How to implement quickbooks online api in laravel 5.2

Hi, Today we will learn how to integrate quickbooks online in laravel 5.2.

The very first thing we'll have to do is register our app with Intuit. When we do this, Intuit will give us these variables:

app token
consumer secret
consumer key

The installation
Add this to your composer.json.
"require": {  
    "consolibyte/quickbooks": "^3.1"  
},

This will give us a page in root folder, QuickBooks.php. Include this page in app/config/app.php.

require_once '../QuickBooks.php';

In your .env file add the following configuration value:

QUICKBOOK_TOKEN = 95555248baf11b43fbb944ab97de9134ad85
QBO_OAUTH_CONSUMER_KEY = your consumer key
QBO_CONSUMER_SECRET = your consumer secret
QBO_SANDBOX = true
QBO_OAUTH_URL = http://yourdomain.com/qbo/oauth
QBO_SUCCESS_URL = http://yourdomain.com/qbo/success
QBO_MENU_URL = http://yourdomain.com/docs/partner_platform/example_app_ipp_v3/menu.php
QBO_DSN = mysqli://username:password@localhost/yourdbname
QBO_ENCRYPTION_KEY = bcde1234
QBO_USERNAME = DO_NOT_CHANGE_ME
QBO_TENANT = 12345

Now make a controller in app/Http/Controllers

QuickBookController.php.

Write following code to your controller:

<?php

namespace App\Http\Controllers;
use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;

class QuickBookController extends Controller
{

    private $IntuitAnywhere;
    private $context;
    private $realm;

    public function __construct(){
        if (!\QuickBooks_Utilities::initialized(env('QBO_DSN'))) {
            // Initialize creates the neccessary database schema for queueing up requests and logging
            \QuickBooks_Utilities::initialize(env('QBO_DSN'));
        }
        $this->IntuitAnywhere = new \QuickBooks_IPP_IntuitAnywhere(env('QBO_DSN'), env('QBO_ENCRYPTION_KEY'), env('QBO_OAUTH_CONSUMER_KEY'), env('QBO_CONSUMER_SECRET'), env('QBO_OAUTH_URL'), env('QBO_SUCCESS_URL'));
    }
    public function  qboConnect(){


        if ($this->IntuitAnywhere->check(env('QBO_USERNAME'), env('QBO_TENANT')) && $this->IntuitAnywhere->test(env('QBO_USERNAME'), env('QBO_TENANT'))) {
            // Set up the IPP instance
            $IPP = new \QuickBooks_IPP(env('QBO_DSN'));
            // Get our OAuth credentials from the database
            $creds = $this->IntuitAnywhere->load(env('QBO_USERNAME'), env('QBO_TENANT'));
            // Tell the framework to load some data from the OAuth store
            $IPP->authMode(
                \QuickBooks_IPP::AUTHMODE_OAUTH,
                env('QBO_USERNAME'),
                $creds);

            if (env('QBO_SANDBOX')) {
                // Turn on sandbox mode/URLs
                $IPP->sandbox(true);
            }
            // This is our current realm
            $this->realm = $creds['qb_realm'];
            // Load the OAuth information from the database
            $this->context = $IPP->context();

            return true;
        } else {
            return false;
        }
    }

    public function qboOauth(){
        if ($this->IntuitAnywhere->handle(env('QBO_USERNAME'), env('QBO_TENANT')))
        {
            ; // The user has been connected, and will be redirected to QBO_SUCCESS_URL automatically.
        }
        else
        {
            // If this happens, something went wrong with the OAuth handshake
            die('Oh no, something bad happened: ' . $this->IntuitAnywhere->errorNumber() . ': ' . $this->IntuitAnywhere->errorMessage());
        }
    }

    public function qboSuccess(){
        return view('qbo_success');
    }

    public function qboDisconnect(){
        $this->IntuitAnywhere->disconnect(env('QBO_USERNAME'), env('QBO_TENANT'),true);
        return redirect()->intended("/yourpath");// afer disconnect redirect where you want

    }

    public function createCustomer(){

        $CustomerService = new \QuickBooks_IPP_Service_Customer();

        $Customer = new \QuickBooks_IPP_Object_Customer();
        $Customer->setTitle('Ms');
$Customer->setGivenName('Shannon');
$Customer->setMiddleName('B');
$Customer->setFamilyName('Palmer');
$Customer->setDisplayName('Shannon B Palmer ' . mt_rand(0, 1000));
        // Terms (e.g. Net 30, etc.)
        $Customer->setSalesTermRef(4);

        // Phone #
        $PrimaryPhone = new \QuickBooks_IPP_Object_PrimaryPhone();
        $PrimaryPhone->setFreeFormNumber('860-532-0089');
$Customer->setPrimaryPhone($PrimaryPhone);

        // Mobile #
        $Mobile = new \QuickBooks_IPP_Object_Mobile();
        $Mobile->setFreeFormNumber('860-532-0089');
$Customer->setMobile($Mobile);

        // Fax #
        $Fax = new \QuickBooks_IPP_Object_Fax();
        $Fax->setFreeFormNumber('860-532-0089');
$Customer->setFax($Fax);

        // Bill address
        $BillAddr = new \QuickBooks_IPP_Object_BillAddr();
        $BillAddr->setLine1('72 E Blue Grass Road');
$BillAddr->setLine2('Suite D');
$BillAddr->setCity('Mt Pleasant');
$BillAddr->setCountrySubDivisionCode('MI');
$BillAddr->setPostalCode('48858');
$Customer->setBillAddr($BillAddr);

        // Email
        $PrimaryEmailAddr = new \QuickBooks_IPP_Object_PrimaryEmailAddr();
        $PrimaryEmailAddr->setAddress('support@consolibyte.com');
        $Customer->setPrimaryEmailAddr($PrimaryEmailAddr);

        if ($resp = $CustomerService->add($this->context, $this->realm, $Customer))
        {
            //print('Our new customer ID is: [' . $resp . '] (name "' . $Customer->getDisplayName() . '")');
            //return $resp;
            //echo $resp;exit;
            //$resp = str_replace('{','',$resp);
            //$resp = str_replace('}','',$resp);
            //$resp = abs($resp);
            return $this->getId($resp);
        }
        else
        {
            //echo 'Not Added qbo';
            print($CustomerService->lastError($this->context));
        }
    }

    public function addItem(){
        $ItemService = new \QuickBooks_IPP_Service_Item();

        $Item = new \QuickBooks_IPP_Object_Item();

        $Item->setName('My Item');
$Item->setType('Inventory');
$Item->setIncomeAccountRef('53');

        if ($resp = $ItemService->add($this->context, $this->realm, $Item))
        {
            return $this->getId($resp);
        }
        else
        {
            print($ItemService->lastError($this->context));
        }
    }

    public function addInvoice($invoiceArray,$itemArray,$customerRef){

        $InvoiceService = new \QuickBooks_IPP_Service_Invoice();

        $Invoice = new \QuickBooks_IPP_Object_Invoice();

        $Invoice = new QuickBooks_IPP_Object_Invoice();

$Invoice->setDocNumber('WEB' . mt_rand(0, 10000));
$Invoice->setTxnDate('2013-10-11');

$Line = new QuickBooks_IPP_Object_Line();
$Line->setDetailType('SalesItemLineDetail');
$Line->setAmount(12.95 * 2);
$Line->setDescription('Test description goes here.');

$SalesItemLineDetail = new QuickBooks_IPP_Object_SalesItemLineDetail();
$SalesItemLineDetail->setItemRef('8');
$SalesItemLineDetail->setUnitPrice(12.95);
$SalesItemLineDetail->setQty(2);

$Line->addSalesItemLineDetail($SalesItemLineDetail);

$Invoice->addLine($Line);

$Invoice->setCustomerRef('67');


        if ($resp = $InvoiceService->add($this->context, $this->realm, $Invoice))
        {
            return $this->getId($resp);
        }
        else
        {
            print($InvoiceService->lastError());
        }
    }

    public function getId($resp){
        $resp = str_replace('{','',$resp);
        $resp = str_replace('}','',$resp);
        $resp = abs($resp);
        return $resp;
    }  

}

Now in app/Http/routes.php, add the following route

Route::get('qbo/oauth','QuickBookController@qboOauth');
Route::get('qbo/success','QuickBookController@qboSuccess');
Route::get('qbo/disconnect','QuickBookController@qboDisconnect');

Now in a page, where you want to show quickbook connect button, add the following code in header section, In mine case, I have added in app.blade.php

<script type="text/javascript" src="https://appcenter.intuit.com/Content/IA/intuit.ipp.anywhere.js"></script>
<script type="text/javascript">
intuit.ipp.anywhere.setup({
menuProxy: '<?php print(env('QBO_MENU_URL')); ?>',
grantUrl: '<?php print(env('QBO_OAUTH_URL')); ?>'
});
</script>

In body of that page include the following line of code
<?php
$qbo_obj = new \App\Http\Controllers\QuickBookController();
$qbo_connect = $qbo_obj->qboConnect();
?>
@if(!$qbo_connect)
<ipp:connectToIntuit></ipp:connectToIntuit>
@else
<a href="{{url('qbo/disconnect')}}" title="">Disconnect</a>
@endif

Make a blade page for success, in resources/views/qbo_success.blade.php, and add the following line of code:

<html>
<head>
    <title>Test</title>
</head>
<body>

<div style="text-align: center; font-family: sans-serif; font-weight: bold;">
    You're connected! Please wait...
</div>

<script type="text/javascript">
    window.opener.location.reload(false);
    window.setTimeout('window.close()', 2000);
</script>

</body>
</html>

I have made 3 function in a above given controller to show how to add item, customer and invoices.

createCustomer - for adding customer to quickbook
addItem - For adding item to quickbook
addInvoice - for adding invoices

Hope it will help you.

Thanks
