자체 계정 시스템을 계속 사용하는 동안 사용자를 게임에 원활하게 로그인합니다. Play 게임즈 서비스 리콜 API를 사용하면 게임 내 계정을 Google Play 게임즈 서비스 계정과 연결할 수 있습니다. 그런 다음 사용자가 여러 기기에서 게임을 플레이하거나 (또는 게임을 재설치한 후 동일한 기기에서 게임을 플레이) 연결된 게임 내 계정을 쿼리하고 로그인 흐름을 간소화할 수 있습니다.
Android Recall API와 통합한 경우 이러한 Recall API가 익숙할 것입니다. Play 게임즈 서비스 리콜과의 모든 서버 측 통합은 Android와 PC에서 동일하므로 PC 타이틀에서 재사용할 수 있습니다.
Play Console에서 Play 게임즈 서비스 설정을 완료하면 게임에 연결된 Play 게임즈 서비스 프로젝트 ID가 생성됩니다. Play Console의 Play 게임즈 서비스 구성 페이지에서 찾을 수 있는 이 프로젝트 ID를 사용하여 게임의 manifest.xml를 업데이트합니다.
이 호출은 백엔드에서 Play 게임즈 서비스 사용자와 게임 내 계정을 연결 및 연결 해제하기 위해 Google에 서버 측 호출을 실행하는 데 사용하는 세션 ID를 반환합니다.

With Play Games Services Recall APIs you can link in-game accounts with\na Google Play Games Services account, then when a user plays your game across\ndifferent devices (or the same device after re-installing your game) you query\nthe linked in-game account and streamline the sign-in flow.\n\nIf you have integrated with the [Android Recall APIs](/games/pgs/recall/recall-setup), these\nRecall APIs should look familiar. Any server-side integrations with Play Games\nServices Recall can be reused by PC titles as they are the same across both\nAndroid \\& PC.\n\nPrerequisites\n-------------\n\n- Complete the [SDK setup](/games/playgames/native-pc/setup).\n\n- Read the overview of [Play Games Services Recall API](/games/pgs/recall).\n\n- Complete [Google Play Games Services setup](/games/pgs/console/setup) in the Play Console.\n\n**Step 1**: Add your Play Games Services project ID in the manifest\n-------------------------------------------------------------------\n\nAfter completing the Play Games Services setup in the Play Console, your game\nnow has an associated Play Games Services' project ID. Using this project ID,\nwhich can be found inside Play Games Service's\n[Configuration page](https://play.google.com/console/u/0/developers/app/games/configuration-summary) in the Play Console, update\nyour game's `manifest.xml`.\n\nExample `manifest.xml` contents: \n\n \u003c?xml version=\"1.0\" encoding=\"utf-8\"?\u003e\n \u003cManifest version=\"1\"\u003e\n \u003cApplication\u003e\n \u003cPackageName\u003e\u003cvar translate=\"no\"\u003ecom.example.package\u003c/var\u003e\u003c/PackageName\u003e\n \\\u003cPlayGamesServices\\\u003e\n \\\u003cProjectId\\\u003e\u003cvar translate=\"no\"\u003e123456789\u003c/var\u003e\\\u003c/ProjectId\\\u003e\n \\\u003c/PlayGamesServices\\\u003e\n \u003c/Application\u003e\n \u003c/Manifest\u003e\n\n**Step 2**: Request Recall access when signing-in\n-------------------------------------------------\n\n| **Tip:** We recommend using the Recall API to query for linked in-game accounts each time your game is launched. For new installs a linked in-game account can be used to seamlessly sign-in a user and restore their progress. For existing installs, when the linked in-game account changes it signals that the user switched accounts on a different device and you can save them time by switching to that account.\n\nWhen your game is handling a sign-in flow, for example adding an in-game\naccount, request Recall access using\n[`GamesRecallClient::RequestRecallAccess()`](/games/playgames/native-pc/reference/class/google/play/games/recall/games-recall-client#requestrecallaccess).\n\nThis call returns a session ID which is used by your backend to make server-side\ncalls to Google for linking \\& unlinking your in-game accounts with a Play Games\nServices user. \n\n auto promise = std::make_shared\u003cstd::promise\u003cRecallAccessResult\u003e\u003e();\n games_recall_client.RequestRecallAccess(params, [promise](RecallAccessResult result) {\n promise-\u003eset_value(std::move(result));\n });\n\n auto recall_access_result = promise-\u003eget_future().get();\n if (recall_access_result.ok()) {\n auto recall_session_id = recall_access_result.value().recall_session_id;\n // Pass the recall session ID to your backend game server so it can query\n // for an existing linked in-game account.\n // - If you discover an existing linked in-game account, continue to sign-in\n // the in-game account. This provides a seamless cross-device sign-in\n // experience.\n // - If there is not an existing linked in-game account, when the user\n // completes the sign-in using your in-game account system record the\n // account linking with Play Games Services Recall. This helps to provide\n // a seamless cross-device sign-in experience when the user returns on a\n // different device or after re-installing your game on the same device.\n } else {\n // Handle the error\n }\n\n**Step 3**: Process the Recall session ID\n-----------------------------------------\n\nOnce your game has the Recall session ID and has passed it to you backend game\nserver, use the [Play Games server-side REST APIs](/games/services/web/api/rest/v1/recall) to:\n\n- Querying for existing linked in-game accounts using [`recall.retrieveTokens`](/games/services/web/api/rest/v1/recall/retrieveTokens)\n- Add or update linked in-game accounts using [`recall.linkPersona`](/games/services/web/api/rest/v1/recall/linkPersona)\n- Delete linked in-game accounts using [`recall.unlinkPersona`](/games/services/web/api/rest/v1/recall/unlinkPersona)\n\nFor a more detailed guide covering the server-side integration see the\ndocumentation covering how to\n[use the Recall API within your game server](/games/pgs/recall/recall-setup#using-recall)."]]
