'providers' => [
  // ...
  
  Userdesk\Subscription\SubscriptionServiceProvider::class,
]

Add an alias within the aliases array found in config/app.php:

'aliases' => [

]

Configuration

There are two ways to configure laravel-subscription.

Option 1

Create configuration file for package using artisan command

$ php artisan vendor:publish --provider="Userdesk\Subscription\SubscriptionServiceProvider"

Option 2

Create configuration file manually in config directory config/subscription.php and put there code from below.

<?php
return [ 
  
  /*
  |--------------------------------------------------------------------------
  | Subscription Config
  |--------------------------------------------------------------------------
  */

  /*
  |--------------------------------------------------------------------------
  | Subscription Services
  |--------------------------------------------------------------------------
  |
  | This file is for storing the credentials for subscription services such
  | as Paypal, CCNow, PayFast, 2Checkout, and others. This file provides a sane
  | default location for this type of information, allowing packages
  | to have a conventional place to find your various credentials.
  |
  */
  'services' => [
    'paypal'=>[
      'email'=>'', 
      'logo'=>'',
      'auth'=>''
    ],
  ]

];

Credentials

Add your credentials to config/subscription.php (depending on which option of configuration you choose)

Usage

Basic usage

Just follow the steps below and you will be able to get a processor:

$paypal = Subscription::processor('Paypal');

Getting Processor Informationation

You can get basic Information for any processor by:

$processor = Subscription::processor($proc);

$info = $processor->info();

The value returned is a ProcessorInfo object. You can call getName, getLogo and getUrl methods on this processor to display Processor Name, Logo and Website Url for display purposes.

For getLogo method to work correctly you'll need to copy package assets to your project using

$ php artisan vendor:publish --provider="Userdesk\Subscription\SubscriptionServiceProvider"

Completing Subscription

Once you have the processor object you can call:

$processor = Subscription::processor($proc);

$processor->complete($id, $product, $consumer);

Complete method redirects to source processor so that your user can complete his payment.

$id is your unique Order ID. $product and $consumer are objects implementing SubscriptionProductContract and SubscriptionConsumerContract respectively.

A basic implementation of SubscriptionProductContract and SubscriptionConsumerContract are included with source in form of Classes\SubscriptionProduct and Classes\SubscriptionConsumer respectively.

Handling Processor Notifications

You can handle Processor Notifications and Processor Cart Return Data by forwarding them to ipn and pdt functions respectively.

Both these function excpects only one input with request data as array and returns TransactionResult object.

public function cartComplete(Request $request, $proc){
	$processor = Subscription::processor($proc);
	try{
		$result = $processor->pdt($request->all());
	}catch(TransactionException $exception){
		Log::error($exception->getMessage());	
	}
	
	if(!empty($result)){
		$cartId = $result->getId();
	  	if(!empty($cartId)){
	  		$action = $result->getAction();    
			if($action=='signup'){
				//Handle successful Signup
			}
		}else{
			Log::error('Cart Not Found For PDT', ['proc'=>$proc, 'data'=>$request->all()]);	
		}
	}
}

public function handleIpn(Request $request, $proc){
	$processor = Subscription::processor($proc);
	try{
	  	$result = $processor->ipn($request->all());
	}catch(Userdesk\Subscription\Exceptions\TransactionException $exception){
	  	//Handle Exceptions
	  	Log::error($exception->getMessage());  
	}

	if(!empty($result)){
	  	$cartId = $result->getId();
	  	if(!empty($cartId)){
		    $action = $result->getAction();        

		    if($action=='signup'){
		      //Handle Signup Code
		    }else if($action=='payment'){          
		      $transactionId = $result->getIdent();
		      $amount = $result->getAmount();
		      //Handle successful payments
		    }else if($action=='refund'){          
		      $transactionId = $result->getIdent();
		      $amount = $result->getAmount();
		      //Handle refunds
		    }else if($action=='cancel'){
		      //Handle cancellations;
		    }
		}else{
		    Log::error('Cart Not Found For IPN', ['proc'=>$proc, 'data'=>$request->all()]); 
		}
	}   
}

It is important to remember that IPN notifications are generally delivered via POST. So, you should add post method and remove csrf check for any route handling ipn notifications.
