Additionally, if you use Google sign-in as an authentication provider, an underlying OAuth 2.0 client ID is created for each app in your project. There's a limit of around 30 client IDs that can be created within a single project.</p> <p>You should ensure that all Firebase Apps within a single Firebase project are platform variants of the same application from an end-user perspective. For example, if you develop a white label application, each independently labeled app should have its own Firebase project, but the Apple and Android versions of that label can be in the same project.

The ratio of verified/sent is your success rate. Healthy success rates are commonly in the 70-85% range since SMS is not a guaranteed delivery protocol, and some regions may experience abuse.

The <code translate="no" dir="ltr">localhost</code> domain is added by default to the approved authentication domains to simplify development.

Client apps need to add message handling logic to handle notification messages when the app is in the foreground on the device.

If your organization has a firewall that restricts the traffic to or from the Internet, you need to configure it to allow connectivity with <span class="notranslate">FCM</span> in order for your <span class="notranslate">Firebase Cloud Messaging</span> client apps to receive messages.

For small writes, this limit is approximately 1000 write operations per second. If you are approaching this limit, <a href="https://firebase-google-com.translate.goog/docs/database/admin/save-data?_x_tr_sl=pl&_x_tr_tl=ar&_x_tr_hl=en-GB#section-update"> batching operations using multi-path updates</a> can help you achieve higher throughput.</p> <p>In addition, each database instance has <a href="https://firebase-google-com.translate.goog/support/faq/?_x_tr_sl=pl&_x_tr_tl=ar&_x_tr_hl=en-GB#pricing-simultaneous">a cap on the number of simultaneous database connections</a>. Our default limits are large enough for most applications.

To decrease your downloads, try the following steps:</p> <ul> <li>Add queries to limit the data that your listen operations return.</li> <li>Check for unindexed queries.</li> <li>Use listeners that only download updates to data — for example, <code translate="no" dir="ltr">on()</code> instead of <code translate="no" dir="ltr">once()</code>.</li> <li>Use security rules to block unauthorized downloads.</li> </ul> <p><strong>If you're over your storage limit,</strong> upgrade your pricing plan to avoid service disruptions. To reduce the amount of data in your database, try the following steps:</p> <ul> <li>Run periodic cleanup jobs.</li> <li>Reduce any duplicate data in your database.</li> </ul> <p>Note that it may take some time to see any data deletions reflected in your storage allotment.</p> <p><strong>If you're over your simultaneous database connections limit,</strong> upgrade your plan to avoid any service disruptions.

To activate fetched values so that they can take effect, call <code translate="no" dir="ltr">activate</code>. This design lets you control when the behavior and appearance of your app changes, because you can choose when to call <code translate="no" dir="ltr">activate</code>. After you call <code translate="no" dir="ltr">activate</code>, your app source code determines when updated parameter values are used.</p> <p>For example, you could fetch values and then activate them the next time a user starts your app, which removes the need to delay app startup while your app waits for fetched values from the service.

" tabindex="-1"><strong><span class="notranslate">Remote Config</span>:</strong> I am making a lot of fetch requests while developing my app. Why doesn't my app always get the latest values from the service when it sends fetch requests?</h4> <p>During app development, you might want to fetch and activate configs very frequently (many times per hour) to let you rapidly iterate as you develop and test your app. To accommodate rapid iteration on a project with up to 10 developers, you can temporarily set a <code translate="no" dir="ltr">FirebaseRemoteConfigSettings</code> object with a low minimum fetch interval (<code translate="no" dir="ltr">setMinimumFetchIntervalInSeconds</code>) in your app.</p> <p></p> <aside class="caution"> Keep in mind that this setting should be used for development only, not for an app running in production. If you're just testing your app with a small 10-person development team, you are unlikely to hit the hourly service-side quota limits. But if you pushed your app out to thousands of test users with a very low minimum fetch interval, your app would probably hit this quota. </aside> <p></p> </div> <div class="expandable" id="remote-config-timing"> <h4 class="showalways" id="remote-config-timing" data-text=" Remote Config: How quickly does the Remote Config service return fetched values after my app sends a fetch request?
