To do so, you'll need to do both of\nthe following:\n\n- Modify your app client to send an App Check token along with each request to your backend, as described on this page.\n- Modify your backend to require a valid App Check token with every request, as described in [Verify App Check tokens from a custom backend](/docs/app-check/custom-resource-backend).\n\nBefore you begin\n\nAdd App Check to your app, using the [default providers](/docs/app-check/cpp/default-providers).\n\nSend App Check tokens with backend requests\n\nTo ensure your backend requests include a valid, unexpired, App Check token,\nprecede each request with a call to `AppCheck::GetAppCheckToken()`. The App\nCheck library will refresh the token if necessary.\n\nOnce you have a valid token, send it along with the request to your backend. The\nspecifics of how you accomplish this are up to you, but *don't send\nApp Check tokens as part of URLs*, including in query parameters, as this\nmakes them vulnerable to accidental leakage and interception. The recommended\napproach is to send the token in a custom HTTP header.\n\nFor example: \n\n void CallApiExample() {\n firebase_app_check::AppCheck* app_check = firebase::app_check::AppCheck::GetInstance();\n Future\u003cstd::string\u003e app_check_future = app_check-\u003eGetAppCheckToken(false);\n app_check_future.OnCompletion([&](const Future\u003cstd::string\u003e& future_token) {\n if (future_token.result()) {\n // Got a valid App Check token. Include it in your own http calls.\n }\n }\n }"]]
