This repository contains working code samples which demonstrate PHP integration with the Authorize.Net PHP SDK.

The samples are organized into categories and common usage examples, like our API Reference Guide. The API Reference Guide is an interactive reference for the Authorize.Net API. It explains the request and response parameters for each API method and has embedded code windows to allow you to send actual requests right within the API Reference Guide.

The samples are completely independent and self-contained. You can analyze them to get an understanding of how a particular method works, or you can use the snippets as a starting point for your own project.

You can also run each sample directly from the command line.

• Clone this repository:

    $ git clone https://github.com/AuthorizeNet/sample-code-php.git

• Run composer with the "update" option in the root directory of the repository.

    $ composer update

• Run the individual samples by name. For example:

    $ php PaymentTransactions/[CodeSampleName]

e.g.

    $ php PaymentTransactions/charge-credit-card.php

Note: If during "composer update", you get the error "composer failed to open stream invalid argument", go to your php.ini file (present where you have installed PHP), and uncomment the following lines:

extension=php_openssl.dll
extension=php_curl.dll

On Windows systems, you also have to uncomment:

extension_dir = "ext"

Then run composer update again. You might have to restart your machine before the changes take effect.

Authorize.Net provides a custom SPL autoloader. Download the SDK and point to its autoload.php file:

require 'path/to/anet_php_sdk/autoload.php';

Authorize.Net is phasing out the MD5 based transHash element in favor of the SHA-512 based transHashSHA2. The setting in the Merchant Interface which controlled the MD5 Hash option is no longer available, and the transHash element will stop returning values at a later date to be determined. For information on how to use transHashSHA2, see the [Transaction Hash Upgrade Guide] (https://developer.authorize.net/support/hash_upgrade/).
