@Alex Thanks for your help, it's helped me lot. I have tried same in my service but it showing below error,
<br /> <b>Fatal error</b>: Uncaught PrestaShopException: Fatal error in /home/asdarmavanima/public_html/classes/Tools.php: 1109 Stack trace: #0 /home/asdarmavanima/public_html/classes/Product.php(3208): ToolsCore: :displayError() #1 /home/asdarmavanima/public_html/classes/Product.php(4804): ProductCore: :getPriceStatic(1154, false, 0, 6, NULL, false, true, 1) #2 /home/asdarmavanima/public_html/classes/Cart.php(811): ProductCore: :getProductProperties(1, Array) #3 /home/asdarmavanima/public_html/classes/Cart.php(1916): CartCore->getProducts() #4 /home/asdarmavanima/public_html/classes/Carrier.php(738): CartCore->getOrderTotal(true, 4) #5 /home/asdarmavanima/public_html/mobapi/shippingcharge.php(18): CarrierCore: :getCarriersForOrder(3, '3', Object(Cart)) #6 {main } thrown in <b>/home/asdarmavanima/public_html/classes/Tools.php</b> on line <b>1109</b><br />
When I check this line by line it's getting issue on the line on Carrier.php class. !Carrier::checkDeliveryPriceByPrice($row['id_carrier'], $cart->getOrderTotal(true, Cart::BOTH_WITHOUT_SHIPPING), $id_zone, $id_currency)
$cart->getOrderTotal(true, Cart::BOTH_WITHOUT_SHIPPING) this method call getting issue.
