## Client ID & Secret  
Once Movement SDK access is enabled, your Developer account is provisioned with a unique **Client ID** and corresponding **Client Secret**.

These two values are required during SDK implementation:

- [Android - Configure Movement SDK](https://docs.foursquare.com/developer/docs/movement-sdk-android-get-started#3-configure-the-movement-sdk)
- [iOS - Configure AppDelegate](https://docs.foursquare.com/developer/docs/movement-sdk-ios-get-started#b-configure-your-appdelegate)

## Bundle IDs & Key Hashes  
In order for the Movement SDK to authenticate with our server, you'll need to add either your **Android Key Hash** or **iOS Bundle ID** to your Foursquare app's configuration.

These two values are required during SDK implementation:

- [Android - Register App Key Hashes](https://docs.foursquare.com/developer/docs/movement-sdk-android-get-started#1-register-your-apps-key-hashes)
- [iOS - Register App Bundle ID](https://docs.foursquare.com/developer/docs/movement-sdk-ios-get-started#1-register-app-bundle-id)
