An SDK for Authorize.net, using Guzzle.

## Why not the official Authorize.net PHP SDK?

* Currently https://github.com/AuthorizeNet/sdk-php is licensed under a proprietary license.
* It is not PSR-4.
* Too many dependencies.

## Dependencies

PHP version >= 7.3 is required.

The following PHP extensions are required:
* json
* simplexml
* xmlwrite

This library uses Guzzle, v6 minimum.

## Testing

### PHPUnit

Run `composer test`, or `./vendor/bin/phpunit -c phpunit.xml.dist`
