Dynamic Links を使用すると、ユーザーがリンクを開いたプラットフォームで得られる最高のエクスペリエンスを提供できるようになります。iOS または Android で Dynamic Link を開くと、ネイティブアプリのリンク先のコンテンツに直接移動します。パソコンのブラウザで同様の Dynamic Link を開くと、ウェブサイト上の同じコンテンツに移動します。
さらに、Dynamic Links はアプリのインストールが必要な場面でも利用できます。たとえば、Dynamic Link を開いたユーザーの iOS デバイスまたは Android デバイスにアプリがインストールされていない場合にインストールを促し、インストール完了後にアプリを起動してリンクを開くといったこともできます。
仕組み
Dynamic Link は、Firebase コンソール、REST API、iOS または Android ビルダー API を使用して作成します。または、アプリ固有のドメインに Dynamic Link パラメータを追加して URL を設定することで作成できます。これらのパラメータは、ユーザーのプラットフォームとアプリがインストールされているかどうかに応じて、開くリンクを指定します。
ユーザーが Dynamic Links を開くと、アプリがまだインストールされていない場合は Play ストアや App Store に転送され（そのように指定した場合のみ）、アプリのインストールが完了するとアプリが開きます。その後、アプリに渡されたリンクを取得し、アプリに適した方法でディープリンクを処理できます。

The service will be shutting down soon. Follow the [migration guide](/support/dynamic-links-faq#how_should_i_migrate_from_the_service) and see the [Dynamic Links Deprecation FAQ](/support/dynamic-links-faq) for more information.\n\nWith Dynamic Links, your users get the best available experience for the\nplatform they open your link on. If a user opens a Dynamic Link on iOS or Android,\nthey can be taken directly to the linked content in your native app. If a user\nopens the same Dynamic Link in a desktop browser, they can be taken to the equivalent\ncontent on your website.\n\nIn addition, Dynamic Links work across app installs: if a user opens a Dynamic Link on\niOS or Android and doesn't have your app installed, the user can be prompted to\ninstall it; then, after installation, your app starts and can access the link.\n\nHow does it work?\n\nYou create a Dynamic Link either by using the Firebase console, using a REST\nAPI, iOS or Android Builder API, or by forming a URL by adding Dynamic Link parameters to a domain\nspecific to your app. These parameters specify the links you want to open, depending on the\nuser's platform and whether your app is installed.\n\nWhen a user opens one of your Dynamic Links, if your app isn't yet installed, the\nuser is sent to the Play Store or App Store to install your app (unless you\nspecify otherwise), and your app opens. You can then retrieve the link that\nwas passed to your app and handle the deep link as appropriate for your app.\n\nCustom link domains\n\nYou can [create Dynamic Links using\nyour own domain name](/docs/dynamic-links/custom-domains): \n\n```\nhttps://example.com/summer-sale\nhttps://example.com/links/promos/summer-sale\nhttps://links.example.com/summer-sale\nhttps://ex.amp.le/summer-sale\n```\n\nOr, if you don't have a domain for your app, you can use a no-cost custom\npage.link subdomain: \n\n```\nhttps://example.page.link/summer-sale\n```\n\nCreate your subdomain at no charge in the Firebase console.\n\nAll Dynamic Links features, including analytics, post-install attributions, and\nSDK integrations, work with both custom page.link domains and your own\ndomain.\n\nImplementation path\n\n|---|-----------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| | **Set up Firebase and the Dynamic Links SDK** | Enable Firebase Dynamic Links for your Firebase project in the Firebase console. Then, include the Dynamic Links SDK in your app. |\n| | **Create Dynamic Links** | You can create Dynamic Links programmatically or by using the Firebase console. |\n| | **Handle Dynamic Links in your app** | When your app opens, use the Dynamic Links SDK to check if a Dynamic Link was passed to it.
