Implement Payum/Laravel recurring payment

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:
