];

Usage

Following are some ways through which you can access the paypal provider:

// Import the class namespaces first, before using it directly
use Srmklive\PayPal\Services\ExpressCheckout;
use Srmklive\PayPal\Services\AdaptivePayments;

$provider = new ExpressCheckout;      // To use express checkout.
$provider = new AdaptivePayments;     // To use adaptive payments.

// Through facade. No need to import namespaces
$provider = PayPal::setProvider('express_checkout');      // To use express checkout(used by default).
$provider = PayPal::setProvider('adaptive_payments');     // To use adaptive payments.
 
// Through global helper functions
$provider = express_checkout();      // To use express checkout.
$provider = adaptive_payments();     // To use adaptive payments.

Set Currency

By default the currency used is USD. If you wish to change it, you may call setCurrency method to set a different currency before calling any respective API methods:

$provider->setCurrency('EUR')->setExpressCheckout($data);

Express Checkout

$data = [];
$data['items'] = [
    [
        'name' => 'Product 1',
        'price' => 9.99,
        'qty' => 1
    ],
    [
        'name' => 'Product 2',
        'price' => 4.99,
        'qty' => 2
    ]
];

$data['invoice_id'] = 1;
$data['invoice_description'] = "Order #$data[invoice_id] Invoice";
$data['return_url'] = url('/payment/success');
$data['cancel_url'] = url('/cart');

$total = 0;
foreach($data['items'] as $item) {
    $total += $item['price'];
}

$data['total'] = $total;

  • SetExpressCheckout

    $response = $provider->setExpressCheckout($data);

// Use the following line when creating recurring payment profiles (subscriptions)
$response = $provider->setExpressCheckout($data, true);

 // This will redirect user to PayPal
return redirect($response['paypal_link']);

  • GetExpressCheckoutDetails

    $response = $provider->getExpressCheckoutDetails($token);

  • DoExpressCheckoutPayment

    // Note that 'token', 'PayerID' are values returned by PayPal when it redirects to success page after successful verification of user's PayPal info.
$response = $provider->doExpressCheckoutPayment($data, $token, $PayerID);

  • RefundTransaction

    $response = $provider->refundTransaction($transactionid);

  • CreateBillingAgreement

    // The $token is the value returned from SetExpressCheckout API call
$response = $provider->createBillingAgreement($token);

  • CreateRecurringPaymentsProfile

    // The $token is the value returned from SetExpressCheckout API call
$startdate = Carbon::now()->toAtomString();
$profile_desc = !empty($data['subscription_desc']) ?
            $data['subscription_desc'] : $data['invoice_description'];
$data = [
    'PROFILESTARTDATE' => $startdate,
    'DESC' => $profile_desc,
    'BILLINGPERIOD' => 'Month', // Can be 'Day', 'Week', 'SemiMonth', 'Month', 'Year'
    'BILLINGFREQUENCY' => 12, // set 12 for monthly, 52 for yearly
    'AMT' => 10, // Billing amount for each billing cycle
    'CURRENCYCODE' => 'USD', // Currency code 
    'TRIALBILLINGPERIOD' => 'Day',  // (Optional) Can be 'Day', 'Week', 'SemiMonth', 'Month', 'Year'
    'TRIALBILLINGFREQUENCY' => 10, // (Optional) set 12 for monthly, 52 for yearly 
    'TRIALTOTALBILLINGCYCLES' => 1, // (Optional) Change it accordingly
    'TRIALAMT' => 0, // (Optional) Change it accordingly
];
$response = $provider->createRecurringPaymentsProfile($data, $token);

  • GetRecurringPaymentsProfileDetails

    $response = $provider->getRecurringPaymentsProfileDetails($profileid);

  • UpdateRecurringPaymentsProfile

    $response = $provider->updateRecurringPaymentsProfile($data, $profileid);

  • ManageRecurringPaymentsProfileStatus

    // Cancel recurring payment profile
$response = $provider->cancelRecurringPaymentsProfile($profileid);

// Suspend recurring payment profile
$response = $provider->suspendRecurringPaymentsProfile($profileid);

// Reactivate recurring payment profile
$response = $provider->reactivateRecurringPaymentsProfile($profileid);

Adaptive Payments

To use adaptive payments, you must set the provider to use Adaptive Payments:

PayPal::setProvider('adaptive_payments');

  • Pay

// Change the values accordingly for your application
$data = [
    'receivers'  => [
        [
            'email' => 'johndoe@example.com',
            'amount' => 10,
            'primary' => true,
        ],
        [
            'email' => 'janedoe@example.com',
            'amount' => 5,
            'primary' => false
        ]
    ],
    'payer' => 'EACHRECEIVER', // (Optional) Describes who pays PayPal fees. Allowed values are: 'SENDER', 'PRIMARYRECEIVER', 'EACHRECEIVER' (Default), 'SECONDARYONLY'
    'return_url' => url('payment/success'), 
    'cancel_url' => url('payment/cancel'),
];

$response = $provider->createPayRequest($data);

// The above API call will return the following values if successful:
// 'responseEnvelope.ack', 'payKey', 'paymentExecStatus'

Next, you need to redirect the user to PayPal to authorize the payment

$redirect_url = $provider->getRedirectUrl('approved', $response['payKey']);

return redirect($redirect_url);

Handling PayPal IPN

You can also handle Instant Payment Notifications from PayPal. Suppose you have set IPN URL to http://example.com/ipn/notify/ in PayPal. To handle IPN you should do the following:

  • First add the ipn/notify tp your routes file:

    Route::post('ipn/notify','PayPalController@postNotify'); // Change it accordingly in your application

  • Open App\Http\Middleware\VerifyCsrfToken.php and add your IPN route to $excluded routes variable.

    'ipn/notify'

  • Then in the controller where you are handling IPN, do the following:

    // Put this above controller definition
use Srmklive\PayPal\Traits\IPNResponse As PayPalIPN;

// Then add the following before function declaration
use PayPalIPN;

  • The above step saves the PayPal IPN response as ipn in session. Following is the code you can change to your own requirements for handling IPN:

    /**
 * Retrieve IPN Response From PayPal
 *
 * @param \Illuminate\Http\Request $request
 */
public function postNotify(Request $request)
{
    $post = [];
    $request_params = $request->all();

    foreach ($request_params as $key=>$value)
        $post[$key] = $value;

    $post['cmd'] = '_notify-validate';

    $response = $this->verifyIPN($post);

    session([
        'ipn' => $response
    ]);
}
