# Info.plist Keys

The Mapbox iOS SDK supports custom `Info.plist` keys in your application in order to configure various settings.

## MGLMapboxAccessToken

Set the [Mapbox access token](https://www.mapbox.com/help/define-access-token/) to be used by all instances of `MGLMapView` in the current application.

Mapbox-hosted vector tiles and styles require an API access token, which you can obtain from the [Mapbox account page](https://www.mapbox.com/studio/account/tokens/). Access tokens associate requests to Mapbox’s vector tile and style APIs with your Mapbox account. They also deter other developers from using your styles without your permission.

As an alternative, you can use `+[MGLAccountManager setAccessToken:]` to set a token in code. See [our guide](https://www.mapbox.com/help/ios-private-access-token/) for some tips on keeping access tokens in open source code private.

## MGLMapboxAPIBaseURL

Use this key if you need to customize the API base URL used throughout the SDK. If unset, the default Mapbox API is used.

The default value is `https://api.mapbox.com`.

## MGLMapboxMetricsEnabledSettingShownInApp

If you have implemented custom opt-out of Mapbox Telemetry within the user interface of your app, use this key to disable the built-in check for opt-out support. See [this guide](https://www.mapbox.com/ios-sdk/#telemetry_opt_out) for more details.
