# Introduction

With the client configuration parameters, you can customize the appearance and behavior of IVION. You can use these parameters in multiple ways:

- Using the *configs* resource, exposed as `api/configs` on the REST interface, editable via the configuration panel
- By passing parameters to the `getAPI() `method when embedding with the IVION Frontend API as specified in [ConfigurationInterface.](https://ivion-api.docs.navvis.com/latest/reference/interfaces/configurationinterface.html)
- By passing parameters in the URL, e.g. `http://hostname/iv/?lang=de`.

URL parameters override constructor parameters, and constructor parameters override those from the server.

See [Client Configuration Parameters](/v1/docs/client-configuration-1) for the full list of configuration parameters.
