How to set Tax and Shipping fees in Laravel Paypal package - php

Question

Recently i'm working on a laravel project which i choose to use srmklive/laravel-paypal as my paypal payment gateway plugin, but i found that i cannot add Tax and shipping fees, i have read the readme.doc multiple time and also check the paypal documentation, but i still confused on how to add the tax and shipping fees.
Did any one know how to add these data when setExpresssCheckout?
here is my code:
$provider = new ExpressCheckout;
$provider = PayPal::setProvider('express_checkout');
$itemsArr = $data = [];
// add items
foreach ($order->orderProduct as $order_product) {
array_push($itemsArr, [
'name' => $order_product->product->name,
'price' => $order_product->price,
'qty' => $order_product->quantity
]);
}
// add shipping fees
array_push($itemsArr, [
'name' => "Shipping Method : ".$order->shipping_method,
'price' => $order->shipping_fees,
'qty' => 1
]);
$data["items"] = $itemsArr;
$data['invoice_id'] = 1;
$data['invoice_description'] = "Order #1 Invoice";
$data['return_url'] = url('/payment/success');
$data['cancel_url'] = url('/cart');
$total = 0;
foreach($data['items'] as $item) {
$total += $item['price']*$item['qty'];
}
$data['total'] = $total;
$options = [
'BRANDNAME' => 'Ulife',
'LOGOIMG' => asset("images\ulifelanding.png"),
'CHANNELTYPE' => 'Merchant'
];
$response = $provider->setCurrency('MYR')->addOptions($options)->setExpressCheckout($data);
Ps: i also asked on the github, but still confused.

Answer 1

I don't know who still needs an answer for this question, but I share ("srmklive/paypal": "~1.0").
go to ExpressCheckout.php and go to setExpressCheckout add this :
'PAYMENTREQUEST_0_AMT' => $data['total']+$data['tax'],
'PAYMENTREQUEST_0_TAXAMT' => $data['tax'],
and you checkoutData put now:
'tax'=>xx
call your provider with addOptions:
example:
$options = [
'BRANDNAME' => 'MyBrand',
'LOGOIMG' => 'https://example.com/mylogo.png',
'CHANNELTYPE' => 'Merchant',
];
$provider->addOptions($options)->setExpressCheckout($checkoutData)
