Implement Payum/Laravel recurring payment - php

Question

I have some issues trying to get this working, I've implemented the checkout express (or seems to be) successfully, but also my system needs subscription option, following this example.
Now, my problem is that in Laravel you cannot simply put some random files, so I'm trying to do it in the correct way, sadly, there is no documentation of the classes and methods including on the library.
I've created some functions within controllers (I don't know if this the right way) the problem I'm facing now is trying to createRecurringPayment() to apply the desired amount of the recurring payment, is the final step I guess.
Thanks for yout help.
app/controllers/PaypalController.php
public function prepareExpressCheckout(){
$storage = $this->getPayum()->getStorage('Payum\Core\Model\ArrayObject');
$details = $storage->createModel();
$details['PAYMENTREQUEST_0_CURRENCYCODE'] = 'USD';
$details['PAYMENTREQUEST_0_AMT'] = 1.23;
$storage->updateModel($details);
$captureToken = $this->getTokenFactory()->createCaptureToken('paypal_es', $details, 'payment_done');
$details['RETURNURL'] = $captureToken->getTargetUrl();
$details['CANCELURL'] = $captureToken->getTargetUrl();
$storage->updateModel($details);
return \Redirect::to($captureToken->getTargetUrl());
}
public function prepareSubscribe(){
$storage = $this->getPayum()->getStorage('Payum\Core\Model\ArrayObject');
$details = $storage->createModel();
$details['PAYMENTREQUEST_0_AMT'] = 0;
$details['L_BILLINGTYPE0'] = Api::BILLINGTYPE_RECURRING_PAYMENTS;
$details['L_BILLINGAGREEMENTDESCRIPTION0'] = "Suscripción por X meses";
$details['NOSHIPPING'] = 1;
$storage->updateModel($details);
$captureToken = $this->getTokenFactory()->createCaptureToken('paypal_es', $details, 'payment_done');
$storage->updateModel($details);
return \Redirect::to($captureToken->getTargetUrl());
}
public function createRecurringPayment(){
$payum_token = Input::get('payum_token');
$request = \App::make('request');
$request->attributes->set('payum_token', $payum_token);
$token = ($request);
//$this->invalidate($token);
$agreementStatus = new GetHumanStatus($token);
$payment->execute($agreementStatus);
if (!$agreementStatus->isSuccess()) {
header('HTTP/1.1 400 Bad Request', true, 400);
exit;
}
$agreementDetails = $agreementStatus->getModel();
$storage = $this->getPayum()->getStorage('Payum\Core\Model\ArrayObject');
$recurringPaymentDetails = $storage->createModel();
$recurringPaymentDetails['TOKEN'] = $agreementDetails['TOKEN'];
$recurringPaymentDetails['DESC'] = 'Subscribe to weather forecast for a week. It is 0.05$ per day.';
$recurringPaymentDetails['EMAIL'] = $agreementDetails['EMAIL'];
$recurringPaymentDetails['AMT'] = 0.05;
$recurringPaymentDetails['CURRENCYCODE'] = 'USD';
$recurringPaymentDetails['BILLINGFREQUENCY'] = 7;
$recurringPaymentDetails['PROFILESTARTDATE'] = date(DATE_ATOM);
$recurringPaymentDetails['BILLINGPERIOD'] = Api::BILLINGPERIOD_DAY;
$payment->execute(new CreateRecurringPaymentProfile($recurringPaymentDetails));
$payment->execute(new Sync($recurringPaymentDetails));
$doneToken = $this->createToken('paypal_es', $recurringPaymentDetails, 'payment_done');
return \Redirect::to($doneToken->getTargetUrl());
}

I have found the problem. It is with the parameters we pass to the create recurring payment function. Here are functions for agreement and payment creation. It should work fine.
<?php
namespace App\Http\Controllers;
use Payum\Core\Request\GetHumanStatus;
use Payum\LaravelPackage\Controller\PayumController;
use Payum\Paypal\ExpressCheckout\Nvp\Api;
use Payum\Core\Request\Sync;
use Payum\Paypal\ExpressCheckout\Nvp\Request\Api\CreateRecurringPaymentProfile;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
class PayPalController extends PayumController {
public function prepareSubscribeAgreement() {
$storage = $this->getPayum()->getStorage('Payum\Core\Model\ArrayObject');
$details = $storage->create();
$details['PAYMENTREQUEST_0_AMT'] = 0;
$details['L_BILLINGTYPE0'] = Api::BILLINGTYPE_RECURRING_PAYMENTS;
$details['L_BILLINGAGREEMENTDESCRIPTION0'] = "Weather subscription";
//$details['NOSHIPPING'] = 1;
$storage->update($details);
$captureToken = $this->getPayum()->getTokenFactory()->createCaptureToken('paypal_ec', $details, 'paypal_subscribe');
return \Redirect::to($captureToken->getTargetUrl());
}
public function createSubscribePayment(Request $request) {
$request->attributes->set('payum_token', $request->input('payum_token'));
$token = $this->getPayum()->getHttpRequestVerifier()->verify($request);
$gateway = $this->getPayum()->getGateway($token->getGatewayName());
$agreementStatus = new GetHumanStatus($token);
$gateway->execute($agreementStatus);
if (!$agreementStatus->isCaptured()) {
header('HTTP/1.1 400 Bad Request', true, 400);
exit;
}
$agreement = $agreementStatus->getModel();
$storage = $this->getPayum()->getStorage('Payum\Core\Model\ArrayObject');
$recurringPayment = $storage->create();
$recurringPayment['TOKEN'] = $agreement['TOKEN'];
$recurringPayment['PAYERID'] = $agreement['PAYERID'];
$recurringPayment['PROFILESTARTDATE'] = date(DATE_ATOM);
$recurringPayment['DESC'] = $agreement['L_BILLINGAGREEMENTDESCRIPTION0'];
$recurringPayment['BILLINGPERIOD'] = Api::BILLINGPERIOD_DAY;
$recurringPayment['BILLINGFREQUENCY'] = 7;
$recurringPayment['AMT'] = 0.05;
$recurringPayment['CURRENCYCODE'] = 'USD';
$recurringPayment['COUNTRYCODE'] = 'US';
$recurringPayment['MAXFAILEDPAYMENTS'] = 3;
$gateway->execute(new CreateRecurringPaymentProfile($recurringPayment));
$gateway->execute(new Sync($recurringPayment));
$captureToken = $this->getPayum()->getTokenFactory()->createCaptureToken('paypal_ec', $recurringPayment, 'payment_done');
return \Redirect::to($captureToken->getTargetUrl());
}
public function done(Request $request) {
/** #var Request $request */
//$request = \App::make('request');
$request->attributes->set('payum_token', $request->input('payum_token'));
$token = $this->getPayum()->getHttpRequestVerifier()->verify($request);
$gateway = $this->getPayum()->getGateway($token->getGatewayName());
$gateway->execute($status = new GetHumanStatus($token));
return \Response::json(array(
'status' => $status->getValue(),
'details' => iterator_to_array($status->getFirstModel())
));
}
}
The routes:
Route::get('paypal/agreement', 'PayPalController#prepareSubscribeAgreement');
Route::get('paypal/subscribe', [
'as' => 'paypal_subscribe',
'uses' => 'PayPalController#createSubscribePayment'
]);
Route::get('paydone', [
'as' => 'payment_done',
'uses' => 'PayPalController#done'
]);
Simply open www.example.com/paypal/agreement and it should take you to PayPal

In my project I used the following library and it helped me alot:
https://github.com/amirduran/duranius-paypal-rest-api-php-library
Here are some features:
Easy to install - Just one file
Library is implemented as PHP class
It supports Recurring Payments It supports ExpressCheckout payments
All available PayPal API methods are wrapped in belonging methods
Well documented

Here is my Pay Pal REST API code.

curl_setopt($ch, CURLOPT_URL, 'https://api.sandbox.paypal.com/v1/billing/subscriptions');

}
curl_close($ch);
$payment_id = json_decode($result);

//save data in database
$payment = new Subscription();

$payment->save();
return response()->json(['status' => true,'message'=>'Payment has been successfully Done','data'=>$payment]);
It's working fine for me.
