Make my Own Payment Processor

You can create your own plugin for your own Payment Processor. Use one of the existing plugins as a an example.
Most processors rely on three functions: one to construct the plugin, one to create a form and one to handle the notification from the processor with results of the transaction.
Some are more complicated, requiring a call to get a session or transaction ID before proceeding.

Here are the basics.

1. Constructor:
   public function __construct(&$subject, $config){}
   This is PHP7 format, and it can contain a call to the php5 constructor. This will make it compatible with both versions.
   
   Example:
   public function __construct(&$subject, $config)
       {
           $this->plgMyMusePayment_Myprocessor($subject, $config);
       }
       
    function plgMyMusePayment_Myprocessor(&$subject, $config)  {
           parent::__construct($subject, $config);
    }
   
   
2. Create the form/button
   
   onBeforeMyMusePayment($shopper, $store, $order, $params, $Itemid=1){}
   
   Create a form with all the fields needed by your processor and a button to submit.
   It could include a call to a default template ("tmpl/default.php") which can be overridden in your master template:
   
   Example:
   $path = JPluginHelper::getLayoutPath('mymuse', 'payment_paypalpro');
   @ob_start();
   include $path;
   $html = @ob_get_clean();
   
   return $html;
   
   
3. Notification
   
   onMyMuseNotify($params)
   
   Most payment processors send a notification to your cart regarding the transaction. In PayPal it is called IPN (Instant Payment Notification).
   This will either confirm the transaction or generate an error.
   It must return a result array.
   
   Example:
   
           $result = array();
           $result['plugin']                 = "payment_myprocesor"; //name of the plugin
           $result['myorder']                 = 0; //must be >0 to trigger that it was this plugin
           $result['message_sent']         = 0; //must be >0 or tiggers error
           $result['message_received']     = 0; //must be >0 or tiggers error
           $result['order_found']            = 0; //must be >0 or tiggers error
           $result['order_verified']         = 0; //must be >0 or tiggers error
           $result['order_completed']         = 0; //must be >0 or tiggers error
           $result['order_number']            = 0; //must be >0 or tiggers error
           $result['order_id']                = 0; //must be >0 or tiggers error
           $result['payer_email']            = 0;
           $result['payment_status']        = 0;
           $result['txn_id']                = 0;
           $result['error']                = '';
