# Types of Integration

PayKun Checkout offers three different types of Integrations:

1. Web-Hosted Checkout
2. JS Checkout
3. Seamless Checkout (PCI required)

### **1.Web-Hosted Checkout**

It is the simplest and easiest way of checkout. When a customer clicks on the “Pay Now” button on the merchant’s website, they will be redirected to the PayKun Payment Gateway Checkout page. Here, customers would choose online payment modes and fill up other payment details to make the payment.

### [**2.JS Checkout**](/technical-guide/web-integration/js-checkout.md)

In this type of payment mode, clicking on “Pay Now” will display a Pop Up, where the customer needs to fill up all the personal and necessary information and it will be sent to payment gateway server.

### **3.Seamless Checkout (PCI required)**

Seamless Checkout offers true branding, where merchants can create and customize their own Checkout pages and all payment details will be sent to their servers. Hence customer will be able to complete payment without leaving merchant website. (Customer may be redirected to banks authorization page)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.paykun.com/technical-guide/untitled/types-of-integration.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
