# Overlay Embed
The Overlay embed implementation allows you to embed the Paychant widget into your app or website. This method of integration opens the Paychant widget as a pop-up overlay on your app or website when the Javascript SDK is loaded. No new tab, this experience enables users to remain on your app or website.
**Using the Paychant Javascript SDK**
The method for this implementation is by placing the Paychant SDK right into your HTML files using a script tag, and the SDK will load via a CDN. Below is how to do the integration.
```html
Paychant
```
By clicking the button, the Paychant widget is going to pop up.
The available configuration parameters that can be passed to Paychant, can be found [here](/integrations/parameters.md).
