Here we will show you all step by step and a very easy way to integrate Paypal.

Step 1: Create Paypal sandbox account

Very first step here you have one Paypal sandbox account for before going live integration you can test and check all Paypal card integration working fine there. Simple go to this link and signup/signin your Paypal sandbox account Paypal Developer Dashboard.

After singup/singin in your Paypal sandbox account then click on the Accounts menu which seen in left side. and then create one test bussined account and one buyer account. please seen following image for more information.

After create account then click on View/Edit Account link which you can seen under Manage Accounts. after click on this then open one popup and in this popup you can get your Sandbox API Credentials.

We need following Paypal Sandbox Credentials for make Paypal card payment request.

METHOD – The name of the API call you’re making.

USER – The API username

PWD – The API password

Step 2: Create route

After get you Sandbox API Credentials then create following two routes.

Route::get('paypal-payment-form', 'PaypalController@index')->name('paypal-payment-form'); Route::get('paypal-payment-form-submit', 'PaypalController@payment')->name('paypal-payment-form-submit');

Step 3: Create controller

After, done above two routes then we neet to create PaypalController.php file help of following artisan command.

php artisan make:controller PaypalController

After run this commant your PaypalController.php file automatic created on app/Http/Controllers folder. just open it and write following code into that file.

namespace App\Http\Controllers;
use Illuminate\Http\Request;
class PaypalController extends Controller

{

   public function index(Request $request)

    {

      return view(‘paypal-payment-form’);

   }
   public function payment(Request $request)

    {

       $request_params = array (

             ‘METHOD’ => ‘DoDirectPayment’,

             ‘USER’ => ‘laracode101_api1.gmail.com’,

             ‘PWD’ => ‘BQJBSMHVP8WCEETS’,

             ‘SIGNATURE’ => ‘AyVuUcpetZUWCXV.EHq.qRhxEb6.AChQnxfoM9w6UJXXRBh2cH1GUawh’,

             ‘VERSION’ => ‘85.0’,

             ‘PAYMENTACTION’ => ‘Sale’,

             ‘IPADDRESS’ => ‘127.0.0.1’,

             ‘CREDITCARDTYPE’ => ‘Visa’,

             ‘ACCT’ => ‘4032032452071167’,

             ‘EXPDATE’ => ‘072023’,

             ‘CVV2’ => ‘123’,

             ‘FIRSTNAME’ => ‘Yang’,

             ‘LASTNAME’ => ‘Ling’,

             ‘STREET’ => ‘1 Main St’,

             ‘CITY’ => ‘San Jose’,

             ‘STATE’ => ‘CA’,

             ‘COUNTRYCODE’ => ‘US’,

             ‘ZIP’ => ‘95131’,

             ‘AMT’ => ‘100.00’,

             ‘CURRENCYCODE’ => ‘USD’,

             ‘DESC’ => ‘Testing Payments Pro’

      );    

     

       $nvp_string = ‘’;    

       foreach($request_params as $var=>$val)

      {

         $nvp_string .= ‘&’.$var.‘=’.urlencode($val);

      }

    

        $curl = curl_init();    

        curl_setopt($curl, CURLOPT_VERBOSE, 0);    

        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);    

        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);    

        curl_setopt($curl, CURLOPT_TIMEOUT, 30);    

        curl_setopt($curl, CURLOPT_URL, ‘https://api-3t.sandbox.paypal.com/nvp’);    

        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);    

        curl_setopt($curl, CURLOPT_POSTFIELDS, $nvp_string);
       $result = curl_exec($curl);    

        curl_close($curl);  
       $data = $this->NVPToArray($result);
       if($data[‘ACK’] == ‘Success’) {

             # Database integration…

             echo “Your payment was processed success.”;

       } if ($data[‘ACK’] == ‘Failure’) {

             # Database integration…

             echo “Your payment was declined/fail.”;

       } else {

             echo “Something went wront please try again letter.”;

       }

   }
   public function  NVPToArray($NVPString)

    {

      $proArray = array();

      while(strlen($NVPString)) {

           // key

           $keypos= strpos($NVPString,‘=’);

           $keyval = substr($NVPString,0,$keypos);

           //value

           $valuepos = strpos($NVPString,‘&’) ? strpos($NVPString,‘&’): strlen($NVPString);

           $valval = substr($NVPString,$keypos+1,$valuepos-$keypos-1);
           $proArray[$keyval] = urldecode($valval);

           $NVPString = substr($NVPString,$valuepos+1,strlen($NVPString));

       }

       return $proArray;

   }

}

Here you can check following try response we will got from the Paypal REST API server.

Success response

Array

(

    [TIMESTAMP] => 2012-04-16T08:15:41Z

    [CORRELATIONID] => 9a652cbabfdd9

    [ACK] => Success

    [VERSION] => 85.0

    [BUILD] => 2764190

    [AMT] => 100.00

    [CURRENCYCODE] => USD

    [AVSCODE] => X

    [CVV2MATCH] => M

    [TRANSACTIONID] => 6VR832690S591564M

)

Fail response

    [TIMESTAMP] => 2012-04-16T08:18:46Z

    [CORRELATIONID] => 2db182b912a9

)

Step 4: Create blade file

After done controller file then we create one laravel blade HTML file which simple card payment design. Now we are create one simple blade file in resources/views/paypal-payment-form.blade.php file and here we are make very simple html layout for make card payment.

After done this step then your card payment layout look something like, please seen following sceenshot

@extends(‘layouts.app’)
@section(‘content’)

<div class=“container”>

   <div class=“row justify-content-center”>

       <div class=“col-md-4”>
