Initiating the payment

PayTabs provides you with the backend packages that make the integrating with PayTabs payment gateway very easy by providing ready-made classes that handle the payment process.

This manual is dedicated to walking you through how to initiate the payment/request payload using the configuration options and parameters that have already been clarified in the previous step, "Step 2 - Configure the integration method". Please follow the below steps to initiate a Hosted Payment Page via this package:

First thing, assigning the PayTabs Node.js module paytabs_pt2 to a variable and set the configs as mentioned on the previous step.
```
const PayTabs = require('paytabs_pt2');

PayTabs.setConfig( profileID, serverKey, region);
```

Then, you MUST call the createPaymentPage() function to initiate the payment page along with passing the payment, transaction, cart, URLs, customer, and shipping details to initiate a pre-filled payment page with your provided information.

let paymentMethods = ["all"];

let transactionDetails = [
    transaction.type,
    transaction.class
];

let cartDetails = [
    cart.id,
    cart.currency,
    cart.amount,
    cart.description
];

let customerDetails = [
    customer.name,
    customer.email,
    customer.phone,
    customer.street,
    customer.city,
    customer.state,
    customer.country,
    customer.zip,
    customer.IP
];

let shippingDetails = customer_details; // If both are the same, otherwise set the shipping details.

let response_URLs = [
    url.response,
    url.callback
];

let lang = "ar";

callback = function ($results) {
    console.log($results);
}

let frameMode = true;

PayTabs.createPaymentPage(
    paymentMethods,
    transactionDetails,
    cartDetails,
