AuthnetJSON

Library that abstracts Authorize.Net's JSON APIs.

Requirements

• PHP 7.2+ (Support for PHP 7.2.0 - 8.*)
• cURL PHP Extension
• JSON PHP Extension
• An Authorize.Net account

Support for PHP versions less than 7.2 has been removed from the master branch. There is a PHP 5.6 compatible branch available for development and releases for 5.6 may continue to be made as long as it is feasible to do so.

Installation

Simply add a dependency on stymiee/authnetjson to your project's composer.json file if you use Composer to manage the dependencies of your project.

Here is a minimal example of a composer.json file that just defines a dependency on AuthnetJSON:

{
    "require": {
        "stymiee/authnetjson": "~4.1"
    }
}

Basic Usage

Using this library usually consists of three steps:

1. Initiate the library with the login credentials for your Authorize.Net account
2. Make the API call passing any required parameters as an array
3. Check for the results and use them appropriately

NOTE: If you are viewing any of the examples in a browser you will need to fill your Authorize.Net credentials in config.inc.php before usage

Simple usage:

The format of the array to be passed during the API call follows the structure outlined in Authorize.Net's Integration Guide.

Using the Authorize.Net Development Server

Authorize.Net provides a development environment for developers to test their integration against. To use this endpoint (as opposed to their production endpoint) set the optional third parameter of AuthnetApiFactory::getJsonApiHandler() to be 1 or use the built in class constant AuthnetApiFactory::USE_DEVELOPMENT_SERVER:

$json = AuthnetApiFactory::getJsonApiHandler(AUTHNET_LOGIN, AUTHNET_TRANSKEY, 
                                                AuthnetApiFactory::USE_DEVELOPMENT_SERVER);

Usage Examples

To help make how this library is used easier to understand example API calls are provided in the example directory. Examples for all of the current APIs calls are represented. You may need to make adjustments to get some to work as they may be dependent on valid values created from other API calls (i.e. a void will not work without a valid transaction ID).

Authorize and Capture (Basic)

Authorize and Capture (Full)

Create a Customer Profile

Create a Recurring Subscription

Get a List of Settled Batches

Get Transaction Detail From CIM API Calls

Some CIM API calls process an AUTH_CAPTURE transaction and return data similar to AIM AUTH_CAPTURE transactions. To access this information you can call AuthnetJsonResponse::getTransactionResponseField() using the field name or field number. For example, if you are looking for the transaction ID you can use:

or

Field name and number can be found in the Authorize.Net AIM Guide. Note that the field name has all spaces removed so TransactionID becomes TransactionID.

Create a Webhook

Validate and access a Webhook

If apache_request_headers()/getallheaders() are not available to you, you can will need to get the HTTP request headers and pass them as the third parameter to AuthnetWebhook().

Accept.js

To see examples of an Accept.js powered self hosted payment form, an Authorize.Net hosted payment form, and a hosted customer profile page, visit the Accept.js examples directory.

Debugging

To assist with debugging the __toString() method has been overridden to output important elements pertaining to the usage of this library. Simple echo your AuthnetJSON object to see:

• The API Login ID used
• The API transaction Key used
• The API endpoint the request was sent to
• The request JSON
• The response JSON
