# Bridge SDK quickstart

> Embed a hosted GBG Go journey in your iOS, Android, or web app. Pick your platform and follow its getting started guide.

The Bridge SDKs embed a hosted GBG Go journey in your app. On iOS and Android, the journey runs in a WebView. On the web, it runs in an iframe on your page.

Each platform has its own getting started guide, which takes you from installing the SDK to a running journey.

## Before you start

Before you follow a guide, make sure you have:

* A published journey. To build one, see the [Platform quickstart](https://docs.go.gbgplc.com/docs/go-v2/get-started/quickstart/quickstartbusiness.md).
* An API client, with its client ID and client secret. See [Manage API clients](https://docs.go.gbgplc.com/docs/go-v2/platform/account-management/manage-api-clients.md).
* A backend that creates the journey URL the app loads.

> [!NOTE]
>
> Your backend creates the journey URL with the [Core SDK](https://docs.go.gbgplc.com/docs/go-v2/get-started/quickstart/quickstart-core-sdk.md), so your client secret never reaches the device. For how to set that up, see the journey URL guide for [iOS](https://docs.go.gbgplc.com/docs/go-v2/developer-integration/sdks/ios/journey-url.md), [Android](https://docs.go.gbgplc.com/docs/go-v2/developer-integration/sdks/android/journey-url.md), or the [web](https://docs.go.gbgplc.com/docs/go-v2/developer-integration/sdks/web/journey-url.md).
