# Interface: IAuWidgetAjaxConfig

Provides properties that are used to send requests to the server and receive responses.

You can use these properties in **params** of the [AuWidgetAjax](../classes/auwidgetajax.md) class.

The following example illustrates how you can populate a gallery with images obtained through an HTTP request.
```
{
  "widgets": [
   {
     "name": "gallery-images",
     "type": "ajax",
     "params": {
       "lock": "gallery",
       "url": "https://example.com/api/images?subfolder=cats",
       "method": "GET",
       "responseType": "json"
     }
   }
 ]
}
```
