}

A. Install Instamojo Package

composer require instamojo/instamojo-php

B. Open services.php file and add the following code into it, which is inside config/services.php directory:

'instamojo' => [
    'api_key'       => env('IM_API_KEY'),
    'auth_token'    => env('IM_AUTH_TOKEN'),
    'redirect_url'           => env('IM_URL'),
],

C. Make Model & Migration:

php artisan make:model Payment -m

D. Make Model & Migration:

public function up()
 {
 Schema::create('payments', function (Blueprint $table) {
 $table->increments('id');
 $table->string('i_payment_id');
 $table->string('user_id');
 $table->string('amount');
 $table->timestamps();
 });
 }

php artisan migrate

E. Create Controller:

php artisan make:controller PayController

F. Create Controller:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class PayController extends Controller
{

public function index()
{
return view('event');
}
public function pay(Request $request){

$api = new \Instamojo\Instamojo(
config('services.instamojo.api_key'),
config('services.instamojo.auth_token'),
config('services.instamojo.url')
);

try {
$response = $api->paymentRequestCreate(array(
"purpose" => "FIFA 16",
"amount" => $request->amount,
"buyer_name" => "$request->name",
"send_email" => true,
"email" => "$request->email",
"phone" => "$request->mobile_number",
"redirect_url" => "http://127.0.0.1:8000/pay-success"
));

header('Location: ' . $response['longurl']);
exit();
}catch (Exception $e) {
print('Error: ' . $e->getMessage());
}
}

public function success(Request $request){
try {

$api = new \Instamojo\Instamojo(
config('services.instamojo.api_key'),
config('services.instamojo.auth_token'),
config('services.instamojo.url')
);

$response = $api->paymentRequestStatus(request('payment_request_id'));

if( !isset($response['payments'][0]['status']) ) {
dd('payment failed');
} else if($response['payments'][0]['status'] != 'Credit') {
dd('payment failed');
} 
}catch (\Exception $e) {
dd('payment failed');
}
dd($response);
}
}

G. Make Router:

use App\Http\Controllers\PayController;


Route::get('event', [PayController::class, 'index']);
Route::post('pay', [PayController::class, 'pay']);
Route::get('pay-success', [PayController::class, 'success']);
