# URL Configuration Parameters

URL parameters are used to configure Pannellum. If an `equirectangular` image
is being used without some of Pannellum's more advanced features, Pannellum can
be configured with just URL parameters; else, a JSON configuration file needs
to be used with the `config`.


## `config`

Specifies the URL of a JSON configuration file.


## Other parameters

A subset of the JSON configuration file options can be used as URL parameters.
These include `panorama`, `config`, `author`, `title`, `hfov`, `minHfov`, `maxHfov`,
`pitch`, `minPitch`, `maxPitch`, `yaw`, `minYaw`, `maxYaw`,
`haov`, `vaov`, `vOffset`, `autoLoad`, `autoRotate`, `firstScene`,
`ignoreGPanoXMP`, `preview`, `fallback`, `compass`, `showFullscreenCtrl`,
`showZoomCtrl`, `keyboardZoom`, `mouseZoom`, `doubleClickZoom`,
`disableKeyboardCtrl`, `draggable`, `showControls`, and `dragConfirm`.
