Steps For How to Integrate Instamojo Payment Gateway in Laravel 5

Step 1. Create Instamojo account

Go to https://www.instamojo.com/ and sign up account.

Step 2. At time of sign up use your valid email.

Step 3. Fill all required business details.

Step 4. Add your bank detail.

Step 5. Create route in laravel

We are required only two route to call controller.

Route::get('subscribe', [
    'as' => 'subscribe',
    'uses' => 'SigninController@SubscribProcess'
]);

Route::get('response', [
    'as' => 'response',
    'uses' => 'SigninController@Response'
]);

Step 6. SigninController with SubscribProcess function

In this step you can need X-Api-Key and X-Auth-Token this key provide Instamojo.

public function SubscribProcess()
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://www.instamojo.com/api/1.1/payment-requests/');
    curl_setopt($ch, CURLOPT_HEADER, FALSE);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
    curl_setopt($ch, CURLOPT_HTTPHEADER,
            array("X-Api-Key:",
          "X-Auth-Token:"));
    $payload = Array(
        'purpose' => 'First Subscribe',
        'amount' => '500',
        'phone' => '0123456789',
        'buyer_name' => Auth::user()->name,
        'redirect_url' => 'http://yoururltoredirect/response/',
        'send_email' => true,
        'webhook' => '',
        'send_sms' => true,
        'email' => Auth::user()->email,
        'allow_repeated_payments' => false
    );

    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($payload));
    $response = curl_exec($ch);
    curl_close($ch); 

     $json_decode  = json_decode($response, true);

     $query_update =  DB::table('tbl_users')
        ->where('id', Auth::user()->id)
        ->update([
            'payment_id'  => $json_decode['payment_request']['id'],
        ]);

   
    $long_url = $json_decode['payment_request']['longurl'];
    header("Location:$long_url");
    exit();
}

Step 7. SigninController with Response function

In this step instamojo check success payment and cancel payment response.

public function Response(Request $request)
{
    if(!empty($request->get('payment_request_id')))
    {
        $payment_id  = $request->get('payment_request_id');
        $getdetail = DB::table('tbl_users')
            ->where('id','=', Auth::user()->id)
            ->select('*')
            ->first();   
        if($payment_id == $getdetail->payment_id)
        {
             dd('Success Payment!');
        }
        else
        {
             dd('Due to some error please try again.');
        }
    }
    else
    {
         dd('Due to some error please try again.');
    }
}
