NET SDK

Travis CI Status Code Climate NuGet

Requirements

  • .NET 3.5 or later
  • Microsoft® Visual Studio 2008 or later
  • Nunit 2.6.3;
  • An Authorize.Net account (see Registration & Configuration section below)

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.

Installation

To install the AuthorizeNet .NET SDK, run the following command in the Package Manager Console:

PM> Install-Package AuthorizeNet

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.

Authentication

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 (https://account.authorize.net/) or sandbox accounts at (https://sandbox.authorize.net).

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:

ApiOperationBase<ANetApiRequest, ANetApiResponse>.MerchantAuthentication = new merchantAuthenticationType()
{
    name = "YOUR_API_LOGIN_ID",
    ItemElementName = ItemChoiceType.transactionKey,
    Item = "YOUR_TRANSACTION_KEY",
};

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 RunEnvironment method. For example:

// For PRODUCTION use
ApiOperationBase<ANetApiRequest, ANetApiResponse>.RunEnvironment = AuthorizeNet.Environment.PRODUCTION;

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.

Building & Testing the SDK

Running the SDK Tests

All the tests can be run against a stub backend using the USELOCAL run configuration.

Get a sandbox account at https://developer.authorize.net/sandbox/ Update app.config in the AuthorizeNetTest folder to run all the tests against your sandbox account

For reporting tests, go to https://sandbox.authorize.net/ under Account tab->Transaction Details API and enable it.

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.
